Abstract
A defrost control system for a reverse cycle refrigeration system wherein the outdoor coil is defrosted as a function of the operation of a demand type control for initiating the defrost mode of operation. The control system further includes a means for monitoring the frequency of defrost cycles. If too frequent defrosting is detected then the demand system is overriden and subsequent defrosting occurs only after the heat pump has been operating in the normal heating mode of operation for a predetermined length of time.
