Open type air refrigeration cycle device passively absorbing refrigeration capacity

Abstract

The invention belongs to the airplane environment control technology, and particularly relates to an open type air refrigeration cycle device passively absorbing refrigeration capacity. The open type air refrigeration cycle device passively absorbing refrigeration capacity comprises an air turbine refrigeration channel and a passive absorption refrigeration capacity channel, wherein the air turbine refrigeration channel and the passive absorption refrigeration capacity channel are connected with engine entrainment air, the passive absorption refrigeration capacity channel comprises a primary radiator, a secondary radiator and a refrigeration capacity valve, outlet air of a condenser is communicated with a cold air duct through the refrigeration capacity valve, cold sides of the primary radiator and the secondary radiator are located in the cold air duct, and hot sides of the primary radiator and the secondary radiator are located in the air turbine refrigeration channel. According to the open type air refrigeration cycle device, the passive absorption refrigeration capacity assembly is arranged, the engine high pressure entrainment air is used for circulation cooling of a cockpit, a specialized ram-air air inlet area is reduced, airplane performance compensatory loss can be substantially reduced, hiding demands of high-performance combat aircrafts are met, and the open type air refrigeration cycle device has the advantages of being large in refrigerating capacity, small in size and high in reliability.

Description

technical field [0001] The invention belongs to aircraft environment control technology, and in particular relates to an open air refrigeration cycle device for passively absorbing cold energy. Background technique [0002] The main advantages of the air cycle refrigeration technology are: the quality of the equipment is small; the cost is low; the adjustment and control are convenient; the workload of overhaul and maintenance is small; the arrangement of accessories on the aircraft has no special requirements; For pressurization purposes, cabin ventilation, pressurization and cooling can be done by the same system. [0003] The traditional air cooling device uses ram air as the cold side of the system, which requires a large ram air inlet, and the ram air intake volume is large, which has the problem of large performance compensation loss and is not conducive to the stealth of the aircraft. Contents of the invention [0004] The purpose of the present invention is to pro...
