Abstract

The present invention provides a four-way valve reversing method. When a four-way valve is required for reversing, a pressure difference of a fluid flowing to the four-way valve is detected if meets requirements for four-way valve reversing; if does not, the pressure difference is adjusted to be within a preset pressure difference of the four-way valve, thereby enabling a reversing function of the four-way valve to be stable. According to the four-way valve reversing method, when the four-way valve is required for reversing, if the pressure difference is not within the preset pressure difference range of the four-way valve, the pressure difference can be increased or decreased to be within the preset pressure difference of the four-way valve, thereby enabling switching of refrigerating and heating functions of an air conditioner to be stable and raising product quality. Meanwhile, a four-way valve reversing device and an air conditioning system are also provided.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a four-way valve reversing control method, a four-way valve reversing control device and an air conditioning system. Background technique [0002] Air conditioning is air conditioning (air conditioning), which refers to the process of adjusting and controlling the temperature, humidity, cleanliness, speed and other parameters of the ambient air in a building / structure by artificial means. Generally include cold source / heat source equipment, cold and hot medium transmission and distribution system. [0003] As the relevant theoretical and practical research becomes more and more mature, the research on various components in the refrigeration system is also in-depth. For the four-way valve, the main function is to control the cooling and heating of the system through reversing. [0004] At present, the reversing control of the four-way valve is generally "direct power-on ...
