OBSERVATIONS ON REFRIGERANT FLOW CONTROL IN SOLAR BOOSTED HEAT PUMPS.
Author(s) : DIXON C. W., CHARTERS W. W. S., CHANDRA S.
Summary
PROBLEMS CAN ARISE FROM THE CONTROL OF THE REFRIGERANT FLOW IN THE EVAPORATOR OF A SOLAR-BOOSTED HEAT PUMP. BECAUSE OF THESE PROBLEMS, THE HEAT PUMP OPERATION IS LESS EFFICIENT. THIS WAS STUDIED IN THE LABORATORY. THE RESULTS OF THESE EXPERIMENTS SHOW THE DISPLACEMENT OF THE SATURATED/SUPERHEATED TRANSITION POINT IN THE EVAPORATOR WHICH INFLUENCES THE CONTROL OF THE REFRIGERANT FLOW. THE STABLE AND UNSTABLE STATES, WHICH EXIST WHEN A THERMOSTATIC EXPANSION VALVE IS USED FOR CONTROLLING THE LIQUID REFRIGERANT FLOW, WERE IDENTIFIED.
