Reverse cycle refrigeration system

Claim 1

A METHOD OF OBTAINING STAGED COMPRESSION ON EITHER THE HEATING OR COOLING CYCLE OF A REFRIGERATION SYSTEM OPERABLE ON THE REVERSE CYCLE PRINCIPLE, SAID REFRIGERATION SYSTEM HAVING A COMPRESSOR, A FIRST HEAT EXCHANGE COIL, A SECOND HEAT EXCHANGE COIL, A FIRST EXPANSION MEANS ASSOCIATED WITH SAID FIRST HEAT EXCHANGE COIL, A SECOND EXPANSION MEANS ASSOCIATED WITH SAID SECOND HEAT EXCHANGE COIL, A REVERSING VALVE COUPLED BETWEEN SAID COMPRESSOR AND SAID COILS, AND AN EJECTOR ASSOCIATED WITH EACH OF SAID COILS, COMPRISING THE STEPS OF COMPRESSING THE REFRIGERANT, CONDENSING SAID REFRIGERANT IS ONE OF SAID COILS PASSING REFRIGERANT THROUGH THE EXPANSION MEANS ASSOCIATED WITH THE OTHER OF SAID COILS, EVAPORATING REFRIGERANT IN THE OTHER OF SAID COILS, PASSING REFRIGERANT THROUGH THE EJECTOR ASSOCIATED WITH THE OTHER OF SAID COILS TO EFFECT COMPRESSION OF REFRIGERANT AND DECREASE THE PRESSURE IN THE OTHER OF SAID COILS, PASSING SAID REFRIGERANT TO SAID COMPRESSOR TO REPEAT SAID FOREGOING CYCLE, AND SELECTIVELY MANIPULATING SAID REVERSING VALVE TO INTERCHANGE THE FUNCTIONS OF SAID COILS AND CAUSING THE EJECTOR ASSOCIATED WITH THE COIL THEN FUNCTIONING AS AN EVAPORATOR TO COMPRESS REFRIGERANT.
