An air blowing from an outdoor unit passes through a vaporization filter installed to face an air outlet of an outdoor unit. The working water W is dropped from a water supply pipe above the vaporization filter, and the working water W flowing down from a filter constituent plate is collected in a water storage tank. The working water W is supplied to the water supply pipe by using a water supply pump. The working water W is circulated between the water storage tank, the water supply pipe, and the vaporization filter. The air blowing discharged from the outdoor unit and passed through the vaporization filter is deprived of the heat of vaporization, and the temperature of the air blowing from the outdoor unit exhaust cooling device is lowered.

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 adiabatic cooling system includes a condenser coil and one or more adiabatic pads positioned such that intake air for the adiabatic cooling system passes through the pads prior to contacting the condenser coil. The adiabatic cooling system includes a vibration device attached to each adiabatic pad. A controller is communicatively coupled to the vibration device for each of the adiabatic pads. The controller determines that cleaning of the adiabatic pads is needed. In response to detecting cleaning is needed, the controller causes the vibration device attached to each adiabatic pad to vibrate, thereby causing debris in the one or more adiabatic pads to become loosened and/or removed from the adiabatic pads.

An evaporative cooling device for a refrigeration system includes one or more heat exchanger coils, a first moisture panel, a second moisture panel, a first nozzle array, a second nozzle array, a moisture sensor, and a controller. The first moisture panel and the second moisture panel are separated by a distance and disposed external to the one or more heat exchanger coils. The first nozzle array is disposed external to the first moisture panel and the second nozzle array is disposed external to the second moisture panel. The first nozzle array and the second nozzle array are configured to provide an atomized spray of electrostatically charged droplets. The moisture sensor is configured to provide a signal representative of a moisture level. The controller is configured to receive the signal representative of the moisture level and control a supply of water.

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.
