Accompanying drawing 13 is the workflow diagram of the solidifying ice evaporator refrigeration of the present invention and the workflow diagram of domestic hot-water processed；Intelligence
Energy controller can open solidifying ice branch road first switch valve 18 and solidifying ice branch road second switch valve 19, close air-source branch road
First switch valve 16 and air-source branch road second switch valve 17, close air-conditioning heat exchanger controlled valve 8, opening hot water changes
Hot device controlled valve 9, open the first expansion valve 4, open the second expansion valve 6, open water pump of air conditioner 11, open hot water water pump 12,
Close hot-swappable fans 10, close frozen water water pump 20 and frozen water separator 21.Intelligent controller controls four-way valve 2 according to heating side
Formula operation can so form refrigeration and domestic hot-water's circulation loop processed, the HTHP come out from the exhaust outlet of compressor 1
Gaseous refrigerant flows into hot water heat exchanger 7 by hot water heat exchanger controlled valve 9, and hot water water pump 12 is constantly to hot water heat exchanger 7
The new water of middle injection with realize exchanged heat with high temperature and high pressure gaseous refrigerant, a part of high temperature and high pressure gaseous refrigerant is condensed into
High temperature high pressure liquid；Refrigerant is changed into low-temp low-pressure gas-liquid two-phase liquid after the throttling of the second expansion valve 6 and flows into air-conditioning again
In heat exchanger 5, water pump of air conditioner 11 is in running order therefore substantial amounts of heat exchange cooling occurs in air-conditioning heat exchanger 5 for refrigerant
Air conditioner water is simultaneously evaporated to low-pressure gas；Low-pressure gas returns by the first expansion valve 4, solidifying ice evaporator 13, check-valves 14 again
To compressor 1, heat exchange does not occur in solidifying ice evaporator 13.By this foregoing circulation, hot water heat exchanger 7 and air-conditioning change
Hot device 5 completes that after heat exchange refrigeration and domestic hot-water processed can be effectively completed, and realizes and reclaims condensation waste heat while refrigeration
The purpose of heating domestic hot water.When cooling load is smaller, intelligent controller can open frozen water water pump 20 and frozen water separator
21 coagulate the evaporation and heat-exchange of ice evaporator 13 to drive.
