Abstract
Systems and methods are provided and include a case controller for a refrigeration case of a refrigeration system. The case controller is configured to: determine an evaporator saturated suction temperature (SST) of an evaporator of the refrigeration case; control an evaporator pressure regulator of the refrigeration system based on a comparison of the evaporator SST with an evaporator saturated suction temperature (SST) setpoint; receive an air temperature value from an air temperature sensor associated with the refrigeration case; determine whether the air temperature value is within a predetermined range of an air temperature setpoint; and adjust the SST setpoint in response to the air temperature value being outside of the predetermined range of the air temperature setpoint.
