分析了高、低压混合制冷剂的入口压力、温度、组分的摩尔分率对流程制冷剂流量、压缩机功耗、冷却水的冷却量及丙烷预冷量的影响 .利用所编制的计算机软件计算了这些参数对流程性能的影响 .计算结果表明 ,制冷剂流量受高压制冷剂的压力和温度以及混合制冷剂中甲烷的摩尔分率影响较大 ;压缩机功耗受高压制冷剂的温度、低压制冷剂的压力及混合制冷剂中甲烷的摩尔分率影响较大 ;冷却水的消耗量受低压制冷剂的压力及混合制冷剂中甲烷的摩尔分率影响较大 ;丙烷预冷量受混合制冷剂中甲烷的摩尔分率影响较大 .
The effects of inlet pressure, temperature and molar fraction of components on the flow of refrigerant, the power consumption of the compressor, the cooling capacity of the cooling water and the pre-cooling capacity of propane were analyzed.Using the computer software The results show that the refrigerant flow rate is greatly affected by the pressure and temperature of the high pressure refrigerant and the molar fraction of methane in the mixed refrigerant.The power consumption of the compressor is affected by the temperature of the high pressure refrigerant, The pressure of low pressure refrigerant and the molar fraction of methane in the mixed refrigerant are greatly affected; the consumption of cooling water is greatly affected by the pressure of the low pressure refrigerant and the molar fraction of methane in the mixed refrigerant; the pre-cooling capacity of the propane is affected by mixing The molar fraction of methane in the refrigerant has a greater impact.
