Abstract

Considering the hot weather annually and thus leading high cooling demands in Guangdong-Hong Kong-Macao Greater Bay Area (GBA) of China, a novel distributed cooling production system powered by gas-electric hybrid energy was proposed. The thermal, economic and environmental performances of this process were assessed. The conventional electric air conditioning cooling system was employed as a reference system to demonstrate the benefits of this proposed system. It was found that the total energy efficiency and energy saving rate of this newly proposed system were 201% and 27.8%, respectively, while the payback period was around 3 years. The CO2, SO2 and PM reduction ratios were found to be 54.8, 69.4 and 70.5%, respectively. Further discussion on the safety controlling methods has been included in order to reduce maintain operation cost and to achieve intelligence of this prototype
