Economic Viability of Solar Absorption Cooling System in Pakistan

In developing countries, electricity demand is ever increasing. The growing trend in the number of skyscraper building structures and increase in the use of electrical equipment installed in industrial as well as commercial buildings. Shortfall of electricity in Pakistan and a large difference in demand-supply of electricity emphasis on the alternative / cost effective solutions of the electricity and as well as cooling. In this regard, the uses of cooling technologies like Absorption Cooling have been a desired solution due to instantaneous availability of the sun in the region. The ever increasing / expanding infrastructure always required to complete energy demands, along with the necessity of cost reduction and higher reliability requirements, which drives towards the alternative resources to include cost reduction, reliability, available resources and efficiency. This increasing load / demand especially in expansion of projects required increased electricity consumption and resultantly cooling demand. Depending on the region, more than half the energy consumed can be for powering air conditioning and refrigeration equipment. And electrical power costs for cooling are often the largest expenditure for most occupied buildings. Absorption Cooling System (ACS) is an alternative substitute for Conventional Compression Cooling (CCC) when electrical power is unreliable and costly.
