    2. Structural Features and Working Principle 2.1 Main Functions SIC-A-R2 series are applicable for cooling molds to reduce products molding cycle, also they are available in the cooling of equipments in order to maintain a normal temperature. Besides, they are suitable for other industries with the need of cooling.
  • Page 18 Hot-air bypass function: the compressor continues working when the process water is cooled down to the 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 bypass valve and then reach the evaporator, balancing out part of the machine refrigerating capacity and then goes back to the compressor without passing through the condenser.
