Abstract
As a novel solar cooling facility in the building with many floors, the solar absorption-subcooled compression hybrid cooling system (SASCHCS) is not evaluated economically and environmentally. Consequently, the paper mainly contributes to the above-mentioned study to show the potential of the SASCHCS. The evaluation, performing by the dynamic simulation based on the monthly typical cooling demand and meteorological data, is by the comparison of SASCHCS and the solar PV cooling which is thought to be the most economical solution recently. It is found that the SASCHCS is economically better than the solar PV cooling though the saving of CO2 emission in the SASCHCS is less. Besides, the SASCHCS becomes more economical and attractive as the performance of its compression subsystem is poor. The payback period of the SASCHCS drops to 17.6 yr when the performance of compression subsystem comes down by 20%. The paper is helpful to promote the application of the SASCHCS.
