About Refrigeration System With Open Compressor

REFRIGERATION SYSTEM WITH OPEN COMPRESSOR

Basic experiments in the field of refrigeration. The trainer includes a closed refrigeration circuit with open compressor, a condenser with fan, a thermostatic expansion valve and an evaporator in a refrigeration chamber with transparent door. A fan in the refrigeration chamber ensures an even temperature distribution. A cooling load is simulated by an adjustable heater in the refrigeration chamber. The drive unit drives the compressor via a V-belt. The compressor speed is set at the . The circuit is equipped with a combined pressure switch for the delivery and intake side of the compressor.

All relevant measured values are recorded by sensors. Digital displays indicate the measured values. The simultaneous transmission of the measured values to a data recording software enables convenient analysis and the representation of the process in the log p-h diagram. The software also displays the important characteristics variables of the process, such as the refrigeration capacity and the coefficient of performance.

The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.The unit perform the following experiments and investigations:
