Abstract
A defrost cycle control assembly includes a first sensor that is configured to measure a temperature adjacent a top portion of an outdoor heat exchanger of a heat pump, a second sensor that is configured to measure a temperature adjacent a bottom portion of the outdoor heat exchanger, and a third sensor that is configured to measure an ambient temperature. Further, the defrost cycle control assembly includes a controller that is configured to initiate a defrost cycle of the heat pump based on the temperature adjacent the top portion and the ambient temperature when said temperatures indicate formation of frost at the top portion of the outdoor heat exchanger where the first sensor is disposed. The controller is configured to terminate the defrost cycle when the temperature at the bottom portion reaches a termination temperature which indicates that the frost on the outdoor heat exchanger has melted.
