Type of article: Article

Summary

DISCUSSES HEAT PUMP EVAPORATOR FEED CONTROL PERFORMED BY AN ELECTRONIC EXPANSION VALVE. DESCRIBES TESTS TO DEMONSTRATE THE INFLUENCE OF REFRIGERANT SUPERHEATING ON PERFORMANCE, THE COP AND THE THERMAL STABILITY OF THE EVAPORATOR FEED CONTROL SYSTEM. DEMONSTRATES HOW THE EXPANSION VALVE CONTROLS DISTURBANCES, AND HOW THE OCCURRENCE OF DISTURBANCES AFFECTS THE THERMAL STABILITY OF THE CONTROL SYSTEM.
