Description
TECHNICAL FIELD

The present disclosure relates to systems and equipment for setting up portable gas generators for whole house use.


BACKGROUND

Many places around the world have homes or other small buildings that use air conditioning units which sit outside the walls of the home or building. Such units generally use substantial power to run them. The air conditioning units typically have powerful compressors that are required to be turned on and off by a controller in an attempt to maintain the home at a relatively constant or desired temperature. When these compressors kick on, they typically draw large transient currents from the electrical power source.


Because places that often use air conditioning units also may be susceptible to power outages due to windstorms and the like or power outages due to other reasons, many home owners prefer to have some kind of backup gas, propane, or natural gas generator so that they may continue to run their air conditioning units even during a power outage. If the generator is large enough, the current draw required by the air conditioning unit may not be an issue, however these generators are typically very large and expensive. Many consumers prefer to buy less expensive generators with much lower power capacity and therefore, large current draws may cause these generators to fail because they can't generate enough transient power even if they can accommodate the power of the air conditioner in steady state.

The foregoing summary is illustrative only and is not intended to be in any way limiting. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features will become apparent by reference to the drawings and the following detailed description.





BRIEF DESCRIPTION OF THE DRAWINGS

Illustrative embodiments are illustrated in referenced figures of the drawings. It is intended that the embodiments and figures disclosed herein are to be considered illustrative rather than restrictive.



FIG. 1 is a schematic system diagram of an illustrative embodiment.



FIG. 2 is a flow diagram depicting a method in accordance with an illustrative embodiment.





DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.


Referring now to FIG. 1, a backup whole house generator system 100 is depicted. Backup whole house generator system 100 may include a gas generator 110 having a gas supply 115. Gas supply 115 may be any one of a gasoline supply, a propane supply, or a natural gas supply. Gas Generator 110 may be configured to use any of the particular fuel provided by gas supply 115. In some embodiments gas generator 110 may be a dual-fuel portable gas generator, a gasoline portable generator, a propane portable generator or a natural gas generator. Gas generator 110 has its AC electrical output plugged into a receptacle 120 which may be any form of conventional NEMA plug receptacles or any other type of receptacle or hard-wired connection. Receptacle 120 may be coupled to an interlock switch 130. Interlock switch 130 is used to switch entirely from the standard electrical grid service or other electrical service to gas generator 110 or vice versa. Interlock switch 130 is coupled to a standard electrical panel containing fuses or circuit breakers for household circuits. One electrical circuit of note is a circuit supporting a central air conditioning unit 150. Central air conditioning units of this type require power typically 3000-5000 W (Watts). Portable gas generators such as gas generator 110 generally range in power outputs from 1000 W to 12000 W where the higher the power output is generally related to a higher price. Typically, a whole household can be substantially run, with some limitations using a 7500 W portable gas generator. Typically, when the compressor of central air conditioning unit 150 turns on there are high transient currents drawn by the air conditioning unit on the order of 9000 W to as much as 30000 W depending on the construction and size of the air conditioning unit. Because of this high-power draw due to high transient current demand, if the interlock switch 130 is switched to the gas generator 110, when the air conditioning unit 150 turns on, the transient current draw may go out of the gas generator's power range due to increased transient current draw.


It is not desirable from a cost perspective to purchase a gas generator with a higher power output only to accommodate this high transient current draw. Thus, this system incorporates a current reducer 160 which is designed to reduce the current draw by air conditioning unit 150 generally, but also is able to reduce the transient current draw by air conditioning unit 150. This unique system combines the use of a current reducer 160 to enable the use of lower power and less expensive portable gas generators to power an entire home including the use of the central air conditioning unit 150 which would otherwise not be possible. This unique combination of hardware enables an unexpected and advantageous system to be set up that was not before possible. This unique combination of hardware brings lower priced and simpler whole house backup generator systems to homeowners that was never before possible unless they were to completely turn off their central air conditioning systems.


In some embodiments of system 100, a carbon monoxide (CO) or carbon dioxide (CO2) sensor may be incorporated as part of the system to provide some security to the homeowner that while running the gas generator 110, fumes from the exhaust are not entering the home at a dangerous level of concentration. Such a CO or CO2 monitor may provide any of a variety of alarms including audible, visible, notifications to smartphones or other information displays, or to automatic shut off devices.


Referring now to FIG. 2, a process 200 for setting up a whole house backup generator system using a portable generator is depicted. After purchasing the whole house backup generator system, an installer may provide a gas-powered electrical generator such as described above (Process 210). The installer then couples a cable from the gas generator output to a receptacle (process 220). The installer electrician further installs an interlock switch coupled to the main of the primary electrical panel. (Process 230). If not already installed, an installer couples the air conditioning unit to the electrical panel (Process 240). Whether the air conditioning unit was previously installed or not, a current reducing mechanism is installed in air conditioning unit that is electrically coupled to the electrical panel (Process 250). Current reducing mechanism, such as current reducer 160 may be any type of applicable current reducing mechanism that still allows for the operation of air conditioning unit 150 but decreases the transient power draw to a level below the peak running power of the gas generator 110. In some embodiments the current reducer 160 may be but is not limited to a “5-2-1 Compressor Saver” from CPS Products, Inc. of Hialeah, FL. Many other current reducers or current limiters are available on the market from other manufacturers which may be equally well suited for the system. It has not been contemplated to combine lower wattage portable gas generators with central air conditioning units so that portable gas generators can be used to provide whole house backup power. In one instance the installation of a 5-2-1 Compressor Saver may be combined with the installation of a portable gas generator having a running power of 7500 W. Without the advantageous use of the current reducer, using a gas generator running at 7500 W would never be suitable to run a whole house power including the use of central air conditioning. In some embodiments, the air conditioning unit may be substituted with a heat pump which may provide both heating and cooling to the house.


In some instances, one or more components may be referred to herein as “configured to,” “configured by,” “configurable to,” “operable/operative to,” “adapted/adaptable,” “able to,” “conformable/conformed to,” etc. Those skilled in the art will recognize that such terms (e.g. “configured to”) generally encompass active-state components and/or inactive-state components and/or standby-state components, unless context requires otherwise.


While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to claims containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that typically a disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms unless context dictates otherwise. For example, the phrase “A or B” will be typically understood to include the possibilities of “A” or “B” or “A and B.”


With respect to the appended claims, those skilled in the art will appreciate that recited operations therein may generally be performed in any order. Also, although various operational flows are presented in a sequence(s), it should be understood that the various operations may be performed in other orders than those which are illustrated or may be performed concurrently. Examples of such alternate orderings may include overlapping, interleaved, interrupted, reordered, incremental, preparatory, supplemental, simultaneous, reverse, or other variant orderings, unless context dictates otherwise. Furthermore, terms like “responsive to,” “related to,” or other past-tense adjectives are generally not intended to exclude such variants, unless context dictates otherwise.


While the disclosed subject matter has been described in terms of illustrative embodiments, it will be understood by those skilled in the art that various modifications can be made thereto without departing from the scope of the claimed subject matter as set forth in the claims.
