Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
202 words
AN EVAPORATOR CONSTRUCTION FOR USE IN A REFRIGERATION SYSTEM FOR COOLING A LIQUID HEAT EXCHANGE MEDIUM BY PLACING SAID MEDIUM IN HEAT EXCHANGE RELATION WITH ECAPORATING REFRIGERANT, SAID EVAPORATOR COMPRISING: (A) SHELL MEANS DEFINING AN EVAPORATING REGION ADAPTED TO CONTAIN A QUANTITY OF LIQUID HEAT EXCHANGE MEDIUM; (B) SHELL MEANS DEFINING A STORAGE VESSEL ADAPTED TO CONTAIN A QUANTITY OF LIQUID HEAT EXCHANGE MEDIUM, SAID STORAGE VESSEL BEING IN FLUID COMMUNICATION WITH SAID EVAPORATOR REGION; (C) AN EVAPORATOR HEAT EXCHANGER DISPOSED IN SAID EVAPORATOR REGION TO EFFECT HEAT EXCHANGE BETWEEN EVAPORATING REFRIGERANT AND HEAT EXCHANGE MEDIUM IN SAID REGION; (D) A LIQUID PUMP FOR CIRCULATING SAID HEAT EXCHANGE MEDIUM FROM SAID EVAPORTATOR REGION THROUGH A HEAT EXCHANGE LIQUID DISTRIBUTION CIRCUIT, AND RETURNIGN SAID HEAT EXCHANGE MEDIUM TO SAID EVAPORATOR REGION; (E) MEANS PROVIDING A LOW PRESSUR E THROAT REGION DISPOSED IN SAID HEAT EXCHANGE LIQUID DISTRIBUTION CIRCUIT; AND (F) VAPOR PASSAGE MEANS CONNECTING SAID LOW PRESSURE THROAT REGION WITH A VAPOR SPACE IN SAID STORAGE VESSEL FOR REDUCING THE PRESSURE IN SAID STORAGE VESSEL, THEREBY WITHDRAWING EXCESS HEAT EXCHANGE MEDIUM FROM SAID EVAPORATOR REGION INTO SAID STORAGE VESSEL WHEN SAID HEAT EXCHANGE MEDIUM IS CIRCULATED THROUGH SAID HEAT EXCHANGE LIQUID DISTRIBUTION CIRCUIT.
