Study of Ammonia Water Vapour Absorption Refrigeration Chiller Run by Solar Thermal Energy

Now, most of the energies are used by the industries due to depletion of fossil fuels and continuous increases in the cost price and demand for energy has led to more research and development to utilize available energy resources efficiently by minimizing waste energy. For this Absorption refrigeration systems increasingly attract research interests because Absorption cooling offers the possibility of using heat to provide cooling. For this purpose solar heat can be used. Absorption system is divided into two categories depending upon the working. These two categories are the Libr-H2O and NH3-H2O.In LiBr-H2O system water is used as a refrigerant and Libr is used as an absorbent, while in NH3-H2O system ammonia used as an refrigerant and water is used as an absorbent, which used as in studying and developing a new absorbent refrigerant system. The objective of this review paper is to gives the fundamental knowledge and performance of Ammonia water (NH3-H2O) vapour absorption system run by solar energy. This system is eco friendly in nature.
