Computerized Vapour Absorption Refrigeration Test Rig

Description

This test rig is used to great advantage when introducing students to the Vapour absorption refrigeration cycle. The Vapour absorption refrigeration system is an Electrolux make, it resembles to a mini household refrigerator. The Vapour absorption system used in the rig consists of generator, condenser, evaporator, absorber and a heater, which is all in a sealed unit therefore; the pressure and the flow rate of ammonia inside the circuit cannot be measured.

The test rig is portable trolley mounted, housed on a MS frame tube with wooden platform & front panel, finished by lamination to give elegant finish. The panel consists of all the necessary instruments like voltmeter, ammeter, and temperature inductor.

Required temperature at generator, condenser, evaporator, absorber & heater are measured. The power consumed by the unit is measured using a digital voltmeter & ammeter.
