The invention discloses a compensation type double-source heat pump cold and hot air air-conditioner unit. The compensation type double-source heat pump cold and hot air air-conditioner unit particularly comprises a refrigeration system, a ventilation system and a compensation type water source system. The refrigeration system comprises a refrigerant circulation loop composed of a water source heat exchanger, a hot source side air-cooling heat exchanger, a use side air-cooling heat exchanger, a compressor and a four-way valve. The compensation type water source system comprises a hot source side refrigerating medium circulation loop formed by sequentially connecting a compensation surface cooler, a water source heat exchanger, a buried heat exchange coil pipe, a water pump and a compensation surface cooler electric valve in series, and a compensation surface cooler bypass electric valve is arranged on the hot source side refrigerating medium circulation loop. Through the cooperative operation of the refrigeration system, the ventilation system and the compensation type water source system, the six operation modes of ground source heating, air source heating, ground source refrigeration, air source refrigeration, defrosting operation and heat compensation operation of the air-conditioner unit are achieved, and the problem that enough heat cannot be provided for a long time in the prior art is effectively solved.
Description
technical field [0001] The invention relates to the technical field of heat pump air conditioners, in particular to 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, cools the indoor air, ...
