Abstract

The invention discloses a control method of a high-stability heat pump system. The control method comprises the following steps that main valve control parameters are detected, and the opening degreeof a main electronic expansion valve is adjusted according to the main valve control parameters; auxiliary valve control parameters are detected, and the opening degree of an auxiliary electronic expansion valve is adjusted according to the auxiliary valve control parameters; and compressor control parameters are detected, and stopping of a compressor is controlled according to the compressor control parameters. According to the control method, the opening degrees of the related expansion valves and stopping of the compressor in the heat pump system can be controlled, then the flow of a refrigerant fluid is adjusted so that the compressor is prevented from running in a dangerous state, and the problems that the heat pump system is unstable in heating effect and the compressor is lost can be solved.

Description

technical field [0001] The invention relates to the field of control of heating systems, in particular to a control method of a high-stability heat pump system Background technique [0002] Heat pump systems are commonly used heating systems. The compressor compresses the refrigerant into a high temperature and high pressure fluid. After the refrigerant fluid flows out from the exhaust port of the compressor, it flows through the four-way valve to the high-efficiency tank, economizer and other devices for cooling, and then through the expansion valve and other throttling devices to reduce the pressure, and finally release heat in the evaporator. To achieve the heating effect, the refrigerant fluid then passes through the four-way valve and gas-liquid separator and other devices, and then returns to the compressor through the suction port of the compressor, completing a thermal cycle. The compressor is the core device of the heat pump system, which directly determines the h...
