Now people pay more attention to environmental issues, in many products are selected smart and environmentally friendly, such as water source heat pump, it can be said that its technology is very advanced, the use of renewable energy, energy saving effect is obvious of. Xiaobian here to introduce water heater heat pump water chiller how to refrigeration and heating? Water source heat pump water chiller First, the cooling circuit flow in the summer when the unit is in the cooling state, the compressor exhaust high temperature and pressure gas refrigerant through the four-way steering valve into the condensing heat exchanger. After condensing and exothermic, it becomes a high-pressure liquid refrigerant, enters the liquid storage tank through the check valve 1 and becomes a low-pressure liquid refrigerant via the throttle valve, enters the casing evaporator through the check valve 4, absorbs heat and evaporates into a low-pressure gas refrigerant, The gas-liquid separator and the four-way valve to the compressor suction port to complete the refrigeration cycle. Second, the heating circuit flow in winter when the unit in the heating state, the compressor outlet from the high temperature and high pressure refrigerant through the four-way valve into the heat exchanger tube condensate into high pressure liquid, and then through a one-way Valve 2 into the tank, the throttle valve into a low-pressure liquid refrigerant through the check valve 3 to the fin-type heat exchanger (that is, in the cooling process of the condenser) absorbs heat as a low-pressure vapor refrigerant, through Gas-liquid separator and four-way valve to the compressor inlet to complete the heating cycle.
