REFRIGERATION SYSTEM EARLY ALARM

摘要

A refrigeration system monitoring and alarm system for alerting of a reduction in refrigerant level. The system includes a refrigerant monitoring vessel (10) having a refrigerant inlet (12) and a refrigerant outlet (14), the vessel being full of refrigerant during normal operations. The system also includes a refrigerant inlet line (16) connected to the refrigerant inlet, a refrigerant outlet line (18) connected to the refrigerant outlet and a sensor (20) for continually sensing a property related to the actual level of refrigerant in the refrigerant monitoring vessel. The sensor produces electrical signals related to the actual level of refrigerant. The system further includes a processor (22) which is electrically connected to the sensor (20) for receiving the signals and for determining the adequacy of the refrigerant level in the refrigerant monitoring vessel and an alarm output mechanism (24) for providing alarms (50, 52, 54) related to the level of the refrigerant in the refrigerant monitoring vessel.
