Claim 1
Independent Claim
126 words
A METHOD FOR CONTROLLING THE TEMPERATURE OF A FLUID REMOVED FROM A SOURCE THEREOF COMPRISING RREMOVING SAID FLUID FROM SAID SOURCE BY AND THROUGH A PUMPING ZONE, PASSING SAID FLUID FROM SAID PUMPING ZONE THROUGH A HEAT EXCHANGE ZONE, SENSING THE TEMPERATUER OF SAID FLUID AFTER PASSING SAME THROUGH SAID HEAT EXCHANGE ZONE, AT LEAST REDUCING THE RATE OF REMOVAL OF SAID FLUID FROM SAID SOURCE IN RESPONSE TO A SENSED TEMPERATURE BELOW A PREDETERMINED MINIMUM VALUE, SENSING THE RATE OF FLOW OF SAID FLUID FROM SAID SOURCE AT LEAST ONE OF UPSTREAM AND DOWNSTREAM POINTS OF SAID PUMPING ZONE, AND AT LEAST REDUCING THE RATE OF REMOVAL OF SAID FLUID FROM SAID SOURCE IN RESPONSE TO A SENSED FLOW RATE BELOW A PREDETERMINED MINIMUM VALUE.
