Solar Powered Vapour Absorption Refrigeration (SPVAR) System as a Rural Microenterprise


The continuous increase in the cost and demand for energy has led to more research and development to utilize available and renewable energy resources efficiently. The absorption refrigeration system (ARS) is becoming more important because it can produce higher cooling capacity than vapor compression systems, and it can be powered by other sources of energy (like waste heat from gas and steam turbines, sun, geothermal, biomass) other than electricity. But as far as COP of these refrigeration systems is concerned, it is always a challenge to the researchers to significantly increase the COP for these systems. The most popular refrigeration and air conditioning systems at present are those based on the vapour absorption systems. These systems are popular because they are reliable, relatively inexpensive and their technology is well established. However, these systems require high grade energy for their operation. There are still problems to be solved in research field, especially small cooling capacity machine (about 1 to 10 kW) which are suitable for small farmers and residential uses. Apart from this, the recent discovery that the conventional working fluids of vapour absorption systems are causing the ozone layer depletion and greenhouse effects has forced the scientific researchers to look for alternative systems for cooling applications. The natural alternative is of course the absorption system, which mainly uses heat energy for its operation. Moreover, the working fluids of these systems are environment friendly. The present study elaborates feasibility of such systems using H2O'LiBr solution and exergy analysis.
