I. THE BASIC COMPOSITION OF REFRIGERATED TRUCK REFRIGERATION UNIT
Refrigerated truck refrigeration system is mainly composed of the following key components:

1.1,Compressor: the heart of the system, responsible for compression and circulation of refrigerant
1.2. Condenser: high temperature and high pressure gaseous refrigerant cooled to liquid state
1.3. Expansion Valve: controls the flow of refrigerant and reduces the pressure
1.4. **Evaporator**: Absorbs heat from the compartment and cools it down.
1.5. Control system: monitoring and regulating temperature, humidity and other parameters
1.6. Fan system: promote air circulation, ensure uniform temperature
