CRD 500


Teaching suggested applications*

-          Identify the components of a refrigeration installation with exchanger water/ water or air / water

-          Commissioning and setting a heat pump installation

-          Establish an energy balance on the various elements of the thermodynamic cycle (compressor, condenser, expansion valve and evaporator)

-          Record the experimental points (temperature and pressure) of the thermodynamic cycle

-          Determine the C.O.P. for different water flow rates


The CRD500 bench allows the study of refrigerating cycle.

The bench is made of standard elements of a refrigerating circuit. The compressor will first elevate the pressure and the gas temperature (R134a). The water condenser will then transform this high pressure gas in the high pressure liquid. Students visualize the transformation because the refrigerant condenses between the glass grille and the cooling coil.

The high-pressure liquid will then be stored in a bottle and then be sent to the expansion valve. This will change the state of the fluid, it will go from a high pressure liquid to a low pressure liquid. This low pressure liquid is now in the evaporator and will draw its energy to the water coil (and thus cooling it) or on the air following the selected evaporator. Students visualize the transformation (for water evaporator) because the refrigerant evaporates between the glass grille and the cooling coil. At the outlet of the evaporator, the fluid is in the form low pressure steam, it goes through a suction line accumulator and be compressed again by the compressor.

The robust design of this equipment makes it perfectly suited for use in schools.

Its anodized aluminum structure on feet gives it great robustness as well as great flexibility of integration into your premises. The manufacturing of this equipment meets the European machine directive
