Abstract:
A method of operating a refrigeration system is provided. The method includes activating an evaporator heater (306), monitoring a pressure differential within the refrigeration system (308), when the pressure differential reaches a predetermined value (310), deactivating the evaporator heater (312), and activating one or more evaporator fans (314), after deactivating the evaporator heater, to cause a thermostatic expansion valve to open.
