Abstract : A refrigeration system monitor has been developed which will provide an early warning that a refrigeration or air-conditioning system is experiencing internal problems. The monitor separates non-condensable gases from the flowing refrigerant and provides an external signal when a significant amount of gases have been collected. The presence of these non-condensable gases indicates that one or more problems are developing, including incomplete evacuation, suction side leaks and compressor bearings operating in a boundary lubrication regime. The type of gas collected is indicative of the specific malfunction. This document describes procedures for routine maintenance of the monitor.
