Refrigeration Demonstration Manufacturer,Supplier and Exporter in India
Product Code : EL-TWL-13124
Jlab Export is a leading Refrigeration Demonstration Manufacturer,and suppliers in India
The Refrigeration Demonstration unit shows the basic refrigeration cycle with its four main parts: compressor, condenser, evaporator and control device. Laid out so the cycle can be followed by eye, they cool a small enclosed compartment under an electronic temperature control. Three explosion-proof sight glasses let the class watch the R-134a as it circulates. It arrives assembled, charged and ready to run.

Classroom Demonstrations of the Cycle
Teachers start the unit at the beginning of a lesson. They then trace the refrigerant path with the class, from the compressor to the condenser, through the control device and into the evaporator. Manifold Gauges For Refrigeration Systems show the high and low side pressures, and the R-134a scale on each gauge gives the matching boiling temperature.
Students can tape a Temperature Sensor to the pipes at the inlet and outlet of each part and plot how the compartment cools after start-up. A cut-away such as the Reciprocating Hermetic Compressor then shows what happens inside a sealed compressor.
Frequently Asked Questions
What does each of the four main parts do?
The compressor raises the pressure and temperature of the refrigerant vapour. The condenser gives that heat to the room, and the vapour turns to liquid. The control device drops the pressure, and in the evaporator the liquid boils and takes heat out of the compartment.
What can students see through the sight glasses?
The three sight glasses show the refrigerant moving round the circuit. A clear, full glass in a liquid line means liquid only, while a stream of bubbles where liquid is expected points to flash gas or a low charge.
Is the unit ready to use on delivery?
Yes. It comes completely assembled and charged with refrigerant. Place it on a level bench, connect a 220 V, 50 Hz supply and set the electronic temperature control for the compartment.
How does the electronic temperature control work?
It senses the compartment temperature, stops the compressor when the set point is reached and starts it again as the compartment warms. Logging the temperature shows this on and off cycling clearly.
How is it different from a refrigeration test rig?
This unit is built to show the cycle in a classroom. The Refrigeration Test Rig has an instrument panel for measured work on the vapour compression cycle and its coefficient of performance.
