Performance Enhancement of Simple Vapour Absorption System Using Loop Heat Pipes

Abstract

A Vapour Absorption Refrigeration System is able to use waste heat, which makes it very useful in the Energy Crisis. In this research work, as beginning a loop heat pipe (LHP) with different specifications are employed to re-use the heat that has been rejected in the widely used conventional condensers. The condensation after the generator occurs in as a flow condensation as it rejects heat to the evaporator of LHP. Hence by removing the conventional condenser or by reducing its size, it will drastically result in cost reductions. This research work finds that COP I increases by up to 80% due to the re-use of heat. Also due to the removal of the bulky anergy creating parts, the exergy losses are reduced and the COP II increases up to 30%. The size of the system reduces and the system becomes easy to operate.

Investigation on the Performance of Domestic Refrigerator with Zirconium Oxide‐R134a Nanorefrigerant

“…Imaduddin [29] used the refrigerant R134a and POE oil (300 ml) suspended with TiO 2 nanoparticles (2.5 g). The author found that the COP increased by 22.5 percent when compared to R134a VCRS without nanoparticle.…”
