Abstract

The invention discloses a control method and device of a four-way valve. The method comprises steps as follows: a starting request for indicating the running mode of an air conditioning unit is received, wherein the running mode refers to a refrigeration mode or a heating mode; a current mark position of a heat pump system to which the four-way valve belongs in the air conditioning unit is acquired and is determined at least based on historical working states of the four-way valve; according to the current mark position and the starting request, the four-way valve is controlled to be in a first working state or a second working state. By the aid of the control method and device of the four-way valve, the technical problem that the intelligent degree of reversing control on the four-way valve is lower in the prior art is solved.

Description

technical field [0001] The invention relates to the field of control, in particular to a control method and device for a four-way valve. Background technique [0002] At present, the four-way valves used in air-conditioning units (for example, heating and cooling air conditioners) are all driven by pressure difference, and the live coil of the pilot valve controls the action of the four-way valve. If the air-conditioning unit is in cooling mode, the four-way valve does not need to be powered on. , If the air conditioner unit is switched to heating mode, the coil of the four-way valve needs to be powered on for reversing, and the liquid hammer during the reversing process of the four-way valve will seriously damage the four-way valve. Especially during the standby or shutdown process of the air conditioner unit, the four-way valve generally does not change direction. Therefore, if the air conditioner unit switches modes when it is started next time, the air conditioner unit w...
