Four-way valve, four-way valve assembly, air conditioner and working method thereof

Abstract

The invention provides a four-way valve, a four-way valve assembly, an air conditioner and a working method thereof. The four-way valve comprises a valve body, a slider, a D pipe, an E pipe, an S pipeand a C pipe. All the D pipe, the E pipe, the S pipe and the C pipe communicate with the interior of the valve body. The slider is arranged in the valve body. A bypass pipe is connected between the Dpipe and the S pipe. The first end of the bypass pipe is connected to the peripheral wall of the D pipe. The second end of the bypass pipe is connected to the peripheral wall of the S pipe. A controlvalve is arranged on the bypass pipe. Through the four-way valve, reversing reliability can be improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a four-way valve, a four-way valve assembly, an air conditioner and a working method thereof. Background technique [0002] The electromagnetic four-way reversing valve, referred to as the four-way valve, is an important part of the heat pump air conditioner. Its main function is to use the relative movement between the valve core and the valve body to change the flow direction of the refrigerant, so that the heat pump air conditioner realizes the cooling mode. Switch between the heating mode and realize the heating and defrosting function to meet the user's demand for the heating capacity of the unit. [0003] The four-way valve is an important functional part of the heat pump air conditioner. If it fails, it will lead to the failure of important functions of the air conditioner, which will not only increase the difficulty of maintenance operations and maintenance costs...

AI Technical Summary

Problems solved by technology

[0003] The four-way valve is an important functional part of the heat pump air conditioner. If it fails, it will lead to the failure of important functions of the air conditioner, which will not only increase the difficulty of maintenance operations and maintenance costs, but also fail to meet the needs of users and reduce user satisfaction. degree, increasing the risk of complaints

This is related to the high and low pressure difference during the reversing process of the four-way valve and the length of the two ends of the slider, which will lead to the balance of the high and low pressure difference during the reversing process of the four-way valve, which cannot overcome the sliding resistance of the slider
