Hybrid Air-conditioning System Efficiency for Districts in the Tropics

摘要：

　　Hybrid air-conditioning systems in buildings have a high potential to utilize resources in an efficient and sustainable manner in districts. The goal of this study is to compare the performance of hybrid air-conditioning systems at building and district scale in the tropics. For this, we gather operational data of an office with a hybrid airconditioning system in Singapore and analysed the energy saving potential of separating latent and sensible cooling processes at the district scale. The effect was quantified with a virtual case study composed of 11 office buildings in Singapore. We compared decentralized and centralized options for the supply of High-temperature and Low-temperature chilled water. For the case study, the cooling consumption per area at the district scale can be potentially reduced by 24% in comparison to the current supply system at the building scale. A further study is necessary to determine optimal operation strategies and associated costs of hybrid air-conditioning systems at the district scale.
