Introduction to the composition of refrigerated truck refrigeration system and the role of each component（3）The evaporator is also a heat exchange device. The low-temperature and low-pressure refrigerant liquid after throttling evaporates in it to become vapor, absorbs the heat of the material to be

Introduction to the composition of refrigerated truck refrigeration system and the role of each component（2）The refrigeration system is composed of refrigerant and four major parts, namely compressor, condenser, expansion valve and evaporator. Compressor Compressor is the driving force of the refrig

Introduction to the composition of refrigerated truck refrigeration system and the role of each component（1）The principle of refrigeration of general refrigerators The compressor's role is to compress the lower pressure steam into higher pressure steam, so that the volume of the steam is reduced and

Analysis and prevention of hidden dangers of refrigerated truck accidents（2）During the unloading process, the cargo compartment was opened for too long.
