The invention discloses a control method of a compensating type double-source heat pump heating / cooling air conditioning unit. The control method is implemented by the compensating type double-source heat pump heating / cooling air conditioning unit that specifically comprises a refrigerating system, a ventilating system, a compensating type water source system and an automatic control system; the refrigerating system comprises a refrigerant circulating loop composed of a water source heat exchanger, a heat source side air-cooled heat exchanger, a use side air-cooled heat exchanger, a four-way valve and a compressor; the compensating type water source system comprises a heat source side refrigerating medium circulating loop composed of a compensating surface air cooler, a water source heat exchanger, a buried heat exchange coil, a water pump, a compensating surface air cooler electric valve orderly connected in series, and a compensating surface air cooler bypass electric valve is arranged on the heat source side refrigerating medium circulating loop. The automatic control system controls cooperative operations of the refrigerating system, the ventilating system and the compensating type water source system to realize six modes of ground source heating, air source heating, ground source refrigerating, air source refrigerating, defrosting running and supplementary heating running of the unit; as a result, the defect that enough heat cannot be provided stably for a long time in the prior art is overcome.
Description
technical field [0001] The invention relates to the technical field of heat pump air conditioners, in particular to a control method for a compensation type dual-source heat pump cold and hot air air conditioner unit. Background technique [0002] At present, there are common ground source heat pump cooling and heating air units, which use the ground source to provide cold and heat sources for the cooling and heating operation of the cooling and heating fan units, and provide cold or hot air for air conditioning. [0003] Generally speaking, the ground source heat pump unit mainly consists of a compressor, a condenser, an evaporator, an expansion valve, and a four-way valve to form a circulation loop. In the cooling state, the high-pressure refrigerant vapor discharged from the compressor flows into the condenser through the four-way valve, the refrigerant vapor is condensed into liquid, enters the evaporator through the expansion valve, and absorbs heat in the evaporator, c...
