ENERGY EFFICIENCY EVALUATION OF TOTALIZED HYDROGEN ENERGY UTILIZATION SYSTEM FOR COMMERCIAL BUILDINGS

摘要

Results from evaluating total building energy efficiency allowed reaching the following conclusions. 1) The higher the building heat-electricity rate and the higher the waste heat utilization efficiency, the more superior THEUS is to the other systems. The hydrogen system is suitable to commercial buildings that are required much heat demand. 2) Compared with ice storage, THEUS attains at least a 27% energy saving for whole building.
