What is the typical hot gas regulator pressure during defrost in an industrial refrigeration system?

In an industrial refrigeration system, the typical hot gas regulator pressure during defrost is around 90 PSIG. This pressure is crucial as it allows for adequate hot gas to be delivered to the evaporator or the area in need of defrosting. The hot gas is used to raise the temperature of the ice or frost on evaporator coils, facilitating the melting process and ensuring efficient operation of the refrigeration system.

Maintaining the correct hot gas pressure during defrost is essential for effective heat transfer and to prevent damage to the evaporator. If the pressure is too low, it might not provide sufficient heat, while excessively high pressure can lead to operational issues or equipment stress. Therefore, the 90 PSIG setting strikes a balance that meets the required operational demands for effective defrosting without compromising the system's integrity.
