House dust contamination has recently become an important issue in the residential indoor environment. This study evaluated ventilation systems for removing house dust efficiently in a full-scale residential room.
Yang Lu, Jing Liu, Hiroshi Yoshino, Rie Takaki, Genta Kurihara
The impact of clothing, breathing and body posture on the thermal plume above a thermal manikin was investigated.
Barbara Koelblen, Anna Bogdan
The effects of vent configuration and span number on the microclimate in multi-span greenhouses were investigated.
Keshi He, Dayue Chen, Lijuan Sun, Zhenyu Huang, Zhenglu Liu
In the present study microclimate and airflow patterns in a real operating theatre (OT) under effective use conditions are investigated.
Carla Balocco, Giuseppe Petrone, Giuliano Cammarata, Pietro Vitali, Roberto Albertini, Cesira Pasquarella
A specific type of centrifugal fan named the "squirrel-cage" is broadly used in parallel configurations within an evaporator unit of HVAC systems for public transport.

The air tightness of ventilation ductwork was measured in two recently built low-energy houses and in two conventionally built houses in the summer of 2013. The ducts and components were metal in three houses and plastic in one house.

This paper presents results from an on-going project concerning new design procedures for mechanical ventilation systems with low energy use. Conventional constant air volume (CAV) systems are usually balanced using flat plate dampers.

Very often the set point temperature is selected to satisfy comfort requirements and/or to save energy consumption in buildings.
Yao Yu, Ahmed Cherif Megri
A turbulent jet is the most important flow element in mechanical ventilation. Mixing ventilation is based on the properties of turbulent jets. By entrainment into the jet the ambient air is set into motion.
Taghi Karimipanah, Mats Sandberg
This paper describes the effect of outward opening the sash of a window on local and overall wind pressures. Wind tunnel experiments were used for the purpose of evaluation.
Ahsan Iqbal, Hans Wigo, Per Heiselberg, Alireza Afshari
As natural wind is continuously fluctuating in both speed and direction, quantifying instantaneous wind-driven natural ventilation rate can be difficult, and often an average effect is used to stabilize the fluctuations.
Ryan Meyer, Gang Tan
Air change rate is often used as an important characteristic of indoor environmental quality, which significantly impacts human health.
Pok Lun Cheng, Xiaofeng Li
In typical Chinese commercial kitchens, the large amount of heat and moisture that is generated must be removed. The ventilation and energy consumption rates can be huge.
Angui Li, Yujiao Zhao, Zhihua Wang, Ran Gao
This paper reports an investigation into the ability of the air supply in non-unidirectional cleanrooms to aid recovery from episodes of airborne contamination, and minimise airborne contamination at important locations.
W. Whyte, S. Ward, W.M. Whyte, T. Eaton
Night ventilation has been applied successfully to many passively-cooled or low-energy office buildings. This paper analyses the thermal comfort achievable in office buildings in Spain according to European standard EN 15251:2007.
Olatz Irulegi, Álvaro Ruiz-Pardo, Antonio Serra and José M. Salmerón
The thermal comfort of the “Home for Life” dwelling in Denmark, the “LichtAktiv Haus” in Germany and “Sunlighthouse” in Austria is investigated with a particular focus on the control strategies and the role of solar shading and natural ventilation
Peter Foldbjerg, Thorbjørn Asmussen and Peter Holzer
According to researchers, climate change is inevitable in the 21st century. As far as Greece is concerned, this climate change will be related to an increase in ambient surface temperature and to a decrease in annual precipitation.
Theofanis Psomas, Peter Holzer and Mattheos Santamouris
Non-invasive, scalable, building retrofit solutions are very attractive deep renovation techniques to improve energy efficiency in existing buildings; this includes natural ventilation for cooling due to the low impact nature of the installation.
Paul D O’Sullivan and Maria Kolokotroni
The indoor environmental quality and health of occupants in approximately 5000 dwellings were investigated by questionnaire covering the whole of Japan.
Kenichi Hasegawa and Hiroshi Yoshino
