The necessity of superheat in a refrigeration system is determined by the type of metering device used.
Superheating in a refrigeration system is determined by the type of metering device used. When a system has a TXV metering device, superheating is crucial to ensure proper refrigerant flow and system efficiency. On the other hand, if the system has a fixed-orifice metering device, superheating is not necessary as the device itself regulates the refrigerant flow.
