This cycle involves four key phases: evaporation, compression, condensation, and expansion. Evaporation: The refrigeration cycle begins in the evaporator with a low-pressure liquid refrigerant absorbing heat from its surrounding environment.

Air cooling. Cooling air could be passed through the cathode and/or through cooling plates between the cells. • Liquid cooling.
