ABSTRACT:
A refrigeration system is disclosed having a purge system with means for monitoring operation of the purge system and for taking corrective action in response to excessive purge system operation. Preferably, the monitoring means is a microcomputer control system for monitoring purge pump operation to determine if the purge pump has operated continuously for a period of time greater than a predetermined amount of time. If the purge pump has operated continuously for a period of time greater than the predetermined amount of time, then the microcomputer control system overrides normal purge pump operation and maintains the purge pump inoperative for a selected time period before attempting to resume normal operation. The microcomputer control system counts the number of consecutive times that normal purge pump operation is overridden and totally disables the purge system if the number of consecutive overrides exceeds a preselected number.
