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.

The system of the present disclosure reduces the temperature of any air conditioning condenser/radiator, either through retrofit or by original manufacturing. The system is connected to a water supply for pre-cooling ambient air drawn into the air conditioning unit by providing a misting spray of water that evaporates rapidly to cool the air conditioning condenser. The system has a water supply connection connected to the water supply, a water treatment assembly for treating aspects of the water supplied, and a water delivery assembly that receives clean water from the water treatment assembly and delivers the misting spray proximate the air conditioning unit. The system may be controlled by using a wireless technology such as a Z-wave or other type of wireless controller and one or more sensors.

An apparatus includes a housing that includes a front face, a rear face, a front-face cut out on the front face, a rear-face cut out on the rear face, a front-face screen to cover the front-face cut out, and a rear-face screen to cover the rear-face cut out. A box insertable between the front face and the rear face. The box includes a plurality of wicks behind the front face of the housing when the box is inserted in the housing. The box includes a water connection fitting coupled to the plurality of wicks through a controllable valve. The controllable valve has an open position and closed position.

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.

A natural cold-source heat-dissipation system for various data centers comprises an outdoor condenser (1), an indoor evaporator (2), and a thermal superconductive circulating device (3). An outlet of the outdoor condenser (1) is communicated with an inlet of the indoor evaporator (2) by means of the thermal superconductive circulating device (3), and an outlet of the indoor evaporator (2) is communicated with an inlet of the outdoor condenser (1) by means of a pipeline, so as to form a closed circulation system. The closed circulation system is filled with heat superconducting heat transfer working substance. The outdoor condenser (1) is an air-cooled condenser or a water-cooled condenser.

Systems, methods, and devices for evaporative cooling include one or more heat exchanger coils, one or more evaporative pads external to the one or more heat exchanger coils, and one or more nozzle assemblies external to the one or more evaporative pads. The one or more nozzle assemblies can be coupled to a supply of liquid and configured to provide the liquid to at least one of the one or more evaporative pads. A basin can be configured to collect a portion of liquid from the one or more evaporative pads, and an injector disposed between the supply of liquid and the one or more nozzle assemblies. The injector includes a first inlet coupled to the supply of liquid, a second inlet coupled to the basin, and an outlet coupled to the one or more nozzle assemblies.

A water-cooled split air conditioning system includes an indoor unit, an outdoor unit, and a plurality of connecting hoses. The outdoor unit includes an outdoor housing and a water cooling unit. The water cooling unit includes a pumping device, a top water collection basin, a fill material unit provided underneath the top water collection basin, a bottom water collection basin provided underneath the fill material unit, and a plurality of heat exchanging pipes provided in the bottom water collection basin and immersed in the cooling water. The cooling water collected in the bottom water collection tank is arranged to be guided to flow back into the top water collection basin. A predetermined amount of refrigerant is arranged to flow through the heat exchanging pipes to perform highly efficient heat exchanging process with the cooling water for lowering a temperature of the refrigerant.

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.
