Mathematical model of a vapour absorption refrigeration unit

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...

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...

Mathematical Model of a Lithium-Bromide/Water Absorption Refrigeration System Equipped with an Adiabatic Absorber

The objective of this paper is to develop a mathematical model for thermodynamic analysis of an absorption refrigeration system equipped with an adiabatic absorber using a lithium-bromide/water (LiBr/water) pair as the working fluid. The working temperature of the generator, adiabatic absorber, condenser, evaporator, the cooling capacity of the system, and the ratio of the solution mass flow ra...

Transient Characteristics of a Single-Effect Absorption Refrigeration Cycle

This paper deals with a lumped-parameter dynamic simulation of a single-effect LiBr-H2O absorption chiller. In many studies the thermodynamic properties of LiBr-H2O solution were taken from some approximate relations causing the results to be somewhat inaccurate. These relations were used to solve simultaneous differential equations involving the continuity of species constituting the LiBr-H2O ...
