Abstract
Abstract In this study, indoor air quality and thermal conditions were studied under laboratory conditions with the heat load that was located symmetrically or asymmetrically in the room. Diffuse ceiling ventilation (DCV) was adopted to provide cooling and outdoor air to the room. CO2 concentration, room air temperature and air speed were measured in the test chamber. This study gives insight of both thermal comfort and indoor air quality with different heat load levels and load distribution. The results show that the strength, distribution and the type of heat load have a significant influence on air distribution and thermal comfort. In all cases, the performance of the diffused ceiling ventilation was like fully mixed ventilation. The mean air temperature and speed increase with the heat load, as a result, also draught rate increases, which meant the heat load distribution has effect on local thermal discomfort.
期刊介绍：
This is a peer reviewed journal aimed at providing the latest information on research and application.
Topics include:
• New ideas concerned with the development or application of ventilation;
• Validated case studies demonstrating the performance of ventilation strategies;
• Information on needs and solutions for specific building types including: offices, dwellings, schools, hospitals, parking garages, urban buildings and recreational buildings etc;
• Developments in numerical methods;
• Measurement techniques;
• Related issues in which the impact of ventilation plays an important role (e.g. the interaction of ventilation with air quality, health and comfort);
• Energy issues related to ventilation (e.g. low energy systems, ventilation heating and cooling loss);
• Driving forces (weather data, fan performance etc).
