| Abstract |
More than 60% of people all over the world are living in urban areas, and the people and buildings keep spending energy, and it makes excessive problems of global energy system. Currently, lots of attention is being paid for how to design HVAC(heating ventilating air conditioning) system in large-scale and high-rise buildings. Increasing awareness of energy use is main point of this research. HVAC systems' energy characteristics are not clearly identified and understood, so the optimal design of HVAC system is very important. Despite the fact that cold air distribution system, displacement air conditioning system, UFAD(under floor air distribution) system, cooling/heating radiation system, chilled beam system and DOAS(dedicated outdoor air system) have many energy conservational benefits and are being applied in the field in increasing numbers, there is need for fundamental understandings of several energy consumption factor of these HVAC systems. This study investigates the energy parameters of HVAC design that are system input energy, water/air moving equipments(pumps/fans) energy and outdoor air conditioning energy for IAQ. The purpose of this study is to provide the basic data for energy conservation strategies and it is a main target in the development of HVAC system selection/design guideline. |
