Hot gas defrosting. In the hot gas defrosting system, the refrigerant gas of the system is temporarily diverted through an alternate circuit, where the gas is compressed and heated. The hot gas is then directed to the evaporator, where it warms the surface and melts the accumulated ice. Once the defrosting process is complete, the system returns to its normal cooling mode. This method offers several advantages over other methods, such as energy savings, reduced defrosting times, and the ability to perform defrosting without interrupting the cooling process.
