Air-cooled cold water or source pump are mainly made up of compressor, condenser, expansion valve, vaporizer.
1, compressor: in refrigeration plant, compressor is compressed into the gas of High Temperature High Pressure the refrigerant gas of low-temp low-pressure, then drains into air cooled condenser.
2, air cooled condenser: the effect of condenser is that the refrigerant superheat steam of the High Temperature High Pressure discharged by compressor is cooled to liquid or gas-liquid mixture, and cold-producing medium liberated heat within the condenser is taken away by extraneous cooling medium.
3, expansion valve: make condenser highly pressurized liquid throttling blood pressure lowering out, makes liquid refrigerant vaporize heat absorption under low pressure (low temperature).
4, vaporizer: the effect of vaporizer is to utilize liquid low temperature cold-producing medium the most easily to evaporate, is changed into steam and absorbs the heat of cooled medium, reaching the purpose of cooling.
5, four-way change-over valve: be served only for wind-cooling type heat pump unit, the mode of operation of power and energy handpiece Water Chilling Units, refrigeration mode conversion heats to heat pump or heat pump heats conversion to refrigeration mode.
The condenser of existing this air-cooled cold water or source pump is only with single cooling medium air, and the supercooling temperature of cold-producing medium can only be limited in 2～5c, heat exchanger effectiveness, and the efficiency of compressor still has the biggest optimization space.
