CRD 400

HEAT PUMP WATER-WATER

Teaching suggested applications*

-          Identification of the components of a water/water heat pump installation

-          Visualization of the implementation of the system

-          Visualization of the transformation of the refrigerant through glass grilles (evaporation and condensation)

-          Power on, use and settings

-          Measurement of various operating parameters (electric consumption, temperature of  refrigerants and of water, pressures)

-          Energy efficiency analysis of the system and drawing of the refrigerating cycle enthalpy diagram

Description

The CRD400 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 into high pressure liquid. The 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 towards the pressure reducers. This one 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 on the water coil (and thus cooling it). The students visualize the transformation because the refrigerant evaporates between the glass grille and the cooling coil. At the outlet of the evaporator, the fluid is in the form of low pressure steam, it goes through a suction line accumulator and will be compressed once again by the compressor.

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

Its anodized aluminum structure on wheels makes it extremely robust as well as a great flexibility of integration into your premises. The manufacturing of this equipment meets the European machine directive
