REFRIGERANT FLOW CONTROL BY AN ELECTRICALLY DRIVEN EXPANSION VALVE IN REFRIGERATION SYSTEMS.

Author(s) : YASUDA H., ISHIBANE K.

Summary

REFRIGERANT FLOW CONTROL BY AN ELECTRICALLY DRIVEN EXPANSION VALVE WAS STUDIED BOTH THEORETICALLY AND EXPERIMENTALLY. THE EVAPORATOR IS SUPPLIED IN SUCH A WAY THAT CONTROLLED SUPERHEAT IS PROVIDED. AS A CONTROL ALGORITHM, THE PROPORTIONAL-INTEGRAL CONTROL PROCEDURE WAS USED. THE STABILITY OF THE CONTROL LOOP WAS ANALYZED THEORETICALLY IN ORDER TO CLARIFY STABILITY CONDITIONS. THE TESTING OF THE EVAPORATOR WAS CARRIED OUT WITH AN EXPANSION VALVE CONTROLLED BY A STEPPED MOTOR. IT WAS CONFIRMED THAT THE THEORETICAL ANALYSIS IS SUFFICIENTLY VALID FOR EXPLAINING TEST RESULTS. REFRIGERANT FLOW COULD BE CONTROLLED EFFICIENTLY WITH ELECTRICALLY DRIVEN CONTROL VALVES.
