Analysis of R134a–DMAC vapour absorption refrigeration system with add-on components

Design, Fabrication and Analysis of Solar Vapour Absorption Refrigeration System

Solar energy is the most abundant source of energy available in our country. The power of the sun can be efficiently used to harness energy for solving our energy needs. The void of not having efficient technology to tap this abundant energy reservoir has led to search for better technologies and more varied applications. Our primary focus in this paper would be on utilizing solar energy for do...

Thermodynamic analysis of vapour compression refrigeration system using alternative refrigerants

This research is aimed to define , (1) the effects of refrigerant to the environment, (2) derive the eco friendly refrigerants by using software REFPROP, (3) describe the properties of refrigerant by mixing them in appropriate percentage, (4) reducing GWP and ODP by providing suitable substitute of CFC’s and HCFC’s refrigerants, (5) reducing the effect of refrigerant to the ODP. This analysis i...

Mathematical Model of a Vapour Absorption Refrigeration Unit

By means of carefully devised assumptions, a simple linear model is presented for an absorption refrigeration unit employing either water-lithium bromide or ammonia-water refrigerant-absorbent pairs. Absorption systems are an alternative to vapour compression systems by being thermally activated. Such heat energy may come from the sun or even from hot exhaust gases from a particular engineering...

Numerical Studies On Vertical Tubular Generator In Vapour Absorption Refrigeration System

Thermodynamic Analysis of Absorption Refrigeration System (ars) Ong Boon Hau

Absorption refrigeration system (ARS) continuously shows a growing interest in many applications due to cheap energy consumption and environmental friendly system. Typically, ARS system uses ammonia-water mixture where ammonia as refrigerant and water as absorbent. The system also consist hydrogen as auxiliary inert gas. While in this research, it is operated by using liquefied petroleum gas (L...
