Differences between standard conditions and air-conditioning conditions for screw compression refrigerators

Thread Content

I’d like to know what the differences are between the standard conditions and air-conditioning conditions for screw compression refrigerators What are the differences between installation and operation! According to the information available, standard operating conditions and air-conditioning operating conditions are the two types of conditions commonly used to compare the cooling capacity of compressors. 　　Standard operating conditions for domestic compressors: the working fluid is R12 or R22, with an evaporation temperature of –15°C, a suction temperature of 15°C, a condensation temperature of 30°C, and a subcooling temperature of 25°C. 　　Air-conditioning operating conditions for domestic compressors: the working fluid is R12 or R22, with an evaporation temperature of 5°C, a suction temperature of 15°C, a condensation temperature of 35°C (40°C according to some sources), and a subcooling temperature of 30°C. There are some things I don’t quite understand; is there any difference in terms of installation?
