摘要
Abstract
In recent years,there have been many safety accidents at home and abroad involving R32 flammable refrigerant air conditioners,where improper installation and maintenance operations caused blockage on the high-pressure side,resulting in compressor explosions.Relying on the temperature measurement technology of inverter compressor windings,the explosion scenarios of R32 air conditioning systems under extreme conditions will be simulated and restored through experiments to obtain the motor winding and exhaust temperatures at the instant of compressor explosion.Based on the winding temperature measurement technology,the temperature difference ΔT parameter between the calculated value of winding temperature and the measured value of exhaust temperature is fitted.It is proved that the ΔT parameter can represent the degree of danger of explosion of the compressor operating under extremely dangerous conditions,providing a key determination index for the safety protection control of flammable refrigerant air conditioning systems.关键词
