Summary

LOW THERMAL-POTENTIAL ENERGY CAN BE UTILIZED FOR A VAPOUR ABSORPTION REFRIGERATOR IN AN AIR CONDITIONING SYSTEM. OPERATION WITH LOW GRADE ENERGY, SUCH AS 333 TO 368 K (60 TO 95 DEG C) HOT WATER FROM SOLAR COLLECTORS IS POSSIBLE, HOWEVER, ITS COP IS LOWER THAN A VAPOUR COMPRESSION REFRIGERATOR. THIS PAPER DISCUSSES THE AVAILABILITY OF BOTH REFRIGERATORS WITH THE EXERGY LOSS IN THEIR HEAT SOURCE. THE ABSORBENT-REFRIGERANT COMBINATIONS INVESTIGATED IN THIS PAPER ARE AMMONIA-WATER AND WATER-LITHIUM BROMIDE. THE REFRIGERANT FOR THE VAPOUR COMPRESSION SYSTEM IS AMMONIA. THE EXERGY LOSS OF THE ABSORPTION REFRIGERATOR HAS BEEN CALCULATED FROM THE EXERGY DIFFERENCE BETWEEN THE INLET AND OUTLET OF THE HOT WATER SUPPLIED TO THE GENERATOR. THAT OF A COMPRESSION REFRIGERATOR HAS BEEN OBTAINED BY THE EXERGY DIFFERENCE BETWEEN THE INLET AND OUTLET OF THE VAPOUR IN THE STEAM TURBINE. THE EXERGY LOSS OF THE ABSORPTION REFRIGERATOR IS SMALLER THAN THAT OF THE COMPRESSION REFRIGERATOR.
