Reservoir and pump system

Abstract

A water conservation system includes an air conditioner and a storage tank. The air conditioner has a thermostat, compressor, condenser, expansion valve, evaporator coils, and a condensation line ending in a termination line a distance away from the air conditioner, allowing condensation to exit the air conditioner. The storage tank is located near the termination line in order to capture and hold the condensation being expelled out of the air conditioner through the termination line. The storage tank has an interior void for holding and storing the condensed water. The interior void also houses a submersible pump having a motor, check valve, power supply, float switch, and discharge pipe. Condensation flows from the air conditioner condensation line, out the termination line, and into the storage tank via a selectively closeable funnel. The condensation is then selectively removable from the storage tank by actuating the power supply of the submersible pump.

Description

TECHNICAL FIELD

The present disclosure relates to apparatuses, systems, and methods for a reservoir and pump system. More particularly, the present disclosure relates to a reservoir and pump system for the collection and containment of condensation and other water runoff from an air conditioner.

BACKGROUND

Air conditioners, or AC units remove heat from an enclosed space in order to cool the air while also removing humidity from the space. An air conditioning system may also provide heating and ventilation. The typical AC system involves a vapor-compression refrigeration process that is achieved by using forced circulation and phase change of a refrigerant between gas and liquid to transfer heat. In its most simplest form, the refrigeration cycle includes a condensing coil, an expansion valve, an evaporator coil, and a compressor. AC units draw in heat and moisture from the air to cool the air and reduce humidity. During this process, the humidity is turned into condensation. A pipe and drainage system assists with draining the condensation produced during the AC cycle. Most condensate drain lines utilize gravity to assist in the drainage of the excess condensation; however, pumps may also be included to expedite drainage. However, while there are codes and regulations on where it is permitted to dump condensate, there is a lack of water conservation in this field. For example, a typical condensate drain and disposal system regulation requires that the condensate not discharge into a street, alley, or other areas so as to cause a nuisance. There are even additional requirements for handling condensate overflow. While a single AC unit may produce up to 25 gallons a day, and even more on hotter and more humid days, that water simply goes to waste.

Therefore, improvements are needed for AC system condensation collection that reduces water waste, stores the water for later use, and provides a system for using the stored water.

An reservoir and pump system 100, according to at least one embodiment, is shown in FIGS. 1-7. The reservoir and pump system generally includes an air conditioner (not shown or numbered), or AC unit, a reservoir or storage tank 20, and a submersible pump 50. The AC unit may be any suitable AC unit that may be used to remove heat from an enclosed space and to control humidity. The AC unit generally includes a thermostat, a compressor, condenser coils, an expansion valve, evaporator coils, and a condensation line. In particular embodiments, the condensation line terminates at a termination line at a distance away from the air conditioner.

The AC unit components and functions are comparable to a typical air conditioning system. For example, the AC unit includes a thermostat that senses the temperature of the air in the surrounding area and controls the operation of the air conditioner based on the desired temperature settings. A compressor plays a vital role in the refrigeration cycle. It compresses the low-pressure gas refrigerant, typically in a gaseous state, into a high-pressure gas. Condenser coils receive the high-pressure gas refrigerant from the compressor. In addition, the condenser coils remove heat from the refrigerant, causing it to condense into a high-pressure liquid state. The heat extracted from the refrigerant is usually expelled to the outdoor environment. An expansion valve is responsible for receiving the high-pressure liquid refrigerant from the condenser coils. Its function is to restrict the flow of the liquid refrigerant, which results in a drop in pressure. This pressure drop is necessary for the refrigerant to evaporate and absorb heat in the evaporator coils. Subsequently, the evaporator coils receive the low-pressure refrigerant liquid from the expansion valve. As is typical, the evaporator coils are located inside the indoor unit of the air conditioner and are responsible for absorbing heat from the air in the surrounding area. As the refrigerant absorbs heat, it evaporates into a low-pressure gas. A condensation line then collects the condensed water vapor formed on the evaporator coils as a result of the cooling process, which in turn allow the condensation to exit the air conditioner. A termination line 10 is the endpoint of the condensation line and is located a distance away from the air conditioner. The termination line 10 serves as an outlet for the condensation to be safely disposed of, preventing water damage to the unit and surrounding areas. Overall, the AC unit system follows the basic principles of refrigeration and air conditioning, using the compressor, condenser, expansion valve, and evaporator coils to cool and dehumidify the air in the surrounding area.

As shown in FIGS. 1-5, a reservoir or storage tank 20 is located proximate the termination line 10 of the AC unit. The storage tank 20 is sized and configured to hold and store a volume of liquid received from the air conditioner. In example embodiments, the storage tank 20 is configured to hold a volume of liquid between about five and 25 gallons, more preferably about 10 to 20 gallons, for example, about 12.5 gallons. While shown as generally rectangular in shape, having a top surface 22, a bottom surface (not shown or numbered), and four sidewalls 24, the storage tank 20 may be any suitable shape or size. For example, in alternate embodiments, the storage tank may include a round barrel having a removable or selectively closeable lid.

In particular embodiments, the top surface 22 includes a first aperture 26 for allowing the condensed water from the termination line to enter the interior void 28, as depicted in FIG. 5. The top surface 22 further includes a second aperture 29 for allowing a portion of the submersible pump 58 to extend through the top surface, as discussed further below. Finally, a third aperture 32 in the top surface 22 is configured to allow a portion of the power supply 54 to be accessible from the exterior of the storage tank 20.

In example embodiments, the first aperture 26 is sized and shaped for receiving a funnel 30 in order to capture the most condensation possible from the termination line 10 of the AC unit. In particular embodiments, as shown in FIG. 1, the funnel 30 includes a first, wide mouth opening 30a and a second, narrower opening 30b extending through the storage tank top surface 22. A mesh screen or similar device 34 may be coupled to the first opening 30a to prevent debris and other unwanted particles from entering the storage tank 20. In some embodiments, the funnel 30 may further include a selectively closeable cap or lid 36, as shown in FIG. 3. For example, the selectively closeable device may include a removable cap, a sliding cap, or a pivoting cap or lid. This selectively closeable device is beneficial when the air conditioner needs servicing or cleaning, such as with vinegar, and a user wishes to keep the resulting drainage from entering the storage tank.

In example embodiments, the storage tank 20 is formed from any suitable material (e.g., stainless steel, plastic, polymer, metal, composite material, and/or the like) and made using molding or other conventional techniques and equipment (e.g., extrusion molding, injection molded, blow molded, compression molding, rotational molding, thermoforming, 3D printing, casting, etc.). In example embodiments, the storage tank 20 is constructed of a sturdy, durable material that is able to withstand various types of environmental elements and conditions. In example embodiments, the storage tank 20 may include one or more handles or wheels (not shown) for moving or adjusting the position of the storage tank. For example, where it is desired to use the water collected by the storage tank for gardening, one or more wheels may be used to transport the storage tank from one area of the garden to the next. The one or more handles or wheels may also be helpful where the collected water is intended to be deposited into a larger holding tank, for example, for lawn irrigation. In particularly hot environments, the stored water may be routed to an irrigation system for the home or building's foundation to prevent cracking. The water may also be beneficial for water collection that is later filtered for drinking, bathing, or other potable water needs.

Referring now to FIGS. 5-6, the reservoir and pump system 100 includes a submersible pump 50. While described as a submersible pump, it is understood that this description is not limited to submersible pumps and any suitable water pump may be utilized including, but not limited to, submersible sump pump, pedestal sump pumps, battery back-up sump pumps, sprinkler pumps, pool pumps, or any other suitable water pump.

In example embodiments, the submersible pump 50 includes a motor (housed within the pump), a check valve 52, a power supply 54, a vertical float switch 56, and a discharge pipe 58. The submersible pump 50 may be used to remove the water that has been collected and stored by the storage tank 20. Thus, the water may enter the pump 50 through a suction inlet or similar opening and exit the pump through the discharge pipe 58 when the pump is actuated, or turned on. The pump 50 is equipped with a float switch 56 that activates the pump when the later level reaches a particular height. The water may then be expelled through the discharge pipe.

The check valve or backflow preventer 52 is installed in the discharge pipe 58 of the submersible pump and helps to ensure the efficient and effective operation of the pump. The check valve 52 is designed to allow water to flow in only one direction to prevent backflow of the water back into the storage tank once it has been pumped out. When the pump 50 is actively pumping out the water, the water pushes against the check valve 52, opening it and allowing the water to flow out through the discharge pipe 58. When the pump is in the OFF state, the check valve automatically closes, preventing any water from flowing back into the pump. In particular embodiments, the check valve 52 is formed from any suitable, durable material such as PVC, ABS, or metal.

The submersible pump 50 includes a power supply 54 that may be coupled to a power source 70 for providing electricity to the pump. Any suitable power supply may be used to supply electricity to the pump. In example embodiments, the power supply may be an AC power supply, a DC power supply, or a solar power supply. In some embodiments, the pump 50 may be powered by a direct electrical connection by hardwiring the pump directly to an electrical circuit. In embodiments where the storage tank will need to be transported, the pump 50 may include a power supply having a plug for connecting to an existing electrical outlet. In particular embodiments, the pump 50 may also include a battery backup system in case of power outages. A backup power supply, such as an uninterruptible power supply, can be connected to the pump and may kick in during any power outages. In alternate embodiments, as shown in FIG. 7, the pump 50 may be powered by solar energy through the use of solar panels 60 and a solar power system. In example embodiments utilizing solar power, the system includes one or more solar panels, a charge controller, battery storage, and an inverter.

The float switch 56, while described as a vertical float switch, may be any suitable float switch including a tethered float switch. In example embodiments, the float switch is used to detect the level of liquid or water in the storage tank 20. The float switch 56 includes a buoyant float 62 attached to a switch mechanism 64. As the liquid level rises or falls, the float 62 also moves up or down accordingly. When the water reaches a particular level, the float 62 triggers the switch 64, either by physically moving it or through magnetic or electrical signals. The float switch 56 is useful in controlling the pump system by allowing a user to switch between an ON state and an OFF state. In various embodiments, the switch may be any suitable switch including a toggle switch, rocker switch, pus-button switch, rotary switch, etc.

The discharge pipe 58 has a first end coupled to the pump 50 and a second end that extends through the top surface 22 of the storage tank to the exterior of the storage tank. In particular embodiments, a spigot or valve 66 is coupled to the second end of the discharge pipe 58. The discharge pipe 58 is generally constructed from a rigid material such as PVC, or any other suitable material that can handle the flow of water and resist corrosion. In example embodiments, the pipe 58 is coupled to the second end or discharge end of the discharge pipe and coupled to a spigot 66. In particular embodiments, the spigot 66 may include a Y-shaped splitter having a first arm 66a with a first opening and a second arm 66b having a second opening. When the condensed water is pumped through the discharge pipe 58 to the spigot 66, the condensed water may flow out of at least one of the first opening and the second opening. In particular embodiments, each arm of the Y-shaped splitter includes a valve shut off 68 for diverting the water between either the first arm or the second arm, or entirely preventing the water from exiting the system. Thus, the first and second valve shut offs 68 allow for single or dual flow of the water. In some embodiments, the spigot 66 includes a backflow preventer device. In various embodiments, the spigot may be coupled to a typical garden hose or other accessory for directing or aiming the flow of the water. In some embodiments, the installed pump 50 is capable of running two 25 foot soaker hoses simultaneously.

When the power supply 54 of the pump 50 is activated, the condensed water is pumped from the storage tank 20, though the discharge pipe 58, and out the spigot 66. Thus, the water is selectively removable from the reservoir 20 when the power supply 54 is actuated.

Particular embodiments and features have been described with reference to the drawings. It is to be understood that these descriptions are not limited to any single embodiment or any particular set of features, and that similar embodiments and features may arise or modifications and additions may be made without departing from the scope of these descriptions and the spirit of the appended claims.
