ABSTRACT
In this paper a comparative study between the solar powered standards Single-Effect (SE) and Single-Effect Double –lift (SE/DL) absorption machines with identical cold output, using the same collector model is given with a special focus in solar unit part. Performance and economic analysis of the solar energy unit part of the two different cycles have been carried out for a wide range of operating conditions.Various collector types from Asian and European markets have been used as the source of energy providing hot water driving the absorption machines. The solar SE/DE allow to collecting more energy, thus saving more nonrenewable energy source,due to the mean increase in collector efficiency from 2% to 20% depending on the chosen collector .In 20 years lifetime economical analysis,the cost of this saved energy correlated to an equivalent electrical energy is more than balanced the expense at the corresp[onding increases in the installed collector surface area. Consequently implying a profitability by unit cooling capacity of about 2200$ for the conventional single glazed flat plate collector and about 800$for the spcial designed low cost single glazed flat plate collector, at hot water supply/return temperatures 90/65°C.the vacume tube collector becomes profitable when the driving hot water temperature is greater than 92°C.
