Cooling method and apparatus
First Claim
1. A cooling system located within an airstream, comprising:
- a filter frame with sides and an open center;
a screen mesh affixed to the sides of the filter frame and extending across the open center and located within an air stream;
at least one conduit for delivering water to said screen mesh; and
an electronic control unit to control water flow, the electronic control unit being in communication with an ambient air temperature sensor and a relative humidity sensor, the electronic control unit controlling delivery of a water mist or spray from the conduit commensurate with measurements of the ambient air temperature and relative humidity received from the air temperature sensor and the relative humidity sensor, the electronic control unit further controlling water delivery based on condenser liquid discharge line temperature and compressor running status.

Abstract
An apparatus and method to cool compressors, condensing coils, and similar devices. The compressor or condensing coil is cooled by the delivery of water, which may be ambient temperature or chilled. In one embodiment, the water is delivered to a mesh filter or screen via one or more mist spray nozzles. Water conduits may be integrated with the filter frame. The method to control the delivery of the water is designed to conserve water. The control circuit comprises a microcontroller device which contains programming that receives inputs, including but not limited to, outside ambient air temperature, condenser liquid line temperature, relative humidity and electric current, and uses said inputs to provide a stepwise level of control (“solenoid open time”) of water delivery commensurate with outside air temperature and relative humidity.
