Crystallization prevention control for absorption refrigeration machines
Abstract
Abstract A CONTROL WHICH SENSES IMPENDING CRYSTALLIZATION IS UTILIZED IN AN ABSORPTION REFIRGERATION MACHINE TO PREVENT SOLIDIFICATION OF ABSORPTIN SOLUTION IN THE CRITICAL AREAS OF THE MACHINE. A SENSING ELEMENT SENSES A RISE IN CONCENTRATED SOLUTION LEVEL BETWEEN THE GENERATOR AND THE HEAT EXCHANGER, WHICH RISE IN SOLUTION LEVEL IS INDICATIVE OF IMPENDING CRYSTALLIZATION. THIS SENSOR CAN ACTUATE ONE OR MORE OF A PLURALITY OF CONTROLS WHICH WILL CAUSE DILUTION OF THE CONCENTRATED SOLUTION IN THE HEAT EXCHANGER OR OTHER CRYSTALLIZATION PRONE AREAS. AS THE SOLUTION LEVEL IN THE CONDUIT BETWEEN THE GENERTOR AND THE HEAT EXCHANGER RETURNS TO AN OPERATING LEVEL, ADDITIONAL AUTOMATIC CONTROLS ARE ACTURATED TO PROCEED WITH A DILUTION AND SHUTDOWN CYCLE.
