冷媒电加热器设计及在空调上的应用

Abstract

Abstract: In this paper, a new type of air-conditioner electric heater with compact structure, high heating efficiency, good sealing ability and safe operation is designed. The technical problem of poor performance at low temperature is solved, and the function of quick frost at low temperature is realized. A set of experimental verification methods suitable for the safety application of refrigerant electric heaters is summed up, through the safety experiments of a large number of sample machines in different working conditions and various abnormal conditions. The results show that after the application of the cold medium electric heater, the prototype can be controlled at about 4min~8min compared with the conventional defrosting time. After the completion of the frosting, the air outlet can get hot air above 40 degrees centigrade. The heat of low temperature is improved and the comfort is good.

Key words: Air conditioner, Refrigerant electric heater, Frosting, Safety application experiment, Comfort
