What type of pressure differential is suggested to have to properly adjust an overfeed evaporator?

To properly adjust an overfeed evaporator, a pressure differential of around 10 PSI is suggested. This value represents a balance that ensures the proper flow of refrigerant through the evaporator, optimizing the efficiency of the cooling process. A differential pressure that is too low may not adequately circulate the refrigerant, compromising the system's performance and heat exchange efficiency. Conversely, a higher differential may lead to excessive refrigerant flow, resulting in operational issues or potential damage to the system components.

The 10 PSI recommendation provides a safe operating range that enhances the evaporator’s performance while preventing potential malfunctions associated with improper pressure adjustments. In systems where precise control of refrigerant flow is critical, adhering to this suggested differential can help maintain a stable and efficient refrigeration cycle.
