Detection system, method, device and air conditioner

Abstract

The embodiment of the present invention discloses a detection system, including two solenoid valves arranged in the refrigerant circuit, a pressure sensor arranged at the discharge port of the compressor, and a controller electrically connected with the two solenoid valves and the pressure sensor , so that the controller can open each solenoid valve sequentially according to the refrigerant circuit in the air conditioner after receiving the start-up command, and judge whether refrigerant is generated according to the pressure value collected by the pressure sensor before each solenoid valve is opened. Leakage, so that it can be judged whether refrigerant leakage occurs in the refrigerant circuit section before the solenoid valve that is closest to the compressor exhaust port in the refrigerant circuit. The range of locations where the agent leaks. The application also provides a detection method, device and air conditioner.

Description

Technical field [0001] The present invention relates to the technical field of air conditioners, and more specifically, to a detection system, method, device and air conditioner. Background technique [0002] Air conditioner refrigerant leakage not only wastes electricity, but also shortens the service life of the air conditioner, and can seriously cause fire or explosion hazards. Therefore, it is necessary to detect whether the refrigerant leaks. [0003] At present, there are many methods for detecting whether there is a refrigerant leak in an air conditioner, but these detection methods can only determine whether the refrigeration system has a leak, but cannot determine the location of the system leak. [0004] Therefore, how to detect where the refrigerant has leaked has become an urgent problem to be solved. Summary of the invention [0005] The object of the present invention is to provide a detection system to detect the location where the refrigerant leaks. [0006] In order t...
