It is connected to 2 exhaust outlet of the compressor by the ice-melt by-passing valve 4, is switched by the ice-melt triple valve 4, controls the inflation
Formula evaporator group 10 is connected in ice making heating mode with 2 air inlet of the compressor, controls the inflation type evaporator group 10
It is connected to 2 exhaust outlet of the compressor by the ice-melt by-passing valve 4 when ice-melt deices state；The inflation type evaporator group
10 are connected to the ice making dispenser 15 by the throttle valve 14；Liquid branch 300 is returned by going back to the connection heating major cycle of liquid valve 7 system
System and the hot-gas bypass ice-melt deice branch 200, and described time liquid valve 7 is in parallel with the expansion valve 9, and described time liquid valve 7 is temperature
Control valve is spent, temperature voltage input comes from the pipeline after the ice-melt by-passing valve 4 is connected to described time liquid valve 7, by the ice-melt
Port valve 4 be connected to described time liquid valve 7 after the temperature that sets of pipeline as 2 DEG C；When ice-melt deices state, from 2 row of the compressor
Gas port draws bypass high pressure hot gas, with the liquid refrigerant mixing evaporative cooling for coming from described time liquid valve 7 to 2 DEG C, passes through pressure
Power controls the ice-melt by-passing valve 4, so that ice-melt is deiced 10 pressure of inflation type evaporator group and remains 1 DEG C of saturation temperature institute of refrigerant
Corresponding saturation pressure makes the ice-melt deice 10 overall surface of inflation type evaporator group and keeps 1 DEG C of temperature, only makes the ice-melt
The ice for deicing 10 icing face of inflation type evaporator group uniformly melts on a small quantity, and slab slides automatically under the effect of gravity；Gaseous refrigerant
Agent condensation liquefaction in ice-melt deices inflation type evaporator group 10, ice-melt deice the condensed liquid refrigerant of process generation constant
Under pressure, through the throttle valve 14, liquid refrigerant can keep regime flow to automatically flow into another set heating major circulatory system
Inflation type evaporator in evaporate, be conducive to expansion valve 9 to the stability contorting of refrigerant flow, reduce ice-melt and deice process to ice making
The influence that refrigerant flow, temperature and pressure stability in major circulatory system operational process are heated when heating mode, also prevents height
Warm gas is directly entered the ice-melt and deices inflation type evaporator group 10, and the ice-melt is made to deice 10 part of inflation type evaporator group
Surface temperature is excessively high, big, the local ice-melt temperature difference of local thermal shock is big, excessive ice-melt, heat consumption are big.
In winter, the hot water that heat pump unit condenser 5 is heated can be by heat exchanger for heating；- 5 DEG C of environment above
At a temperature of, heat pump unit preferentially runs air-source heating mode, not only energy-efficient but also not water consumption；Under -5 DEG C or less environment temperatures,
Heat pump unit preferentially runs ice making heating mode, and heat pump unit had not only kept energy-efficient but also can lack water consumption, and heat pump can be greatly decreased
Unit warm season needs water inventory, and ice making heating mode by-product sorbet can arrange in addition or recycling treatment.
Evening paddy electricity operation ice making heating mode, heat pump unit ice making heating mode may be used in summer, heat pump ice maker group
The ice of production can be used for the energy saving cooling of ice-chilling air conditioning system at night；The hot water that condenser 5 is heated can then pass through cooling
Tower is to function of environment heat emission；And heat pump unit ice making heating mode can also directly freeze cooling work(as handpiece Water Chilling Units Effec-tive Function
Can, the inflation type evaporator group 10 is intake 12 DEG C, and water drenched temperature after the inflation type evaporator group 10 and is reduced to 7 DEG C to be gone again
Air conditioning terminal cooling, 12 DEG C of return water of air conditioning terminal are cooled down into the inflation type evaporator group 10 again；The heat that condenser 5 is heated
Water, then can be by cooling tower to function of environment heat emission.
Above-listed detailed description is illustrating for possible embodiments of the present invention, which is not to limit this hair
