Specific works process of the present utility model:
Process of refrigerastion, four-way change-over valve 2 does not power on, its operation principle is: after cold-producing medium compresses by compressor 1, output to the A channel of four-way change-over valve 2, by after the B passage of four-way change-over valve 2, the flow direction of cold-producing medium is divided into two-way again, and the water source evaporimeter 3 of leading up to reduces the temperature of cold-producing medium, the domestic water of water tank a91 is heated to assigned temperature simultaneously, then lowers the temperature for the second time through electric expansion valve a51; The air-source evaporimeter 4 of separately leading up to dispels the heat, lower the temperature for the second time by electric expansion valve b52 again, cold-producing medium after cooling is intersected in a road, then absorb heat in water source condenser 7 through filter 6, the coolant-temperature gage of water tank b92 is reduced, cold-producing medium after intensification is finally got back to the D passage of four-way change-over valve 2, after return compressor 1 through the C-channel of four-way change-over valve 2 to gas-liquid separator 8 again.
In process of refrigerastion, when make domestic water in water tank a91 be heated to assigned temperature by water source evaporimeter 3, close electric expansion valve a51, cold-producing medium just can only utilize air-source evaporimeter 4 to dispel the heat, its operation principle is: after cold-producing medium compresses by compressor 1, output to the A channel of four-way change-over valve 2, then cold-producing medium is sent to air-source evaporimeter 4 by the B passage of four-way change-over valve 2 and dispels the heat, the temperature of cold-producing medium is reduced, cold-producing medium is lowered the temperature for the second time by electric expansion valve b52 more afterwards, then absorb heat in water source condenser 7 through filter 6, make the b92 coolant-temperature gage of water tank continue to reduce, cold-producing medium after intensification is finally got back to the D passage of four-way change-over valve 2, after return compressor 1 through the C-channel of four-way change-over valve to gas-liquid separator 8 again.
Heating process, four-way change-over valve 2 powers on, its operation principle is: after cold-producing medium compresses by compressor 1, output to the A channel of four-way change-over valve 2, then cold-producing medium is sent to water source condenser 7 by the D passage of four-way change-over valve 2 and dispels the heat, the temperature of cold-producing medium is reduced, the water of heating water tank b92 simultaneously, cold-producing medium after cooling is by after filter 8, the flow direction of cold-producing medium is divided into two-way, the electric expansion valve a51 of leading up to lowers the temperature for the second time, absorb heat through water source evaporimeter 3 again, the electric expansion valve b52 of separately leading up to lowers the temperature for the second time, absorb heat through air-source evaporimeter 4 again, cold-producing medium after the intensification Cheng Yilu that crosses, then pass through the B passage of four-way change-over valve 2, return compressor 1 through the C-channel of four-way change-over valve 2 to gas-liquid separator 8 again.
In heating process, four-way change-over valve 2 powers on, when the water at low temperature of water tank a51 can not be absorbed heat from water source evaporimeter 3 for cold-producing medium, and air themperature is while making cold-producing medium absorb heat from air-source evaporimeter 4 compared with high energy, close electric expansion valve a51, its operation principle is: after cold-producing medium compresses by compressor 1, output to the A channel of four-way change-over valve 2, then cold-producing medium is sent to water source condenser 7 by the D passage of four-way change-over valve 2 and dispels the heat, the temperature of cold-producing medium is reduced, the water of heating water tank b92 simultaneously, cold-producing medium after cooling is lowered the temperature to electric expansion valve b52 for the second time through filter 6, then absorb heat through air-source evaporimeter 4, finally by the B passage of crossing four-way change-over valve 2, return compressor 1 through the C-channel of four-way change-over valve 2 to gas-liquid separator 8 again.
In heating process, four-way change-over valve 2 powers on, when the water temperature of water tank a51 is absorbed heat from water source evaporimeter 3 for cold-producing medium compared with high energy, and air themperature is lower can not make cold-producing medium absorb heat from air-source evaporimeter 4 time, close electric expansion valve b52, its operation principle is: after cold-producing medium compresses by compressor 1, output to the A channel of four-way change-over valve 2, then cold-producing medium is sent to water source condenser 7 by the D passage of four-way change-over valve 2 and dispels the heat, the temperature of cold-producing medium is reduced, the water of heating water tank b92 simultaneously, cold-producing medium after cooling is lowered the temperature to electric expansion valve b51 for the second time through filter 6, then absorb heat through water source evaporimeter 3, finally by the B passage of crossing four-way change-over valve 2, return compressor 1 through the C-channel of four-way change-over valve 2 to gas-liquid separator 8 again.
