EVALUATING REVERSING VALVE PERFORMANCE IN HEAT PUMP SYSTEMS.

Author(s) : KRISHNAN R. R.

Summary

THE CONCEPT USED CONSIDERS THE COMPRESSOR AND THE REVERSING VALVE AS A COMBINED UNIT IN A HEAT PUMP SYSTEM. USING A CALORIMETER SETUP, THE CHANGES IN PERFORMANCE OF THIS COMBINED UNIT OF COMPONENTS CAN BE STUDIED AT VARIOUS INLET AND OUTLET CONDITIONS. IT IS SHOWN HOW THE REVERSING VALVE HAS LESS OF AN EFFECT ON SYSTEM PERFORMANCE IN COMPARISON TO ITS EFFECT ON THE COMPRESSOR BY ITSELF. ONE VALVE THAT WAS TESTED SHOWED A DEGRADATION OF ABOUT 5% IN A SYSTEM, WHEREAS IT DROPPED THE PERFORMANCE OF THE COMPRESSOR ALONE BY ABOUT 8%.
