Why does the compression-refrigeration cycle have a high-pressure side and a low-pressure side?


a.The pressure difference is the result of polar molecular alignment due to the intense magnetic field created by the compressor motor.


b.So the refrigerant can condense at a low pressure and temperature and evaporate at a high pressure and temperature


c.The pressure difference isn't intentionally created but is simply the result of circulating refrigerant within the compressor.


d.So the refrigerant can evaporate at a low pressure and temperature and condense at a high pressure and temperature
