Refrigeration components for basic experiments
|Name:||Refrigeration components for basic experiments|
ET 910.10 enables in conjunction with ET 910, ET 910.05 and the accessory set ET 910.12 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 of ET 910.05.
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.
