The company develops a control method for the compensated double-source heat pump chiller-heater unit, which is realized by the compensated double-source heat pump chiller-heater unit, including the refrigeration system, ventilation system, compensated water source system and automatic control system, the refrigeration system comprises a refrigerant circulation circuit consisting of a water source heat exchanger, an air-cooled heat exchanger, a side water heat exchanger, a four-way valve and a compressor, the compensation type water source system includes the heat source side-load refrigerant circulation circuit which is connected in series with the electric valves of the compensation surface cooler, the water source heat exchanger, the ground heat exchange coil, the water pump and the compensation surface cooler, and a compensation table Cooler by-pass electric valve is arranged on the heat source side-loading refrigerant circulation circuit. The automatic control system controls the refrigeration system, the ventilation system and the compensation water source system to cooperate the operation, realizes the unit’s ground source heating, the air source heating, the ground source cooling, the air source cooling, defrosting operation and the supplementary heat operation six modes, an effective solution to the problem of providing sufficient heat in a long-term stable manner in the prior art.
