....
The demonstrates the types of systems that are used in a lot of small applications in dangerous environments where systems using electrical power cannot be used or where there is no electrical power supply.
A Compressed Air Refrigeration Training Bench for studying refrigeration using compressed air. Using the whirling motion of a specially designed and shaped vortex distributor, the compressed air expands and is divided into a cold stream and a hot stream. This is an unusual method of producing cold air by the expansion of compressed air. The cold stream is utilised and the hot stream is exhausted into the environment.
The designed and manufactured to incorporate all current safety standards.
Experiments:
Thermodynamics of compressed air
Plotting the air transformation due to air expansion on a temperature-entropy diagram
Coefficient of performance (C.O.P) determination
Demonstration of producing hot and cold air through a system that has no moving parts
Determining the outlet temperature in relation to the feed pressure
Determining the useful refrigeration power
Detecting the operating curve of a vortex tube by varying the inlet pressure and the weight ratio between hot and cold air.

The Trainer On Domestic Refrigerators With Two Evaporators And Hermetic Compressor allows to study the circuit layout adopted in the normal domestic refrigerators with freezing room, fitted with positive temperature evaporator, negative temperature evaporator and hermetic compressor. A wheeled frame carries a horizontal working panel, fitted with a 80 mm clamp, and a vertical frame, where the main components of the unit and a screen printed synoptic panel are mounted at sight. The refrigerant is (HFC), CFC free, and the unit includes the measuring instruments that are necessary to monitor operating parameters and to test the refrigerator circuit. The student can rise his knowledge about the main components of a refrigerator plant, experiment the problems due to the filling and the emptying of the circuit and, at last, simulate some simple faults. The refrigerator circuit is made of copper pipes. The set of equipment and the vacuum and recharge station allow a fast assembly and disassembly of the refrigerator circuit.

Filling of a refrigerator circuit and leak detection.
Study of the main components.
Fault simulation.
