The operation principle of the present invention：During refrigeration, refrigerant is compressed into the gas-liquid mixture of HTHP by compressor 1, now
The no power of four-way valve 2, refrigerant enters radiator 3 from first passage 16, and the water in radiator 3 absorbs the heat of refrigerant and temperature liter
Height, water enters cascade 12 from shower 36, and now refrigeration fan 13 is in running order, and refrigeration fan 13 blows away the heat in water
Amount so that water tank 11 is come back to after the coolant-temperature gage reduction in cascade 12, water tank 11 can carry out moisturizing by filling pipe 29,
When water level is too high by the spilling water of overflow pipe 31, time opening blowoff electromagnetic valve 32 is set to carry out blowdown according to system, also can hand
Dynamic to be discharged water by drainpipe 33, the water in water tank 11 is continually sent in the water pipe in radiator 3 by water pump 34, empty when winter
Mediate when state is heated, the water that non-freezing drainage valve 35 is allowed to dry in radiator 3 can be opened, prevent radiator 3 to be damaged by frost, from radiating
The refrigerant that device 3 is gone out has turned into the liquid of high pressure low temperature, is stored in after then absorbing the moisture in refrigerant by device for drying and filtering 4
In reservoir 5, liquid coolant becomes gaseous coolant by expansion valve 6, and now two-port valve 8 is not turned on, and refrigerant is through the 3rd check valve
21 change 7 into evaporation plate, because the pressure of the port of export of radiator 3 is higher than the pressure of the entrance point of the second check valve 20, therefore pass through
Refrigerant after 3rd check valve 21 will not be circulated by the second check valve 20, evaporation plate change water in 7 absorb refrigerant cold and
Temperature is reduced, and the blower fan of indoor set 15 brushes cold water and freeze, and changing 7 refrigerant from second channel 17 by evaporation plate enters the 3rd
Gas-liquid separator 10 is reached after passage 18, compressor 1 is returned, low pressure gauge 23 and high-pressure manometer 25 can pay close attention to sky at any time
Running status is adjusted, fluorine mouthful 24 or high pressure plus fluorine mouthful 26 can be added to be added by low pressure when cold medium shortage, also using low pressure
Plus fluorine mouthful 24 or high pressure add fluorine mouthful 26 to be vacuumized, while adding fluorine mouthful 24 and high pressure plus 26 vacuumizing effects of fluorine mouthful using low pressure
More preferably.
When heating, refrigerant is compressed into the gas-liquid mixture of HTHP by compressor 1, and now four-way valve 2 is powered, and first leads to
Road 16 is not turned on, and second channel 17 is turned on, and refrigerant changes 7 into evaporation plate, and the water that evaporation plate is changed in 7 absorbs the heat of refrigerant and warm
Degree rise, the blower fan of indoor set 15 brushes hot water and heated, and evaporation plate changes 7 refrigerant out into the liquid of high pressure low temperature, cold
Matchmaker passes through device for drying and filtering 4 and reservoir 5 through the second check valve 20, is changed into gaseous coolant in expansion valve 6, now two-port valve 8
Conducting, and the outlet pressures of the 3rd check valve 21 are higher than its import end pressure, therefore refrigerant will not circulate from the 3rd check valve 21,
Refrigerant arrives evaporator 9 through two-port valve 8, and refrigerant releases cold on evaporator 9, and it is in running order now to heat blower fan 14, will
Cold blows to outside, when the temperature is too low, meeting frosting on evaporator 9, and the temperature sensor 27 that now defrosts senses that temperature is too low,
By starting defrosting magnetic valve 22, a part of hot water in indoor set 15 is sprayed from defrosting hot-water line 41 by hot water outlet 44
Go out to pour the defrost on copper pipe 37, refrigerant enters gas-liquid separator 10 after evaporator 9, eventually passes back to compressor 1.
