Summary

THE AUTHOR DESCRIBES A SCENARIO WHICH MAY BE COMMON IN A MULTI-EVAPORATOR SYSTEM SUCH AS THAT IN A NORMAL SUPERMARKET. TEMPERATURE CONTROL IS USUALLY BY LIQUID SOLENOID VALVES OPERATED BY CASE THERMOSTATS. COMPRESSORS ARE CONTROLLED BY SUCTION PRESSURESTATS. A SLOW LEAK IN A LIQUID LINE FLARED CONNECTOR MAY GRADUALLY BLEED THE SYSTEM OF REFRIGERANT RESULTING IN LONGER COMPRESSOR RUNNING TIME AND EVENTUALLY EVAPORATOR STARVATION, LACK OF OIL CIRCULATION, COMPRESSOR OVERHEATING AND FAILURE. A SUGGESTED MEANS OF DETECTING A REFRIGERANT LOSS BEFORE IT RESULTS IN DAMAGE USES A MICROPROCESSOR LIQUID LINE MONITOR WHICH IDENTIFIES THE PRESENCE OF VAPOUR. D.W.H.
