  • Page 19: Structural Features And Working Principle

    2. Structural Features and Working Principle 2.1 Main Functions SIC-R2 water chiller is mainly made up of four components. They are compressor, condenser, thermostate expansion valve and evaporator. The machine uses single stage vapor compression refrigeration system and takes the advantage of the mechanism of transformation between gas and liquid for absorbing and releasing heat by using of refrigerant to achieve the effectiveness of refrigeration.
  • Page 20 Hot-air bypass function: the compressor continues working when process water is cooled down to required temperature, then the hot-air bypass valve opens as the temperature drops to its set value. A part of the refrigerant from the compressor passes through the by-pass valve and then reaches evaporator, balancing out part of the machine refrigerating capacity and then goes back to compressor without passing through the condenser.
  • Page 21 opens as the temperature drops to its set value. A part of the refrigerant from compressor passes through by-pass valve and then reaches evaporator, balancing out part of the machine refrigerating capacity and then goes back to compressor without passing through condenser. With the help of hot-air bypass valve, system can stay in balanced condition and meanwhile can keep control accuracy within ±1 .
