Abstract

The invention discloses a four-tube three-way valve improved by utilizing a four-way valve of an air conditioner. According to the scheme, the four-tube three-way valve improved by utilizing the four-way valve of the air conditioner is characterized in that a D tube is a high-pressure refrigerant supplying tube, and an S tube, a C tube and an E tube serve as an air inlet tube and an air outlet tube for a refrigerant. The invention provides the four-tube three-way valve replacing an existing electromagnetic three-way valve.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration engineering, and in particular relates to a four-pipe three-way valve improved by using a four-way valve to increase the air-conditioning function and waste heat utilization system. Background technique [0002] Existing hot water air conditioning products mainly rely on the addition of solenoid valves in the refrigerant circulation loop, so as to obtain more functional modes than heat pump air conditioners or air source water heaters. Due to the many functions, a three-way solenoid valve is required. The three-way solenoid valve not only has the function of reverse conduction, but also one of the three pipes and any one of the other two pipes have the function of mutual transposition conduction. The existing problems are as follows: 1. It is easy to cause the transposition to fail, or the transposition is not in place; 2. The reliability is poor, and it is easy to leak...
