Description

BACKGROUND AND PRIOR ART

[0002] Many problems currently exist for traditional power generation methods and systems. Approximately 95% of the current world's supply of electrical energy is produced from non-renewable sources. Alternative fuels are not practical sources for taking care of all the world's electrical energy needs. For example, solar energy power is too low, not reliable and the equipment is very expensive. Wind energy is inconsistent, not dependable, expensive, and high maintenance. Geothermal energy is only available at specific locations. Hydrogen energy has no existing infrastructure to support distribution and requires a great deal of energy to produce.

[0003] Global energy demand is increasing at approximately 2% per year. The Department of Energy has forecast by year 2020 that United States will need approximately 403 gigawatts (403 billion watts) and the world will need approximately 3,500 gigawatts (3.5 trillion watts of power). Today, there are more than two billion people in the world who do not have access to electricity.

[0004] Demand for electricity is outrunning capacity, and the price mechanism is the essential way to restrain demand and encourage supply. Therefore, the cost of electricity will keep going up.

[0005] Current electric utility companies are limited by production capacity to increase their electricity generation. To increase generation, these companies must build additional plants which require substantial capital investments, political issues of where to locate to the plants, lengthy permit procedures lasting several years, cost overruns, which make the traditional method of building additional plants undesirable.

[0006] Using nuclear power, oil burning plants, and coal burning plants, adds further environmental problems for those seeking to build electricity generating power plants. Thus, building more and more plants is not a practical solution.

[0007] Current energy conversion efficiency of any of these power plants is generally no higher than 30% (thirty percent) efficiency of the electricity produced from the energy source of the fuel (oil, coal, nuclear, natural gas). For example, turbines that generate the electricity from the fuel source at the power plants only generate up to approximately 30% efficiency of the electricity generated from the energy source. Seventy percent (70%) of the available energy is lost as heat.

[0008] Next, the electricity being transmitted loses energy (efficiency) while it is being transmitted. Energy (efficiency) is lost over transmission lines (i.e. wires, substations, transformers) so that by the time the electricity reaches the end user, an additional 28% (twenty eight percent) energy (efficiency) is lost. By the time the electricity reaches an end user such as a home residence, the true energy efficiency is no more than approximately 18% (eighteen percent) from the actual energy source.

[0009] Co-generation heat is the amount of heat that is wasted in the development of the electric power at the plant because heat cannot be transmitted over long distances.

[0010] A co-generation combined system does exist where some of the co-generated heat produced from a gas fired plant is used to produce additional steam which then makes additional electricity in addition to the primary electrical generation system. This combined system can achieve up to approximately 45% (forty five percent) energy conversion efficiency. But there still are transmission losses of some 28% (twenty eight percent) so that by the time electricity reaches the end user only some 22% (twenty two percent) of the actual energy source is available as electrical power.

[0011] The current electricity rate structure for consumers penalizes the consumers who must pay for the fuel being used to generate either 18 percent or 22 percent energy available to the end user. In essence, the consumer is paying for some 500% (five hundred percent) of the actual cost of electricity by inherent transmission losses that result in the current power generation and transmission systems.

[0012] The inventors are aware of several patents used for steam power generation. See for example, U.S. Pat. No. 3,567,952 to Doland; U.S. Pat. No. 3,724,212 to Bell; U.S. Pat. No. 3,830,063 to Morgan; U.S. Pat. No. 3,974,644 to Martz et al.; U.S. Pat. No. 4,031,404 to Martz et al.; U.S. Pat. No. 4,479,354 to Cosby; U.S. Pat. No. 4,920,276 to Tateishi et al.; U.S. Pat. No. 5,497,624 to Amir et al.; U.S. Pat. No. 5,950,418 to Lott et al.; and U.S. Pat. No. 6,422,017 to Basily. However, none of these patents solves all the problems of the wasteful energy conversion methods and systems currently being used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0053] Before explaining the disclosed embodiments of the present invention in detail it is to be understood that the invention is not limited in its application to the details of the particular arrangements shown since the invention is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation.

[0054] FIG. 1 is a flow chart diagram of a preferred embodiment system of the invention. Initially, ambient air comes through an air preheater (1FIG. 1, shown in FIG. 4). The heated air is mixed with natural gas or propane in the airblower/valve assembly 2FIG. 1 (such as but not limited to an AMETEK Variable Speed Power Burner Blower, or EBM, with gas metering devices such as those manufactured by Honeywell and Carl Dungs, and the like.) The airblower/valve assembly 2 supplies the air required for the combustion process from a primary fuel source 22. The forced air blower can be sized based on the application and/or requirements of the heat generator 3FIG. 1. The gas metering portion of the airblower/valve assembly 2 provides the gaseous fuel (natural gas, propane, and the like.) required for the combustion process. This device can regulate the amount of gaseous fuel to provide the optimum stoichiometric air to fuel ratio (e.g. for natural gas, that ratio is approximately 10 to approximately 1). The gaseous fuel enters the forced air stream through the device. Alternative fuels can be used as a back up fuel source 23, if the current fuel supply is disrupted. The device can automatically shift to the back up source 23, such as but not limited to propane tanks, by switching to a different gas/air mixture and other adjustments which can automatically occur.

[0055] The invention can incorporate the latest in modulating blower, valve 2 and burner technology in heat generator (boiler) 3. This allows the proper air/gas mixture at all inputs determined by a feedback signal from the electric load placed on the electric generator 9.

[0056] The proper gas air mixture (approximately 10 air to approximately 1 gas) is injected by blower 2 (a combination air blower fan and gas metering device) into a burner inside the heat generator unit (boiler) 3FIG. 1 (shown in FIGS. 2A and 2B). Heated combusted gases heats the incoming water from the closed loop system (12, 11, 7, 5, 6, 4FIG. 1). Exhausted flue gasses from boiler 3 pass through heat recovery 4FIG. 1 (shown in FIG. 3), after heating incoming air exhausts into the atmosphere.

[0057] Steam generated in boiler (heat generator) 3FIG. 1 (FIG. 2A or 2B) at a temperature of approximately 1000F and approximately 600PSI enters expander drive 8FIG. 1 (FIGS. 5A, 5B and 6). This steam in expander drive 8 causes a shaft 8SH in the expander to turn, the shaft SH is connected to electric generator 9FIG. 1 (FIG. 11). Electric generator 9 can be a commercial off the shelf generator (COTS) such as Light Engineering Inc., Marathon, e-Cycle. A preferred generator 9 can be a 240 Volt three-phase AC power supply, or 120 Volt single-phase AC power supply, and the like.

[0058] Referring to FIG. 1, electricity produced goes through a power conditioning unit 17FIG. 1 such as those commercial off the shelf units that come with the electric generator 9 previously described, for the purpose of putting the electricity generated into the proper phase and frequency for feeding into an electrical power grid 18FIG. 1. Electric power grid 18 can be an existing grid that supplies electrical power to commercial, industrial and residential applications, such as but not limited to FPL (Florida Power and Light) electric power supply grid. Also, electricity generated out of power conditioning unit 17 powers the air conditioner 19FIG. 1 (FIGS. 10A-10B). The power conditioning unit 17, can be an off-the-shelf unit manufactured by Light Engineering Inc. which adjusts parameters such as phase and harmonics coming out of electric generator 9 and such as a standard AC to DC type converter, and the like.

[0059] Electrical generator heat dissipating units 20, 21 can consist of liquid pump and fan 21 and standard heat exchanger (for example, a radiator, tubes with fins, and the like) 20, for generator 9FIG. 1 cooling and keeps generator at a temperature of approximately 130F or less. Pump portion 21 can be a fractional horsepower circulator of an anti-freeze solution, such as those manufactured by TACO, Grundfos, and the like. Fan portion 21 can be a pancake style blower of approximately 50 CFM (cubic feet per minute) operating at approximately 115 volts such as one manufactured by EBM, and the like. A heat sensitive speed controller (thermostat) such as one manufactured by Honeywell, and the like, can be built into the fan portion, to operate the fan.

[0060] Co Generation Loop.

[0061] From Expander drive 8FIG. 1 (FIGS. 5A, 5B and 6), the steam exhausted goes to a steam to water exchanger 10FIG. 11 (FIG. 7) to a pump 14 (Off the shelf water circulator) to a domestic water heater 15, to a hot water air heating coil 16 such as a room/house hot water space heater (a coil passing through a fan) to other loads 13, such as but not limited to a swimming pool, a spa, underground pipes for ice and snow removal, and the like. Next, the same hot water passes back at a reduced temperature of up to approximately 30F, to heat exchanger 10FIG. 1 (FIG. 7). When co generation loop is completely satisfied (i.e. all the hot water is heated up in domestic water heater 15, no more heat is required for heating house 16, pool/spa is at desired temperature) then in order to dissipate any excess heat, it passes from heat exchanger 10 to steam dissipation coil 11FIG. 1 (FIGS. 8A-8B), where condensed water is placed into accumulator 7 (water storage tank) by way of dissipation coil and the pressure balancing vent check valve, which relieves built up vapor. Then, the high pressure condensate return pump 5FIG. 1 (FIG. 9) pumps water to check valve 6 (keeps water from going backward). Pump 5 can run at approximately 600 to approximately 1,000 psi. Water is then passed to heat recovery unit (reclaimer) 4FIG. 1 (FIG. 3). Water can be heated in recovery unit (reclaimer) 4 and is pumped by a high pressure pump 5 into steam generator (boiler) 3 for heating back into steam to complete the cycle of the entire system, where heat generator (boiler) 3 can operate at a temperature of approximately 1,000 F to approximately 1,500 F.

[0062] In the cogeneration loop of FIG. 1, steam exits the expander drive 8 at a temperature at approximately 212F to approximately 230F. This steam passes through the steam to water exchanger 10 (FIG. 7), such as but not limited to a Alfa Laval CB-14 a COTS item to extract the heat of the steam and transfer it to the co generated water to be used for domestic hot water, heating water to be used for domestic hot water 15 for heating water and other water usages 13 such as but not limited to pools, snow melting, and the like. This co generated water is pumped by a COTS circulator pump 14, such as but not limited to a Taco or Grundfos pump, and the like. In a situation where all co generated heat usages are satisfied, the excess heat (steam) continues on to the heat dissipation coil 11, such as one manufactured by Heatcraft or other steam condenser manufacturers.

[0063] The condensed steam is now changed to water, which gave up its latent heat to the co generated water. The closed loop steam, now water, is transferred to the accumulator 7 passing through check valve 6 ready to be returned to the heat generator 3 by the high pressure bellows pump 5 (FIG. 9).

[0064] FIG. 2A is a cross-sectional view of a dual wrap fin coil heat generator (boiler) for the embodiment of FIG. 1, and can be used for compact spaces when space restricts height dimensions of a boiler. Air blower (2FIG. 1) forces an air/gas fuel mixture to enter burner. Gas/fuel meter in blower/meter 2 (FIG. 1) provides the gaseous fuel (natural gas, propane, and the like) from primary fuel source 22 (FIG. 1) required for the combustion process. This device will regulate the amount of gaseous fuel to provide the optimum stoichiometric air to fuel ratio (e.g. for natural gas, that ratio is 10 to 1). The gaseous fuel enters the forced air stream. Alternative fuels from a backup fuel source 23 (FIG. 1) can be used as a back up if the current fuel supply is disrupted. The device can automatically shift to the back up source 23, such as but not limited to propane tanks, by switching to a different gas/air mixture and other adjustments can be made automatically.

[0065] The burner screens 302, 304 located inside the body of the heat generator 3, is where the fuel and air mixture is ignited and burned. The burner 305 consists of two cylindrical (inner and outer) screens 302, 304. The purpose of the dual screens 302, 304 is to prevent flashbacks from the combustion of the fuel and air mixture. The screens 302, 304 can be made of Inconel or other high temperature materials, and the like.

[0066] Referring to FIG. 2A, heat exchanger (double wrapped fin tubes 310) are wrapped around the burner 305 and can be constructed of approximately {fraction (5/8)}″ 321 stainless steel tubing with external outwardly protruding fins 315. The working fluid (water) is pumped through the heat exchanger (by pump 5FIGS. 1, 9 at approximately 600 to approximately 1000 psi), where it is heated from an approximately 150° F. to 250° F. entering temperature to a leaving temperature of approximately 1000 to approximately 1300° F. (nominal, approximately 1500° F. maximum) at approximately 1000 PSI. Once the working fluid is heated it will then go to the expander drive 8(FIGS. 5A, 5B and 6).

[0067] An electrically powered igniter module 320 attached to the heat generator 3 adjacent to air/gas inlet line 301 can provide the necessary energy (spark) to start the combustion process. The insulation 325 within heat generator housing 330 retains the heat that is generated during the combustion of the fuel and air mixture within the heat generator cavity to maximize the heat transfer to the heat exchanger (wrapped tubes 310). The insulation 325 can be composed of aluminum/silica or other high performance insulation, and the like. Exterior outer generator housing 330 can be composed of stainless steel, aluminum, high temperature plastic, and the like, and houses the insulation 325, heat exchanger 310, and burner screens 302, 304.

[0068] A downwardly extending flue 340 exhausts the products of combustion (flue gases). The flue gases, which are very friendly to the environment are primarily carbon dioxide and water vapor with trace amounts (ppm) of CO and very low (less than 10 ppm NOx. A minimal amount of heat (≦approximately 2% of total heat generated) is also lost through the flue. The flue gases can be harmlessly exhausted to the atmosphere.

[0069] Water entering heat generator (boiler) 3FIG. 1, FIG. 2A from heat recovery (reclaimer 4FIG. 1) is pumped to flow through the double wrapped finned coiled heat exchanger tubes 310, and exits the boiler at approximately 1000F to approximately 1500F to pass to the expander drive 8FIGS. 1, 5A, 5B and 6.

[0070] FIG. 2B shows a cross-sectional view of a single wrap fin coil heat exchanger (boiler) 3′ for the embodiment of FIG. 1 that can be used where height restrictions are not a problem. In FIG. 2B, a plug 350 such as a high temperature insulation material previously described is positioned below a burner, and is used for directing the forced air combustion against the exterior fins on the single layer of wrapped fin covered coil tubes 310′. The upper end 355 of the plug 350 can be chamfered/taperered, and can be conical, and the like. Air swirls and turbulates about the fins 315′ which are about the coil tubes 310′ to maximize heat transfer from the burner 305 to the water circulating through the coils 310′. The function of other components in FIG. 2B is similar to those described in reference to FIG. 2A The heat generators 3 and 3′ of FIGS. 2A-2B produce steam to provide motive power to the system expander. FIG. 2A uses a mono-tube 310 wrapped about it itself, and FIG. 2B is a single wrap mono-tube 310′. The mono-tube 310/310′, has a very small fluid capacity (0.64 gallons of distilled water). Any leakage would release the steam without any explosive power and therefore is a safe device even at the operating pressure of approximately 600 to approximately 1000 psi and temperatures of approximately 1000 to approximately 1300F with a maximum of approximately 1500F. The pressure drop would immediately shut off fuel supply and stop the system operation.

[0071] The forced combustion blower and a modulating gas valve 2FIG. 1, are controlled by the ignition module 320 in FIGS. 2A-2B, which delivers a mixture of fuel gas and air to the burners 305 within the heat generator (boiler) 3, 3′ of FIGS. 2A, 2B. The burner 305 can be one manufactured by Burner Systems Inc. or Cleveland Wire Cloth, where the combustion takes place on the burner surface 302, 304 to heat the water to steam in the heat generator tubes 310, 310′.

[0072] The tubes 310, 310′ in the heat generators 3, 3′ of FIGS. 2A-2B can include approximately 0.018, thick 316 stainless steel fin material of approximately 0.125 height and approximately 0.25 height wrapped and brazed around at approximately 14 to approximately 11 fins per inch. An approximate 0.625 ID (internal diameter), tube of 321 stainless steel of approximately 0.083 wall as required to meet the required pressure vessel codes.

[0073] Referring to FIGS. 2A-2B, heat can be absorbed by the helix (helical) coil tubes 310, 310′ from radiation from the burner flame in burner 305 and from convection of the products of combustion of forced combustion burner 305, to produce output steam flow rate of approximately 95 pounds per hour at approximately 600 psi and approximately 1000F.

[0074] Water in the heating coils 310, 310′ can be heated through the saturated steam range into the superheated steam range realm all in one heat generating path as opposed to standard methods using two stage steam systems with a separate super heat section.

[0075] FIG. 3 shows the heat recovery unit (liquid condensate heat exchanger) 4 for the embodiment of FIG. 1. Flue gas from bottom extending flue 340 passes into a chamber having double wrapped mono-tube finned 410 heat exchanger, and maximizes heat efficiency to water passing through the double wrapped tubes 410 within a housing 430 (similar in material to the housing 330 of the heat generator 3. The Liquid Condensate Heat Exchanger (Reclaimer) 4 captures waste heat in the flue 340, which adds to the overall efficiency of the invention. This heat exchanger 4 can be constructed of 321C stainless steel tubing 410 with 316 stainless steel external fins 415.

[0076] The flue heat reclaimer 4 in FIG. 3 captures heat from the flue gas exhaust to raise the temperature of the water from the steam condenser 10FIG. 1 before it is pumped by the high pressure pump 5FIG. 1 into the heat generator 3FIG. 1.

[0077] The flue heat reclaimer built of the same materials as the heat generator 3FIG. 1 and able to withstand the pressure that exists in the heat generator 3: A spiral baffle 450 can be used to distribute the flue heat to all the tubes 410 for proper heat transfer.

[0078] FIG. 4 shows air preheater component 1 for the embodiment of FIG. 1. A combustion air pre-heater increases the efficiency of the combustion burner 205 of FIGS. 2A, 2B by capturing the heat usually wasted in the flue 440, 140. Energy needed to heat the air in combustion is lowered, increasing the efficiency of the overall system. The pre-heater 110 can be made of stainless steel materials for long life. Ambient air can be pulled into an opening 115 in the annular chamber 110 surrounding the flue 440, 140, by a combination fan/blower and gas valve 2FIG. 1 pulling the heated air out of opening 125 to be directed into the heat generator (boiler) 3FIG. 1.

[0079] FIG. 5A is a perspective view of an expander drive 8 for the embodiment of FIG. 1. FIG. 5B is an internal view of the expander drive of FIG. 5A. FIG. 6 is a cross-sectional view of the expander drive of FIG. 5A along arrows 6X.

[0080] The expander drive 8 converts the thermal energy of the working fluid into mechanical (rotational) energy to drive the generator or any other mechanical device.

[0081] FIGS. 5A, 5B and 6 show an expander drive system based Scroll Labs “floating scroll” technology (see U.S. patent Ser. No. 10/342,954 to one of the inventors of the subject invention, which is incorporated by reference) for the subject invention. The scroll device 8, used as compressors, expanders and vacuum pumps, are well known in the art. In traditional scroll device there is a set of scrolls including one fixed scroll and one orbiting scroll making circular translation, orbiting motion, relative to the former to displace fluid. In a floating scroll device there are two sets of scrolls, front and rear scrolls. Each set of scrolls, front or rear, consists of a fixed scroll and an orbiting scroll. Floating scroll technology adopts dual scroll structure. FIG. 5A is a perspective view of the external appearance of a floating scroll expander drive 8. FIG. 5B is an exploded view of the expander drive 8 of FIG. 5A which shows the internal orbiting scroll of floating scroll expander drive.

[0082] Referring to FIG. 6 the working principle of the floating scroll expander drive is explained. Front fixed scroll 601 and rear fixed scroll 604 are engaged with front orbiting scroll 602 and rear orbiting scroll 603, respectively. The front and rear orbiting scrolls of the dual scroll are arranged back to back and orbit together and can make radial movement relative to each other during operation.

[0083] For simplicity, below we will only describe the working principle of the front scrolls. The working principle of the rear scrolls is similar. The steam enters the expander drive 8 from the inlet port 610 at the center of the front fixed scroll. The steam is then injected into the expansion pockets formed between the scrolls and is expanded during the orbiting motion of the scrolls, and finally, discharges through passage 620 and discharge port 621 at the peripheral portion of the front fixed scroll. There are three substantially similar and uniformly distributed crankshafts (only one 630 is shown). The crankshafts serve three functions: driving, anti-rotation and axial compliance. The one or more crankshafts convert the orbiting motion of the orbiting scroll in to rotation and then drive a generator to produce electricity. The three crankshafts work together to prevent the orbiting scroll from rotation. The crankshafts also allow the orbiting scroll to move axially, (axial compliance), to maintain the radial seal between the tips and bases of the scroll.

[0084] Referring to FIG. 6, the front and rear orbiting scrolls 602 and 603 have front end plate 631 and 632, respectively. There is a plenum chamber 633 formed between the two end plates. Sealing element 634 seals off plenum chamber 633 from surrounding low-pressure area. The plenum chamber 633 is connected to a selected position of expansion pocket formed between the fixed and orbiting scrolls through a passage 635. The forces of the steam acting on the area in the plenum chamber 633 slightly exceed the total axial forces acting on the opposite surface of the front orbiting scroll 602 by the expanding steam. The net axial forces will urge the front orbiting scrolls towards the front fixed scrolls to achieve very light contact between the tips and bases of the mating scrolls 601 and 602. This axial compliant mechanism enables a good radial sealing between expansion pockets and makes the wear between the orbiting and fixed scrolls negligible and self-compensating.

[0085] In the floating scroll, a crankshaft synchronizer 636 is used to keep the orientation of three crankshafts being synchronized. Therefore the orbiting scroll is able to move in the radial direction and keep the flank to flank contact of the spiral walls of the mating scrolls. This is called radial compliance, which enables good tangential seal between expansion pockets formed between the mating scrolls.

[0086] The axial and radial compliant mechanisms enable the orbiting scrolls to be dynamically balanced, yet lightly contacting mating fixed scroll to achieve good and lasting seal for high efficiency and durability. We called it floating scroll technology.

[0087] FIG. 7 shows the steam to water exchanger (Co Generation Steam condenser) 10 for the embodiment of FIG. 1. The invention uses a plate fin exchanger to extract heat from the exhaust of the expander to heat water for co generation usages of domestic hot water, hot water space heating and other incidental usages. The exchanger 10 can be small in size, but able to extract all of the co generated hot water that is available, and can be one manufactured by Alfa Laval, such as model # TK 205411G01. The exchanger 10 allows for fluid flow on one side from expander drive 8 coming in at approximately 212° F. to approximately 230° F. at approximately 2 to 60 psi and going out another end to heat dissipation coil 11 and eventually to return to heat generator (boiler) 3 The other side of the heat exchanger 10 has an opposite flow path with fluid flowing in from co-generation loop 13 (from other loads) and out other end to co-generation recirculation pump 14 at a temperature of approximately 140F.

The steam dissipation coil provides a method of dissipating excess heat and condensing the steam from the expander drive 8 when all co generated heat has been satisfied. This allows the invention system to continue operating and providing electricity to the power grid 18 on a 24 hours-a-day, seven days-a-week basis. The condensate coil 11 can be manufactured by Heatcraft or other fin and tube manufacturers, and is used for the closed loop system, and can be made of stainless steel tubes with aluminum fins.

This can be an off-the-shelf fan device of 115 volt, {fraction (1/6)} horsepower, 1725 RPM with a 16-inch propeller fan putting out 1600 CFM at maximum condition. Air flows from the fan 11F through the coils 11C that are about the flow path lines inside the coil assembly 11.

[0090] FIG. 9 shows the configuration of the condensate return pump (high pressure return pump) 5 for the embodiment of FIG. 1. Low pressure fluid coming from accumulator (water tank) 7FIG. 1 passes into the metal bellow assembly by line 510. The adjustable eccentric drive expands and compresses the metal bellows 520 along double arrow E, producing a high pressure output supply of liquid which passes to check valve 6 out line 530 back to reclaimer 4 and then to heat generator (boiler) 3FIG. 1A fractional electric horsepower motor, M, 560 can be used to rotate an adjustable eccentric wheel drive 550 in the direction of arrow R which can be used to expand and compress the metal bellows pump 520 by a piston type connector 540.

[0091] This high pressure, low volume pump 5 can provide approximately 600 plus PSI condensate water back into the high pressure boiler supply 3. Bellows pump 5 allows for boiler input conditions greater than or equal to approximately 600 PSI, greater than or equal to approximately 200 F, and a mass flow of 95 pounds per hour.

The A/C module unit 19 can consist of variable speed compressor 710, condenser coil 720, refrigerant pump 730, expansion valve 740, evaporator coil 750, variable fan (blower) 760, and variable speed fan (blower) 780. This unit 19 is a straight A/C unit, not a heat pump, as the heat required by the home will be taken from the cogeneration loop of the invention in FIG. 1.

[0094] The air conditioner unit/system 19 can be a high efficiency (approximately 20 SEER) rated to operate on the lowest amount of fuel source needed. The compressor can either be a straight electrically-driven compressor or mechanically driven from the expander drive 8, and can include:

[0095] 1. Refrigerant tubes 790 in the condenser and evaporator can have rifled interior surfaces with added tube turbulators (see 790X).

[0096] 2. Both condenser and evaporator can have variable fan controls to match the loads required by the usage.

[0097] 3. The compressor can be an advanced scroll that can be modulated according to usage needs.

[0098] 4. A liquid refrigerant pump and matched expansion valve can be used for greater system efficiency.

[0099] 5. A quiet and energy-efficient condenser and evaporator fan blades can be used. This can be an off-the-shelf item such as one manufactured by Jet Fan using the Coanda effect.

[0100] 6. A complete model line of approximately 2½ to approximately 5 tons can be available in single and three phase electric input.

[0101] The A/C module can have the highest SEER (Seasonal Energy Efficiency Ratio) rating and lowest cost and will be more reliable than any high-efficiency A/C units in the market today. The operation of the A/C unit and system 19 will now be described in reference to FIG. 10A.

[0102] Starting at heat absorbed from the interior environment by the evaporator coil 750. Air from the interior of a space can be blown over the rifled tube evaporator coil 750 by the variable speed blower (fan) 760. The refrigerant in absorbing heat has been changed to gas. This low pressure gas continues to the air conditioning variable speed compressor 710. A suction accumulator (not shown) can be added to prevent liquid from entering the compressor 710. The compressor 710 intakes the low pressure heated gas to a high pressure heated gas adding the heat of compression. This heated refrigerant gas enters the novel rifled tube (detail 790X shown in FIG. 10B), which causes a turbulated effect inside tube 790 where ambient air (outside air) induced by the quiet blade fan of blower 780 cools the gas into a liquid. This liquid, under pressure from the compressor 710 is further increased in pressure by a liquid refrigerant pump 730 to increase efficiency. This liquid then enters a thermal expansion valve 740, where it is expanded through an orifice into evaporator 750 removing heat from the interior environment of the space being cooled by A/C unit and system 19 to complete the cycle.

[0103] FIG. 11 shows a wiring diagram for various components for FIG. 1. Referring to FIGS. 1 and 11, the heat rejection fans used in the steam dissipation coil assembly 11 can be controlled by a modulating speed motor blower assembly controlled from a heat level feedback from the steam dissipation coil in the dissipation coil assembly 11.

This module also controls the gas ignition device, either a hot surface igniter or spark igniter of 115 volts. Through an internal or external relay it controls the modulating combustion blower and modulating gas valve. It also controls the high-pressure condensate pump and the electric generator cooling circulating pump. This pump modulates according to a temperature signal of the circulating fluid. On separate 115 volt circuits, heat signal modulating fans control the co generation pump, the heat dissipation coil blower fan and the space heating fan in the air conditioning unit evaporator cabinet. The air conditioning unit 119 has its own modulation circuit as described in the air conditioning description previously described.
