    2. Structural Features and Working Principle 2.1 Main Functions SIC-W air-cooled water chillers include consists of four main components, which are compressor, condenser, thermostatic expansion valve, and evaporator. The system adopts single-stage vapour compressed refrigeration system, which uses refrigerant gas-liquid conversion to absorb and release heat, thus achieving the cooling effect.
  • Page 16 refrigerant from the condenser through the drying filter 4 that flows to the liquid pipe solenoid valve 5 and refrigerant indicator 6 after drying and impurity filtering, and finally reaches the expansion valve 7. In the F-G process, the temperature of high pressure liquid refrigerant decreases after thermal expansion valve throttling and depressurizing.
