During heat pump system defrost, four-way valve switches to identical with process of refrigerastion therefore cold in main coolant loop Matchmaker's flow direction is identical as process of refrigerastion.Unlike, solenoid valve 7 is opened at this time, thus 6 heat release of storage heater, therefore can use storage Hot device 6 and case tube heat exchanger (the second heat exchanger) provide defrost institute calorific requirement jointly.Since accumulation of heat module participates in defrost process, also Hot water temperature in the second heat exchanger, which can be slowed down, reduces amplitude, improves client comfort of heat pump system during defrost.
From the above description, it can be seen that the heat pump system and heat pump system control method of the embodiment of the present disclosure have following technology At least one effect:
Defrost institute calorific requirement is provided jointly using the second heat exchanger and accumulation of heat module, increases defrost energy, improves defrost effect Rate is conducive to guarantee that defrost is clean, improves heat pump system reliability.
Slowing down hot water temperature in the second heat exchanger reduces amplitude, and it is comfortable to improve client of heat pump system during defrost Property.
Gas-supplying enthalpy-increasing is carried out to compressor in heating operations, the ability and efficiency of heating is improved, widens heating operation model It encloses.
Valve member in relative simplicity heat pump system improves the operational reliability of heat pump system.
Finally it should be noted that: above embodiments are only to illustrate the technical solution of the disclosure rather than its limitations;To the greatest extent Pipe is described in detail the disclosure referring to preferred embodiment, it should be understood by those ordinary skilled in the art that: still It can modify to the specific embodiment of the disclosure or some technical features can be equivalently replaced;Without departing from this public affairs The spirit of technical solution is opened, should all be covered in the claimed technical proposal scope of the disclosure.
