Summary

THE ELECTRIC EXPANSION VALVE REPLACES THE THERMOSTATIC EXPANSION VALVE BUT OPERATES, NOT ON A DEGREE OF SUPERHEAT, BUT ON THE BASIS OF DETECTING THE PRESENCE OF LIQUID REFRIGERANT. AS A NORMAL EXPANSION VALVE, THE SENSING THERMISTOR IS SITED AT THE LAST POINT IN THE EVAPORATOR WHERE LIQUID IS REQUIRED. BECAUSE THE VALVE IS A PURELY ELECTRICALLY OPERATED DEVICE, IT CAN BE USED FOR OTHER PURPOSES OF CONTROL. FOR INSTANCE, A SET TEMPERATURE CAN BE REGULATED, MAKING THE VALVE INTO A CONSTANT PRESSURE EXPANSION VALVE OR EVEN AN EVAPORATOR PRESSURE REGULATOR. THE ARTICLE EXPLAINS SUCH OPPORTUNITIES AND SUGGESTS A NEW ERA OF CONTROL IS NOW AVAILABLE. D.W.H.
