ABSTRACT
In the first paper energy saving rate of the solar SE/DL vs. solar SE systems has been analyzed, and it was found that using a low cost special designed single glazed flat plate solar collector with selective surface as heat source it can be saved 822$/KW at heat source supply/return temperature 90/65°C in 20 years lifetime of the system. In the present paper we present the computer simulation results of a full comparative study between the two systems with identical cold output at 14/9°C using the above mentioned solar collector model as heat source. It is found that the SE/DL is profitable when the supply temperature is less than 100°C at return temperature 65°C.For Th =90°C the profitability will be 490$/KW at Tr =75 °C and drop to 298$/KW at Tr =60°C in 20 years system life. The profitability depends also on the system lifetime, the working-hours per year and the chiller unit cost per Ton.
