Heat Pump Control Valve

US Patent:
4346567, Aug 31, 1982
Filed:
Jan 31, 1980
Appl. No.:
6/117076
Inventors:
David H. Sniader - Winnetka IL
International Classification:
F25B 1300, G05D 2312
US Classification:
62160
Abstract:
A control system for regulating the flow of water to the condenser to maintain most effective loading of the compressor in a water-to-air heat pump arrangement. The system incorporates a temperature sensitive valve which has a thermal transfer contact with the refrigerant flowing through the heat pump compressor which upon sensing the heat in the refrigerant rising or falling correspondingly variably opens and closes the water line to the heat exchanger so as to maintain the temperature at the compressor within a predetermined range, and maintain proper loading on the compressor during heating and cooling cycles of the heat pump.
