Abstract: Condenser control, systems, devices, and methods are described herein. One system includes a number of pressure sensors, wherein each of the number of pressure sensors is configured to sense a pressure associated with a condenser of a refrigeration system, a temperature sensor configured to sense an outdoor air temperature, and a controller configured to activate operation of a number of condenser fans and a number of split valves associated with the condenser based, at least in part, on the sensed outdoor air temperature upon a failure of each of the number of pressure sensors.

Abstract: A control apparatus and associated method for a refrigeration system are provided. The control apparatus includes sensors capable of detecting controlled refrigerator zone temperatures and superheat levels of refrigerant vapour exiting an evaporator. The control module receives input from the sensors, compares the input to a determined controlled refrigerator zone set point and a learned superheat level, and generates an output with respect thereto. In particular the output modulates an electronic evaporator pressure regulating (EEPR) valve between an open and a closed position in response to detecting abnormal operation of the thermostatic expansion valve or electronic expansion valve.
