REFRIGERATING SYSTEMS USING LOW PRESSURE RECEIVERS.

Summary

THE LOW PRESSURE RECEIVER REFERRED TO IS A VESSEL INSERTED BETWEEN EVAPORATOR OUTLET AND COMPRESSOR SUCTION, IN WHICH LIQUID REFRIGERANT FROM THE CONDENSER IS IN HEAT EXCHANGE WITH, FIRST, THE VAPOUR DEPARTING TO SUCTION AND, SECOND, A POOL OF EXCESS LIQUID RETURNED FROM THE EVAPORATOR. IN ADDITION THERE IS SUFFICIENT VOLUME TO ALLOW THE ENTIRE EVAPORATOR CHARGE TO BE HELD WITHOUT WET RETURN TO THE COMPRESSOR. THE SYSTEM WAS DEVELOPED TO MEET THE NEED FOR RELIABLE AUTOMATIC OPERATION OF FLUOROCARBON REFRIGERANT PLANTS ON LOW TEMPERATURE COLD STORE AND FREEZING DUTIES. ITS SUCCESS IS DEMONSTRATED ON A 2 STAGE DESIGN IN WHICH AN ADDITIONAL ECONOMISER SECTION IS ADDED AND A COMPARISON IS DRAWN WITH A CONVENTIONAL AMMONIA SYSTEM. AN ADDED ADVANTAGE OF THE SYSTEM IS THAT REVERSE CYCLE DEFROSTING CAN BE USED WHICH REDUCES BOTH OPERATING COSTS AND DEFROST TIME COMPARED WITH ELECTRIC DEFROST SYSTEMS. D.W.H.
