Product Description

Advanced TechnocracyInc. is Manufacturer, Exporter & Supplier of Vapour Absorption Refrigeration Test Rig.

This type of refrigerator was known as three fluid refrigerationsystem. The elimination of aqua pump from the absorption system with thecomplete absence of moving parts and work input. The main purpose of removingthe pump was to make the machine noiseless. It uses refrigerant as a solvent sand an inlet gas for inlet of the system. The inert gas is continued to thelower side of system only by its system. It is possible to maintain the uniformpressure throughout the system and after sometime permitting the refrigerant toevaporator at low temperature corresponding to its partial pressure. In thehigh pressure side system (generator and condenser), there exists only therefrigerant which is subjected to total pressure of the system so that it iscondensed by using normal cooling water as air as it is done in other system. Thestrong aqua ammonia solution is heated in generator by the application ofexternal heat source. The water vapor carried with ammonia vapor is removed inseparate form as shown in figure. Then the dry ammonia vapor is passed into thecondenser and it is condensed by using external cooling source. The liquidammonia flows under gravity in the evaporator and it evaporates. The mixture ofhydrogen and ammonia vapor is passed into the absorber and the weak solutionfrom aqua ammonia from the separator is allowed to follow into the absorber,through tray this weak aqua ammonia solution comes into contact with hydrogenseparated. This strong solution is further passed to the generator and itcompletes the cycle.


  • Switch on the main supply.
  • Start the bulb inside the cabin.
  • Adjust current and the supply voltage.
  • Take the initial temperature reading.
  • Repeat the procedure after sometime.
  • Take readings until the steady state is reached.
  • When steady state is reached, take this reading for calculationand find the COP.
