A compressor is to be used in an air conditioner. The air conditioner includes the compressor, an evaporator, and a container. The evaporator generates condensed water during operation. The container receives the condensed water generated by the evaporator. The compressor includes a main body and a textile member that is capable of transferring moisture and is quick drying. The main body is to be disposed in the container. The textile member covers at least a part of the main body, and is to be used for absorbing the condensed water.

A cooling system for a photovoltaic panel including micro flat heat pipes (HP) integrated with thermoelectric generators (TEG) and a cooled water reservoir for cooling the working fluid in heat pipes. The cooled water in the reservoir is pumped from the condensate pan of an air conditioner. Experimental results show that cooling system reduced the average temperature of the panel by as much as 19 C. or 25%. Further, the output power of the photovoltaic panel increased by 44% when the photovoltaic panel was used in a very hot climate (30-40 C.). An additional two watts of power was generated by the TEGs.

An air conditioning system includes a condenser configured to condense gaseous refrigerant into liquid refrigerant. A sub-cooling conduit may be fluidically coupled to the condenser and configured to receive and sub-cool the liquid refrigerant. A base pan may collect condensate formed from ambient moisture. A condenser fan may blow air in a flow direction toward the condenser. The condenser fan may be positioned relative to the base pan to cause the condenser fan to direct a volume of condensate from the base pan onto the sub-cooling conduit. A method of sub-cooling refrigerant for air conditioning may include condensing refrigerant, and collecting condensate formed from ambient moisture in a base pan. The method may further include directing a volume of condensate from the base pan onto a sub-cooling conduit fluidically coupled to the condenser, and sub-cooling condensed liquid refrigerant in the sub-cooling conduit.

An evaporative cooling device may be provided. The device may comprise a plurality of rollers, a screen looped around the plurality of rollers, a motor coupled to at least one roller and configured to drive the at least one roller, a basin configured to hold a liquid within an interior of the basin, and wherein at least one roller is at least partially within the interior of the basin. The screen may travel into the basin and capture an amount of the liquid. As the liquid is drawn into an airstream feeding a heat rejection device, the liquid may evaporate, cooling the air. The cooled air may provide a more efficient heat rejection device.

A spraying device, for spraying water onto an outdoor device of an air conditioner, including a water tank to store water, a first water level sensor to detect the water at a first water level, a second water level sensor to detect the water at a second water level, a nozzle to spray the water onto the outdoor device, and at least one processor configured to perform control to: with the stored water not being sprayed: start spraying the water onto the outdoor device, based on the water being detected at the first water level by the first water level sensor and the water being detected at the second water level by the second water level sensor, and with the stored water being sprayed: stop spraying the water onto the outdoor device, based on the water not being detected at the second water level by the second water level sensor.
