Problems solved by technology

Although the check valve 2 prevents the return flow of the refrigerant when the air conditioner is running, when the air conditioner is restarted, the check valve causes a pressure difference between the refrigerant suction side and the refrigerant discharge side, resulting in the need to spend a lot of time to restart the air conditioner. start the air conditioner

Abstract

A device for switching refrigerant pipes of an air conditioner, comprising: a valve sleeve, which is installed at the position where the refrigerant discharge pipes of multiple compressors gather, the valve sleeve has a valve body space part, and the valve sleeve has a The upper side and the lower side include a first refrigerant inlet, a second refrigerant inlet, a refrigerant outlet, a bypass outlet, and a detour refrigerant outlet; a bypass pipe is used to connect the refrigerant outlet of the valve sleeve to all the refrigerant suction pipe of the compressor, so that the refrigerant discharged from each refrigerant discharge pipe of the compressor can be introduced into the refrigerant suction pipe of the compressor; the on / off valve is slidably installed on the valve In the valve body space part of the sleeve, so that the refrigerant discharged from the refrigerant discharge pipe can be selectively introduced into the refrigerant circulation pipe of the condenser or the bypass pipe; and the opening / closing valve driving device is installed in The valve sleeves and actuates the on / off valve.

Description

technical field [0001] The present invention mainly relates to an apparatus for switching refrigerant pipes of an air conditioner, and more particularly to a device capable of preventing refrigerant backflow even when the air conditioner is stopped, and by eliminating the gap between the refrigerant suction side and the refrigerant discharge side before restarting the air conditioner. A device for switching the refrigerant pipes of the air conditioner that can quickly restart the air conditioner due to the pressure difference between them. Background technique [0002] Generally, a refrigeration cycle of an air conditioner repeatedly performs a compression process, a condensation process, an expansion process, and an evaporation device. The refrigeration cycle includes: a compressor for compressing a low-temperature and low-pressure refrigerant to convert it into a high-temperature and high-pressure refrigerant; a condenser for condensing the high-temperature and high-pressu...
