Below the know-why of this invention is elaborated from freezing and heating two kinds of operating modes:
One, cooling condition: air source heat pump unit and earth source heat pump unit are for being arranged in parallel, preferential operation earth source heat pump unit when freeze summer, by underground pipe 6, drawing cold from soil, to produce load side be the required cold water of load side condenser/evaporator 8, this operating mode take summer as main, mainly for past underground concurrent heating, for winter heating does heat deposit in advance, to alleviate unbalanced phenomenon of summer in winter.
(1), as shown in Figure 2, during unit operation, the refrigerant gas of low-temp low-pressure is after compressor 5 compressions, become the refrigerant superheat gas of HTHP, control valve DF1-1, control valve DF5-2 opens, overheated gas enters buried pipe end evaporative condenser 3, carry out heat exchange with cooling water, now cold-producing medium becomes cryogenic high pressure subcooled liquid by the gas of HTHP, control valve DF5-1, control valve DF7-1 opens, after expansion valve 9 step-downs, enter load side condenser/evaporator 8, refrigerant liquid carries out heat exchange in load side condenser/evaporator 8, heat absorption evaporation, control valve DF1-2 opens, the superheated vapor of low-temp low-pressure enters compressor 5 after gas-liquid separator 7, cold-producing medium is pressed in Fig. 2 and shown in arrow, is flowed and form refrigerant closed loop, so go round and begin again, thereby reach the object to indoor refrigeration.
By circulating pump, driving the cooling water of circular flow in underground pipe 6 is water or water-antifreezing agent mixed liquor, water-catalyst carrier mixed liquor, with cooling water after cold-producing medium heat exchange under circulating pump drives, constantly indoor heat is sent into the underground cold of getting in return, to continue indoor refrigeration.
(2), as shown in Figure 3, when the heat pump unit overload operation of local source causes temperature to reach setting protection, automatically switch to air source heat pump unit, by operation air source heat pump unit, meet user's needs that freeze.During unit operation, control valve DF1-1, control valve DF4-2 opens, the refrigerant superheat gas of HTHP enters air-source evaporative condenser 2, by means of blower fan to release heat in air, cold-producing medium becomes cryogenic high pressure subcooled liquid, control valve DF4-1, control valve DF7-1, control valve DF1-2 opens, after expansion valve 9 step-downs, enter load side condenser/evaporator 8, after evaporation endothermic, enter compressor 5, load side condenser/evaporator 8 is discharged into cold in end building, cold-producing medium is pressed in Fig. 3 and shown in arrow, is flowed and form refrigerant closed loop, so go round and begin again, thereby reach the object of refrigeration, meet user's needs that freeze.
Two, heating condition: under heating condition, solar still 1, air-source evaporative condenser 2, buried pipe end evaporative condenser 3, electric evaporator 4 are relations in parallel, regulate by automatic control unit.Under heating condition, preferentially move solar heat pump unit.
(1), as shown in Figure 4, during unit operation, control valve DF3-2, control valve DF2-2 open, and compressor 5 is constantly extracted low-temperature low-pressure refrigerant steam out from solar still 1, after compressor 5 compressions, are transformed into high pressure high temperature vapor.Controller DF2-1 opens, and high-temperature high-pressure refrigerant steam enters load side condenser/evaporator 8, emits amount of heat and is absorbed and be discharged in end building by the water in load side condenser/evaporator 8, thereby reach the object heating.Control valve DF7-1, control valve DF3-1 open, by the high pressure liquid refrigerant obtaining after 8 condensations of load side condenser/evaporator through expansion valve 9 throttlings, step-down, change low pressure refrigerant liquid into, low pressure refrigerant is in the interior evaporation of solar still 1, from solar water, absorb amount of heat, reduced the temperature of solar water.Cold-producing medium is pressed in Fig. 4 and is flowed and form refrigerant closed loop shown in arrow, thereby forms the circulation that heats of a solar heat pump unit.So go round and begin again, thereby reach the object heating, meet user and heat needs.
Wherein, solar still 1 is as heat collector throughout the year in thermal-arrest state, and the hot water condenser by being arranged in parallel with load side condenser/evaporator 8, can meet user's needs to health hot water throughout the year.At transition season when rich more than solar energy optical-thermal, control valve DF3-1, control valve DF3-2 open, solar thermal collector and underground pipe side form a train, utilize the circulating pump of underground pipe side that the waste heat of solar energy optical-thermal is proceeded to rock-soil layer accumulation of heat through buried pipe end evaporative condenser 3 circulations, for winter heating makes heat deposit, prevent unbalanced phenomenon of summer in winter.Have the user in underground heat storage pond, can also store by underground heat storage pond the waste heat of solar energy optical-thermal.
Solar energy heating adopts low form organic working medium as cold-producing medium self-loopa heat exchange, because solar energy optical-thermal and heat-absorbing medium are that the Temperature Difference Ratio solar energy optical-thermal of cold-producing medium and the temperature difference of water are twice above, cold-producing medium can absorb solar energy optical-thermal substantially, and when thermal-arrest meets heat supply needs, heat pump carries out heat exchange and promotes temperature.The configuration of solar energy heating area is only equivalent to conventional and 20~40% of water heat exchange, and the cost that solar energy optical-thermal is used is compared usual manner and reduced by 50~70%.
(2), night or successive cloudy days solar illuminating condition are bad can not meet user by operation solar heat pump unit and heat while requiring, automatically switch to air source heat pump unit, as shown in Figure 5, during unit operation, control valve DF2-1, control valve DF7-1, control valve DF4-1, control valve DF4-2, control valve DF2-2 open, other control valves are closed, and cold-producing medium is pressed in Fig. 5 and flowed and form refrigerant closed loop shown in arrow, thereby form the circulation that heats of an air source heat pump unit.So go round and begin again, thereby reach the object heating, meet user and heat needs.The workflow of air source heat pump unit is similar to solar heat pump unit, does not repeat them here.

(3), when outside air temperature is during lower than subzero 17 ℃ or the critical hoarfrost point of air humidity, there is obviously decay in air source heat pump unit, cannot meet load side and heat demand, automatically switch to earth source heat pump unit, by the water of circular flow in underground pipe from underground heat-obtaining and heat supply.As shown in Figure 6, during unit operation, control valve DF2-1, control valve DF7-1, control valve DF5-1, control valve DF5-2, control valve DF2-2 open, other control valves are closed, cold-producing medium is pressed in Fig. 6 and is flowed and form refrigerant closed loop shown in arrow, thereby forms the circulation that heats of an earth source heat pump unit.So go round and begin again, thereby reach the object heating, meet user and heat needs.The workflow of earth source heat pump unit is similar to solar heat pump unit, does not repeat them here.
(4), for open air without underground pipe engineering thereby do not possess the user of operation earth source heat pump unit condition, automatically switch to electrical heating heat pump unit.As shown in Figure 7, during unit operation, control valve DF2-1, control valve DF7-1, control valve DF6-1, control valve DF6-2, control valve DF2-2 open, other control valves are closed, cold-producing medium is heated in electric evaporator 4, evaporation endothermic, and press mobile formation refrigerant closed loop shown in arrow in Fig. 7, thus form the circulation that heats of an electrical heating heat pump unit.So go round and begin again, thereby reach the object heating, meet user and heat needs.
