Product Description

REFRIGERATOR MODEL

HSI training system for refrigeration and air conditioning technology. In combination with the base unit the operational model of a domestic refrigerator is created. The model is plugged onto the base unit, secured using fasteners and connected with refrigerant hoses to become a complete refrigeration circuit. consists of a refrigeration chamber with a heater as cooling load, evaporator, fan and various expansion elements. The fan supports the achievement of an even temperature distribution in the chamber. A cooling load can additionally be simulated with the heater. Solenoid valves enable the operation of the system with capillary tube or with expansion valve. All components are clearly arranged on a panel.

The operation of individual system components, here the temperature control, fan, heater, compressor and solenoid valves, takes place via the software. The software offers the option to simulate faults.

Temperatures and pressures in the system are recorded by sensors and displayed dynamically in the software. The effect of parameter changes can be tracked online in the log p-h diagram.

Fundamentals and individual components are represented in the educational software for. Performance assessments check the learning progress. With the aid of the authoring system further exercises and performance assessments can be created.

The unit shall perform the following experiments and investigations:
