An Exergy Application for Analysis of Buildings and HVAC Systems

摘要：

The paper presents an extended method for exergy analysis of buildings and Heating Ventilation Air Conditioning (HVAC) systems,according to an energy demand build-up model from the building side to the energy supply side.The HVAC systems comprise thermal energy emission and control system,thermal distribution system,electricity distribution system and local energy conversion system.Energy and exergy that are required by the buildings and the HVAC systems are posed into the external part and classified by different forms of energy carriers.The external part is out of the boundary of the study.The method is demonstrated with a heavy office building equipped with low-temperature heating and high-temperature cooling systems situated in a cold-climate region.Thermal exergy and thermal energy demands of the building and thermal energy and thermal exergy losses occurring in the HVAC systems are discussed to the relevance of exergy analysis of the building and HVAC systems.
