Air cycle air conditioning system and method
Abstract
Abstract APPARATUS AND METHOD UTILIZING COMPRESSOR BLEED AIR AND THE LIKE FOR ENVIRONMENTAL AIR CONDITIONING AND AS CONDITIONED SERVO FLUID. AN AIR CYCLE MACHINE EFFECTS COOLING AND DEPRESSURIZING OF A PORTION OF BLEED AIR, DIRECTING IT TO A PLACE OF USE FOR EVIRONMENTAL COOLING. ANOTHER PORTION OF THE BLEED AIR IS DIRECTED TO A PLACE OF USE AS A PRESSURE FLUID, IN BY-PASSING RELATION TO THE AIR CYCLE MACHINE. IN A REHEAT HEAT EXCHANGER THE TWO PORTIONS ARE BROUGHT INTO HEAT TRANSFER RELATION, WITH CONSEQUENT IMPROVEMENT IN THE RELATIVE HUMIDITY CHARACTERISTICS OF THE FIRST PORTION AND COOLING OF THE SECOND PORTION. PRESSURE REDUCING MEANS PROVIDES FOR EXPANSION OF THE SAID SECOND PORTION AND CORRESPONDING IMPROVEMENT IN RELATIVE HUMIDITY.
