A kind of working principle of pump type heat evaporative condenser water chiller-heater unit of the utility model is, when cooling in summer, refrigeration system
The refrigerant for high temperature and pressure of uniting is entered in finned heat exchanger 5 by refrigerant inlet pipe 1, and it is cold to become cryogenic high pressure by air-cooled heat exchange
Matchmaker, then entered in plate heat exchanger 9 by refrigerant outlet pipe a8, it exchanges heat again by evaporative condenser and becomes more cryogenic high pressure refrigerant, then
Refrigeration system throttling set is sent by refrigerant outlet pipe b11.During being somebody's turn to do, the air entered from air inlet is successively sprayed by bottom
Shower device and the sprinkling cooling of top spray device form that humidity is larger, the lower cold waste vapour of temperature, and cold waste vapour rises through fin
Formula heat exchanger, in finned heat exchanger refrigerant carry out it is cold and hot exchange, reduce refrigerant temperature.
When winter heats, heating system enters the refrigerant of low-temp low-pressure in finned heat exchanger by refrigerant inlet pipe 1, warp
The heat of air-cooled heat exchange absorption surrounding air is crossed without cutting steam, then is entered by refrigerant outlet pipe a and absorbs week in plate heat exchanger
Heat in weiqi minor league's glycol water, the low-pressure low-temperature refrigerant gas being vaporized are entered in compressor by refrigerant outlet pipe b, pass through pressure
The refrigerant gas of high temperature and pressure is formed after the compression of contracting machine.During being somebody's turn to do, the air entered from air inlet is successively sprayed by bottom
Shower device and the sprinkling cooling of top spray device form that humidity is larger, the lower cold waste vapour of temperature, but the temperature of the cold waste vapour is high
The refrigerant temperature in finned heat exchanger, humidity is lower than the cold waste vapour of summer, therefore low-temp low-pressure refrigerant passes through finned heat exchanger
Heat of vaporization vaporization is constantly absorbed from air-source, is entered back into plate heat exchanger, and heat of vaporization vapour is absorbed from ethylene glycol water
Change, two heat exchangers collective effect, to guarantee that machine unit in winter normally heats.
By test, the cooling in summer efficiency of the utility model pump type heat evaporative condenser water chiller-heater unit is more routinely evaporated cold
Solidifying water chiller-heater unit raising 10% or so, it is energy-efficient.
