摘　　要：针对气候实验室飞机发动机低温起动试验时,室外超大流量高湿度空气经过低温换热器出现的换热器表面积大量结霜现象进行研究,提出了一种能够有效抑制换热器结霜的换热器组布置方案,从而保证发动机开车试验连续进行,不因换热器大量结冰引起的换热效率快速降低而导致试验中止。In the course of low temperature starting test of aircraft engine in climatic environment test facility,a large number of frosting phenomena of heat exchanger surface area caused by outdoor super large flow and high humidity air passing through low heat exchanger are studied.A scheme of heat exchanger group arrangement which can restrain ices are put forward to ensure the test run of engine start-up.And No test suspension due to the rapid reduction of heat transfer and electricity caused by heat exchanger crate.
