With this training system practical experiments relating to the operation of a refrigeration system can be implemented by
dealing with differently configured compression refrigeration circuits. The components used are common in refrigeration and
therefore closely related to practice.
The base unit includes the main components of a refrigeration circuit: a condensing unit with compressor, condenser and
receiver and a refrigeration chamber with integrated evaporator, fan for forced ventilation and an electric defrost heater. A
pressure switch protects the compressor against excessive pressure. The refrigerant flow can be modified via shut-off valves.
Together with the components from. heat exchanger, flow meter or manometer, simple refrigeration circuits are realised. For
continued experiments additional refrigeration components from are used, e.g. post-injection valve, capacity controller or defrost timer. All components of the training system have ball valves at the connections. Using the required accessory kit the
components are connected into a complete refrigeration system. For the complete experimental setup, laboratory workplace with frame for mounting the components and power supply, is required. The CFC-free refrigerant R134a serves as working medium.
With the service set additional exercises for the filling and evacuation of refrigeration systems are carried out.
The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
The unit shall perform the following experiments and investigations:
