| dcterms.abstract | A building sector requires massive energy demand. By improving the building energy efficiency and becoming more environmental-friendly, a number of economic and environmental attraction approaches can be conducted for future development. Energy consumption is associated with the power consumption and the coefficient of performance (COP) of Heating, Ventilation, and Air Conditioning (HVAC) systems. In this thesis, the renewable energy-efficient technology - seawater heat pump (SWHP) and chillers were introduced to improve the energy performance, especially for the coastal area. Seawater temperature is an important factor to determine the thermal performance of SWHP systems and chillers. Buildings located near the sea can exploit the advantage of using the water sources as a heat source and heat sink. This paper focused on the studies of the heating and cooling systems in Hong Kong. It aimed to use the computer software, TRNSYS, to simulate and design a suitable heating and cooling systems for the coastal communities. The maximum heating load was calculated as 1195.29kW and the peak cooling loads were 3921.45kW for space cooling and 1599.60kW for AHU cooling. Corresponding catalogues were chosen for system sizing and investigated the efficiency of water source and air source heating and cooling system. It is found that water source systems are more efficient than air source systems, which has a higher COP and lower power consumption, and is benefits in economic aspects. | en_US |
