    2. Structural Features and Working Principle 2.1 Main Functions SIC-A-EB Budget Air-cooled Water Chiller is constituted by 4 parts: compressor, condenser, capillaries and tube evaporator. It adopts the single-stage vapour compression refrigeration system and obtains the rifregirating effect by refrigerant gas-liquid transformation and heat absorption and release principle.

  • Page 14: Main Parts And Functions

    1) Compressing and conveying the refrigeration steam and forming low pressure in evaporator and high pressure in condenser, the compressor is the core of the whole system. 2) SIC-A-EB adopts scroll compressor. Picture 2-2: Compressor 2.1.2.2 Condensor 1) Condenser is a heat output device which is used to discharge the heat absorbed by the evaporator and converted by the compressor to the cooling medium.
  • Page 15 2) The size of the filter is usually chosen according to the caliber of the cooling agent pipe. Picture 2-4: Drying Filter 2.1.2.4 Capilliary or Thermal Expansion Value 1) The capilliary or the thermal expansion valve throttles the refrigerant and reduces the pressure of it, as well as regulate the refrigerant flow which enters the evaporator.
  • Page 16 Picture 2-6: Evaporator 2.1.2.6 High and Low Pressure Controller 1) The high and low pressure controller is used to check the working pressure of the compressor's inlet and outlet. 2) The high-pressure controller is set to 37bar, and the low-pressure controller is set to 4bar.
