摘要
在理论计算分析比较非共沸混合制冷剂R4 0 7C和R2 2的热力性能的基础上 ,试验了R4 0 7C替代R2 2的房间空调器性能。结果表明用R4 0 7C替代R2 2时 ,对现有的空调系统和生产设备无需作大的调整 ,还验证了R4 0 7C在蒸发器上存在温度滑移 ,并就进一步提高R4 0 7C房间空调器性能提出了建议。
The characteristic of circle was calculated by using R407C and R22. The characters of the household air-conditioner when R22 was replaced by R407C have been investigated by experiments. It shows that the air-conditioner system and the producing equipment of the refrigerant R407C don't need to adjust much. This paper proves the character of temperature glide of R407C by this experiment. The proposals on how to improve the performance of the R407C household air-conditioner have been put forward.
