Deicer, air circulation machine and air circulation refrigeration system

Abstract

The invention provides a deicer, an air cycle machine and an air cycle refrigerating system, the deicer is mounted on a connecting pipe, and the deicer comprises a deicing piece; the deicing piece is provided with a connecting end and a working end, the connecting end extends out of the connecting pipe, the working end extends into the connecting pipe, and the deicing piece is movably arranged in the radial direction of the connecting pipe; the connecting pipe comprises an air inlet end and an air outlet end, and when the pressure difference between the air inlet end and the air outlet end in the pipe exceeds a set value, the deicing piece moves in the radial direction of the connecting pipe so that the working end can remove accumulated ice. According to the principle that accumulated ice can influence air flowing pressure, whether the accumulated ice needs to be removed or not is judged according to the pressure difference in the air inlet end and the air outlet end, the deicing piece can move according to the result of the pressure difference, and pressure coordination between the deicer and the pipeline is achieved.
