摘　　要：本文提出了一种结构紧凑、加热效率高、密封性好、运行安全的新型空调冷媒电加热器设计,解决了低温制热时性能差的技术问题,实现了低温下迅速化霜的功能。通过大量试制样机在不同工况和各种异常情况下的安全实验,总结出一套适合冷媒电加热器安全应用的实验验证方法。研究结果表明,样机应用冷媒电加热器后,相比常规除霜时间可控制在4min～8min左右,化霜完成后出风口可以马上得到40℃以上的热风,低温制热量得到提升,舒适性好。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 40degrees centigrade.The heat of low temperature is improved and the comfort is good.
