Abstract
This study has examined the economic feasibility of adsorption-based district heat driven cooling system compared with convention air compression unit through a techno-economic model built in GAMS. The article describes the model settings, equations and input data as well as the result and discussions. The sensitivity analysis of adsorption investment cost, heat price, electricity price and the discount rate and two other scenarios of other locations and of constant outdoor temperature profile are also included. Overall, the results indicate that this type of system is not competitive, mainly because of its technological constrains by temperature. Only when a fixed outdoor temperature profile is assumed plus free heat, adsorption systems would be preferable. This implies that the potential of its application at other climate and free heat source is still worth investigating.
