The operation principle of the full recuperation of heat earth source heat pump of the utility model dual-system screw type unit is as follows:
User side need freeze or freeze+during a kind of in domestic hot-water or heat or heat+these four kinds of patterns of domestic hot-water, second magnetic valve 7 of second shunt must not be in closed condition by electricity, and first magnetic valve 4 of first shunt that communicates with the user side water system gets the electric open mode that is in, the high-temperature high-pressure refrigerant gas that comes out from compressor 1 enters 2.1 condensations of first condensing unit and becomes high pressure liquid refrigerant, through the device for drying and filtering 3 and first magnetic valve 4, again through the gas-liquid two-phase mix refrigerant of first expansion valve 5 throttlings the becoming low-temp low-pressure, enter 6 evaporations of first evaporimeter and become low area overheat gas, return compressor 1, finish a kind of refrigeration cycle.Second magnetic valve 7, second expansion valve 8 and second evaporimeter 9 are not participated in kind of refrigeration cycle.
When user side only need freeze, cold-producing medium liberated heat in condenser 2 was all taken away by groundwater circle system; When user side needed refrigeration+domestic hot-water simultaneously, cold-producing medium liberated heat in first condensing unit 2.1 was taken away by the hot water supply system, was unnecessaryly then taken away by groundwater circle system if having.Under these two kinds of patterns, the heat that absorbs in first evaporimeter 6 all comes from the user side water system.User side water system backwater enters first evaporimeter 6 from user side return pipe interface 6.2, temperature reduces after 6 coolings of first evaporimeter, come out to enter user's room conditioning end-equipment from user side outlet pipe interface 6.1, and cold air is diffused into indoor with cooling through blower fan.
When user side only need heat, cold-producing medium liberated heat in condenser 2 was all taken away by the user side water system.User side water system backwater enters condenser 2, absorbs to come out to enter user's room conditioning end-equipment after the heat temperature raises, and hot gas is diffused into indoor to heat up through blower fan.When user side need simultaneously to heat+during the domestic hot-water, cold-producing medium liberated heat part in first condensing unit 2.1 is taken away by the hot water supply system, another part is then taken away by the user side water system.Under these two kinds of patterns, the heat that absorbs in first evaporimeter 6 all comes from groundwater circle system A.
When user side only needs the domestic hot-water, first magnetic valve 4 of first shunt must not be in closed condition by electricity, and second magnetic valve 7 of second shunt that communicates with groundwater circle system gets the electric open mode that is in, the high-temperature high-pressure refrigerant gas that comes out from compressor 1 enters condenser 2 condensations and becomes high pressure liquid refrigerant, through the device for drying and filtering 3 and second magnetic valve 7, again through the gas-liquid two-phase mix refrigerant of second expansion valve 8 throttlings the becoming low-temp low-pressure, enter 9 evaporations of second evaporimeter and become low area overheat gas, return compressor 1, finish a kind of refrigeration cycle.First magnetic valve 4, first expansion valve 5 and first evaporimeter 6 are not participated in kind of refrigeration cycle.Cold-producing medium liberated heat in second condensing unit 2.2 is taken away by hot water supply system's boiler, is unnecessaryly then taken away by groundwater circle system if having.The heat that absorbs in second evaporimeter 9 all comes from underground water circulation B system.
Below only be described, but can not be interpreted as it is restriction claim with regard to most preferred embodiment of the present utility model.The utility model not only is confined to above embodiment, and its concrete structure allows variation, as: as described in first expansion valve 5 and second expansion valve 8 also can be electric expansion valve; Described first evaporimeter 6 and second evaporimeter 9 also can be flooded evaporators; The concrete layout of two evaporimeters, condenser and compressors is variable; Deng.All various variations of being done in the protection domain of the utility model independent claims are all in the utility model protection domain.
