Demand defrost

Abstract

A controller is configured to be operable for: triggering a defrost cycle when a gap between Control Temperature (CT) and Saturated Suction Temperature (SST) exceeds a defined threshold of an expected/learned gap between the Control Temperature (CT) and Saturated Suction Temperature (SST); following the defrost cycle, executing a machine learning process for a determined amount of time during which the controller learns a current expected/learned gap between the Control Temperature (CT) and Saturated Suction Temperature (SST); and averaging the current expected/learned gap with a previous expected/learned gap, which was machine learned by the controller following a previous defrost cycle, to thereby provide an average expected/learned gap usable by the controller as the previous expected/learned gap following the next defrost cycle.
