This hot water supply relevant to heat pump and firing equipment have structure as previously described, therefore have following point.
The first, need to thaw operation when forming the evaporator surface formation frost of heat pump refrigerating circulation time, heating and hot water supply function must stop completely, have operated until thaw. In the time thawing operation, hot water can not be supplied, and indoor air temperature also decreases. If also carry out heating operation in the operation of thawing, heat will transfer to cold-producing medium from water-refrigerant heat exchanger, and therefore the temperature of recirculated water reduces, thereby causes indoor floor temperature to reduce.
The second, even can again carry out hot water supply and heating thawing after having operated, the hot water that make Heating Cyclic reach a normal level and supply reaches fixed temperature also needs a period of time.
The 3rd, for water-refrigerant heat exchanger of heating and separate for the water-refrigerant heat exchanger of hot-water supply, therefore installation process is comparatively complicated, and has increased manufacturing cost.
Another to the method that forms evaporator surface of heat pump refrigerating circulation and thaw is, utilizes coordinating evaporator surface blowing hot-air of electric heater and fan; Or adopt Electromagnetic Heating mode, utilize electromagnetic field to produce heat at the eddy current of evaporator body induction and make that evaporimeter is heating up to thaw.
