This training system represents a typical refrigeration system composed of compression, evaporation, expansion, and condensation. Within this training system, trainees will get to see clearly the state of used refrigerant whether it’s in the liquid or the vapor phase or transitioning between these two phases. The system is reliable allowing trainees to get familiar with refrigeration cycle basic components and stages.

                                     
  • The training unit represents a typical refrigeration circuit consisting of a hermetic piston compressor, condenser, expansion valve and evaporator.
  • The evaporator and condenser are transparent to provide good monitoring of the phase transition process during evaporation and condensation.
  • Before the entry into the evaporator the aggregate state of the refrigerant can be monitored at a sight glass.
  • A water circuit cools the condenser or supplies the cooling load for the evaporator.
  • Flow of water and refrigerant is adjustable.
  • The low-pressure level of the refrigerant used permits the use of an evaporator and condenser out of glass.
  • The key points of the cyclic process can be read.
  • The power of the compressor and flow rates of the water flows and the refrigerant are also indicated.
  • The measured values are demonstrated on digital displays.
  • The flow rate of the refrigerant is determined by a flow rate sensor
  • The unit is equipped with ON/OFF & Emergency switches.
