    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.
