Résumé

Most advanced research has been carried out to increase the coefficient of performance of a Li Br/H20 Vapor Absorption System (VAS). VAS uses thermal energy to generate heat which is used in a generator to evaporate refrigerant out of the solution. The thermal energy produced by burning the fossil fuel causes a lot of CO2 emission to the environment. The OPEX to generate heat for VAS from fossil fuel is always high. The aim of this paper is to use the thermal energy from renewable solar energy, which has zero ozone layer depletion potential and zero global warming potential.
This paper will give a fair idea about the economic constraints and the payback calculation of a solar based VAS over a conventional fossil fuel based VAS. The present research work mainly consists of three parts. In the first part, calculation of heat load is carried out for a single-storey conference hall with 100 occupants. In the second part of the study, calculation of heat required at the generator in a VAS to maintain the desired temperature in the conference hall is calculated. In the third part of the study, selection of a solar collector to generate the thermal energy required at the generator is done and the solar collector area is calculated. The results and calculation derived from the study gives a fair idea about the viability of VAS system with solar energy over conventional system.
