AbstractDevelopment of simulation model and parametric study of simple cooling, absorption, vapor compression, and steam ejector compression cycles are presented. Based on the simulation model, technical and economic analyses of various sources of energy driven cooling systems are evaluated. In the technical analysis, different cooling systems are compared by system performance measures such as COP, and exergetic efficiency, and primary energy ratio. System performance measures of electricity driven vapor compression system is better than others. In economic analysis, unit operating cost comparison ls done for selected Asian countries, namely Indonesia, Malaysia, Myanmar, Palcistan, and Thailand, based on the different energy prices of respective countries. Evaluation of most cost effective cooling system is done for these countries. Depending on the price structure of each country, unit operating cost for each system is different. Natural gas driven system is cost effective in Indonesia. In Pakistan, Malaysia and Thailand, fuel oil driven reciprocating engine system ls favorable. Because of lower electricity price in Myanmar, electricity driven vapor compression system is economical. The comparison does not include initial setup cost and maintenance cost. The economic analysis of the absorption cooling system operating with hot water is not included because the hot water is expected to be the industrial waste heat without any economic value. Industrial process cooling system consumes large percentage of energy used in industry. It is important to improve energy use in the system itself through wast e ut111zation. Improvement has been made by utilizing waste heat in the form of hot water or low pressure steam ejected from industrial processes to drive absorption cooling system as shown in a fruit canning industry. Cooling water and electricity requirements will be r educed by this improvement. In addition there is no significant energy input required to drive the absorption system used.
