The invention is suitable for the technical field of wind tunnel experiments, and provides an icing wind tunnel heat exchanger outlet airflow temperature control system and method, and the system comprises a compressor, a condenser, a liquid storage tank, a refrigerant shield pump, a heat exchanger, a low-pressure circulation barrel, a controller, and an upper computer. An air suction pressure sensor is arranged at the air suction end of the compressor; an inlet and an outlet of the heat exchanger are respectively provided with a liquid inlet regulating valve and an air return regulating valve; a downstream air outlet of the heat exchanger is provided with a temperature sensor, and the temperature sensor and the heat exchanger are both arranged in the icing wind tunnel; the controller is in control connection with the compressor; the upper computer is connected with the temperature sensor, the return air regulating valve and the controller; the air suction pressure sensor is directly arranged at the air suction end of the compressor, the air suction pressure of the compressor can be visually and sensitively obtained, and the problems that in the prior art, due to the large volume of a low-pressure circulation barrel, the load increasing and decreasing speed of a refrigerating system unit is low, and finally the heat exchanger outlet airflow temperature has large hysteresis quality are solved.

    本发明适用于风洞实验技术领域,提供了一种结冰风洞换热器出口气流温度控制系统及方法,包括:压缩机、冷凝器、储液罐、制冷剂屏蔽泵、换热器、低压循环桶、控制器和上位机;压缩机的吸气端设置有吸气压力传感器;换热器的入口和出口分别设置进液调节阀和回气调节阀;换热器的下游出风口设置有温度传感器,且温度传感器与换热器均设置于结冰风洞中;控制器控制连接压缩机;上位机连接温度传感器、回气调节阀和控制器;将吸气压力传感器直接设置在压缩机的吸气端,可以直观并且灵敏的获得压缩机的吸气压力,解决了现有技术中因低压循环桶容积大,导致制冷系统机组增减载速度慢,最终导致换热器出口气流温度存在较大的滞后性。
