Abstract

The invention provides a control method of a heat pump air conditioner and the air conditioner. The control method of the heat pump air conditioner comprises the following steps of starting the heat pump air conditioner to release heat by utilizing an indoor unit of the heat pump air conditioner; detecting working condition parameters of the heat pump air conditioner; judging whether a working condition parameter of the heat pump air conditioner meets a preset extreme working condition; and if so, limiting the opening adjustment range of an electronic expansion valve of the heat pump air conditioner to be smaller than or equal to a preset adjustment limit value. According to the scheme, under the extreme working condition that the opening degree of the electronic expansion valve has greatinfluence on the exhaust temperature, large fluctuation of the exhaust temperature caused by excessive adjustment of the electronic expansion valve is avoided, and stable operation of a heat pump system is guaranteed.

Description

technical field [0001] The invention relates to air conditioning control, in particular to a control method of a heat pump air conditioner and the air conditioner. Background technique [0002] As the requirement for energy efficiency of air conditioners increases, electronic expansion valves are used as throttling devices for refrigeration systems in the prior art. The electronic expansion valve can realize variable flow and throttling according to the actual condition of the air conditioner, so as to meet the requirements of improving the energy efficiency and comfort of the air conditioner. [0003] figure 1 It is a schematic diagram of an air conditioner heat pump system in the prior art. In the heating mode, the air conditioner uses the heat pump principle to supply heat absorbed from the outside to the room. That is to say, the reversing valve 140 is turned to the working position of the heat pump, and the high-pressure refrigerant vapor discharged from the compress...
