Abstract

The invention provides an electric appliance box, a safety control method of the electric appliance box and an air conditioner adopting a combustible refrigerant. The electric appliance box comprises a box body (10), a detection device (20) arranged in the box body (10) and used for detecting the concentration of the combustible refrigerant in the box body (10), a flame-retardant gas source (30) with an outlet connected to the box body (10), and a flame-retardant gas control device (40) arranged at the outlet of the flame-retardant gas source (30) in a sealed mode and used for opening the outlet of the flame-retardant gas source (30) when the detection device (20) detects that the concentration of the combustible refrigerant exceeds the standard. By adopting the electric appliance box, the problem that the combustible refrigerant in the prior art is leaked into the electric appliance box and accordingly burned can be solved.

Description

technical field [0001] The invention relates to the field of air conditioner safety control, in particular to an electrical box, a safety control method thereof, and an air conditioner using a flammable refrigerant. Background technique [0002] R22, R410A and other refrigerants used in large quantities by existing air conditioners, dehumidifiers and other electrical appliances have a destructive effect on the atmospheric ozone layer and have a high greenhouse effect. They are refrigerants that need to be replaced, while R290 (propane), R32, etc. Some low-GWP refrigerants have been studied for use in refrigeration and dehumidification systems such as air conditioners and dehumidifiers to replace the currently widely used R22, R410A, and R134A refrigerants. However, R290, R32, etc. are flammable refrigerants, and electrical appliances using such flammable refrigerants have higher safety requirements. [0003] For electrical appliances that use flammable refrigerants, there i...
