ALLGEMEINE BESCHREIBUNG

The Introduction to Refrigeration Unit, "TIR", is a system with exchangeable modules in which the components are mounted on plates and are rapidly connected by flexible hoses.

The unit consists of a frame where 6 of the 8 modules are positioned at the same time, connecting them by cables and flexible hoses, allowing for the construction of simple compression refrigeration systems.

The modules are formed by the components mounted on plates and are ready to be easily mounted on the frame.

The experimental unit includes all the components required for a fully operational refrigeration circuit, such as compressor, condenser, evaporator and a capillary tube as expansion element. Other additional accessories in refrigeration systems are also included: pressure switch and manometers to protect the compressor against excessive pressure, flow meter and sight glass with filter/drier and display and control panel.

The unit allows for different combinations of the components, since there are two condensers and two evaporators, one as air-refrigerant heat exchanger and the other water-refrigerant heat exchanger.

To fill and drain the system the "T/KIT3", Refrigerant Filling and Evacuation Module, is recommended.

With this unit the student can perform easy experiments that demonstrate the processes in the equipment and the changes in the refrigerant state. Advanced experiments allow the use of the equipment as a refrigeration system and as a heat pump, depending on the configuration of the components.

Pressures, flow rates and power consumption of the compressors are displayed as the most important characteristic variables of refrigeration circuits.

The temperature is measured by thermometers belonging to the laboratory.
