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。
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/ixed 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.
