Feature
Practice-oriented basic experiments using real components from within the industry

Tesca Basic Refrigeration Components 32422 enables in conjunction 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 super-heater included in the set is a heat exchanger ensuring the complete evaporation of the refrigerant before entering the compressor whilst the liquid refrigerant is super-cooled upstream of the expansion element. The control behavior 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 inter-laboratory thermometers.
The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
