Abstract

The invention belongs to the technical field of laboratory climate environment adaptability analysis and testing, and particularly relates to a liquid nitrogen evaporation refrigeration large-flow all fresh air compensation system. The system comprises a box body, a liquid nitrogen evaporation refrigeration module and a control module. A compensation air duct is arranged in the box body. The liquid nitrogen evaporation refrigeration module comprises a liquid nitrogen heat exchanger, a water defrosting device and a liquid nitrogen discharging device, wherein the water defrosting device and the liquid nitrogen discharging device are matched with the liquid nitrogen heat exchanger. The compensation air duct is sequentially provided with a filter screen, a compensation fan, the liquid nitrogen heat exchanger and an air valve from an air inlet to an air outlet. The control module is used for controlling the liquid nitrogen evaporation refrigeration module, the compensation fan and the air valve. The liquid nitrogen evaporation refrigeration large-flow all fresh air compensation system can be applied to a civil aircraft engine starting test under the extremely low temperature in a large comprehensive climate laboratory; and the system also has the advantages of high reliability and safety, good controllability, flexible configuration and the like.

Description

technical field [0001] The application belongs to the technical field of laboratory climate environment adaptability analysis and testing, and in particular relates to a liquid nitrogen evaporative refrigeration large-flow all-new air compensation system. Background technique [0002] The large-scale comprehensive climate laboratory can simulate the climate environment of the earth's surface such as extreme low temperature, high temperature, heat and humidity, snowfall, solar radiation, freezing rain, rain, freezing fog, etc., and its size can meet the climate test requirements of large-scale equipment or complete machines. Among all the test items for the aircraft, the start-up and working test of the engine under extreme weather conditions is one of the most important assessment items. To carry out the aircraft engine starting test under extremely low temperature in the closed space of the aircraft climate environment laboratory, it is necessary to discharge the high-tempe...
