Refrigerator model is a part of the refrigeration and air-conditioning training system. In combination with the base unit, the operational model of a domestic refrigerator is created. The model is plugged onto the base unit, secured using fasteners and connected with refrigerant hoses to become a complete refrigeration circuit.

                                     
  • The model of a refrigerator is designed to be plugged into the base unit to simulate a real refrigerator.
  • The refrigerator model is composed of inlet and outlet valves, solenoid valves, expansion valves, capillary tube and refrigeration chamber.
  • The refrigeration chamber is provided with evaporator, fan and cooling load.
  • The chamber is provided with transparent front.
  • The expansion elements are selected via solenoid valves to be either expansion valve or capillary tube.
  • The sensors are used to record temperature and pressure at different measuring points, the measured values of the sensors can be observed through the software.
  • The software operates the solenoid valves, fan, heater and fault simulation.
  • The software with control functions and data acquisition are via USB.
  • The software acts as an educational software, data acquisition, system operation.
  • A non-linear electric heater is used to generate the heating load.
