| 摘 要： | 分析了R22/R142b在高温空调系统中应用的可行性,实验研究了高温空调样机性能参数随制冷剂混合比变化的规律,确定了空调样机的最佳充灌量。实验表明:R22/R142b的质量比为6.6/3.4~7.0/3.0时,空调系统在较宽的环境温度范围(35℃—60℃)制冷量变化平坦,技术和经济性能理想,排气温度和压力在普通空调压缩机的安全范围;同时显示制冷剂充灌量为2.6kg左右时,空调样机的制冷运行性能较优。 |

| Abstract: | The paper theoretically analyzed the feasibility of the application of R22/R142b in high temperature air-conditioner system,and experimentally studied the variation of the running performance of the model air-conditioner for different mass fractions,the experiment also fixed the optimal refrigerant charge.The experiment demonstrated that the air-conditioner works well on a wide range of environment temperature from 35℃ to 60℃ when the mass fractions of R22/R142b range from 6.6/3.4 to 7.0/3.0,for the cooling capacities are relatively high and changes smoothly;and the EER are relatively ideal;both the exhaust temperature and the exhaust pressure are in the safe scope of common compressor used in air-conditioner during working;meanwhile,the air-conditioner used in the experiment runs fairly well in high temperature work conditions when the refrigerant charge is about 2.6kg. |
