It enables in conjunction with it and the accessory set the
design and performance of various basic experiments related to refrigeration.
Commercial components are used in practical experiments. These components are
mounted on plates ready to be connected and are arranged clearly in the frame.
The set includes simple refrigeration components, such as expansion elements
and filters, as well as electrical components, e.g. switches and thermostat.
The superheater included in the set is a heat exchanger ensuring the complete
evaporation of the refrigerant before entering the compressor whilst the liquid
refrigerant is supercooled upstream of the expansion element. The control
behaviour of the expansion element is monitored at the flow meter. Manometers
provide an insight to the pressure ratios in the refrigeration circuit. Via
pressure and temperature measurements the change of state of the refrigerant
can be tracked and entered into the log p-h diagram. The temperature is
measured by interlaboratory thermometers.
