Résumé

All the time the reliability of motor is one of the important factors affecting the lifespan of compressor. It is particularly severe for motor in a R32 hermetic rotary compressor, which is cooled by discharge R32 at high pressure and temperature. This paper presents a method to obtain the 3-D temperature distribution of motor-refrigerant in a R32 hermetic rotary compressor. Fluid–solid coupling analysis method was used to simulate the heat transfer between refrigerant and motor. The clearance between motor rotor and stator, the influence of rotating balancer attached to rotor on the fluid field and the impact of heat insulation material on heat transfer are taken into account. The simulation results fit the experimental data well. The analytical conclusions would be useful for further understanding of heat transfer in motor, and also provide a guideline of designing and improving compressor for manufacturers.
