40 years of reform, the past and present of China Railway Signal

Refrigeration compressor is the core and heart of refrigeration system. The capacity and characteristics of the compressor determine the capacity and characteristics of the refrigeration system...

Amendment and Implementation

1. The air compressor compressed air intake temperature is too high or the flow rate is too large. 2. The working conditions of the refrigeration system change, causing the refrigerant evaporation temperature to rise, so that the compressed air can not be cooled enough in the evaporator...

The lack of core technology inhibits the development of refrigeration compressors

Sometimes, the quality of compressed air cannot be solved by connecting a device to a compressed air supply station. In order to obtain the appropriate mechanical efficiency and product quality...
