Operation principle of the present invention: during refrigeration, refrigerant is compressed into the gas-liquid mixture of HTHP by compressor 1, now cross valve 2 no power, refrigerant enters radiator 3 from first passage 16, water in radiator 3 absorbs the heat of refrigerant and temperature raises, water enters cascade 12 from shower 36, now refrigeration fan 13 is in running order, refrigeration fan 13 blows away the heat in water, make to come back to water tank 11 after the coolant-temperature gage in cascade 12 reduces, water tank 11 carries out moisturizing by filling pipe 29, when water level is too high by overflow pipe 31 spilling water, blowdown is carried out according to Operation system setting time opening blowoff electromagnetic valve 32, also can manually be discharged water by drainpipe 33, water in water tank 11 is delivered in the water pipe in radiator 3 by water pump 34 continually, when winter air-conditioning be in heat state time, non-freezing drainage valve 35 can be opened and put water in dry radiator 3, radiator 3 is prevented to be damaged by frost, the refrigerant of going out from radiator 3 has become the liquid of high pressure low temperature, be stored in reservoir 5 then absorbed the moisture in refrigerant by device for drying and filtering 4 after, liquid coolant becomes gaseous coolant through expansion valve 6, now two-port valve 8 not conducting, refrigerant enters evaporation plate through the 3rd check valve 21 and changes 7, because the pressure of radiator 3 port of export is higher than the pressure of the second check valve 20 entrance point, therefore the refrigerant after the 3rd check valve 21 can not be circulated by the second check valve 20, the evaporation plate water changed in 7 absorbs the cold of refrigerant and temperature reduces, the blower fan of indoor set 15 brushes cold water and freezes, gas-liquid separator 10 is arrived after the refrigerant changing 7 through evaporation plate enters third channel 18 from second channel 17, return compressor 1, low pressure gauge 23 and high-pressure manometer 25 can pay close attention to running state of air conditioner at any time, add by low pressure fluoridize mouth 24 or high pressure fluoridize mouth 26 when cold medium shortage, low pressure fluoridize mouth 24 or high pressure fluoridize mouth 26 also can be utilized to vacuumize, utilize simultaneously low pressure fluoridize mouth 24 and high pressure fluoridize mouth 26 vacuumizing effect better.
When heating, refrigerant is compressed into the gas-liquid mixture of HTHP by compressor 1, now cross valve 2 is energized, first passage 16 not conducting, second channel 17 conducting, refrigerant enters evaporation plate and changes 7, the evaporation plate water changed in 7 absorbs the heat of refrigerant and temperature raises, the blower fan of indoor set 15 brushes hot water and heats, evaporation plate changes the liquid that 7 refrigerants have out become high pressure low temperature, refrigerant through the second check valve 20 through device for drying and filtering 4 and reservoir 5, gaseous coolant is become in expansion valve 6, now two-port valve 8 conducting, and the 3rd check valve 21 outlet pressures is higher than its entrance point pressure, therefore refrigerant can not circulate from the 3rd check valve 21, refrigerant arrives evaporimeter 9 through two-port valve 8, refrigerant releases cold on evaporimeter 9, now heat blower fan 14 in running order, cold is blown to outside, when the temperature is too low, meeting frosting on evaporimeter 9, 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 watered defrost on copper pipe 37 from defrosting hot-water line 41 by hot water outlet 44 ejection, refrigerant enters gas-liquid separator 10 after evaporator 9, finally get back to compressor 1.
