Heat pump system, control method, device and equipment thereof and storage medium

The invention relates to a heat pump system, a control method, device and equipment thereof and a storage medium, and is applied to the technical field of heat exchange. The heat pump system, the control method, device and equipment thereof and the storage medium solve the problem that a sliding block of a four-way valve is jacked or the four-way valve is damaged caused by reverse pressure difference during reversing of the four-way valve in the related art. The heat pump system control method comprises the steps that the exhaust pressure of an exhaust pipe of a four-way valve in the heat pumpsystem and the suction pressure of an air suction pipe of the four-way valve are detected, if the heat pump system meets the preset operating condition, the pressure difference between the exhaust pressure and the suction pressure is obtained, and if the pressure difference is between the preset minimum value and the preset maximum value, the four-way valve is controlled to perform the reversingoperation. 本发明涉及一种热泵系统及其控制
