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
