Study on Distribution and Deposition of House Dust by Different Ventilation Systems in a Full-scale Residential Room | 2015 | English
Impact of Clothing, Breathing and Body Posture on the Shaping of a Thermal Plume above a Human | 2015 | English
The impact of clothing, breathing and body posture on the thermal plume above a thermal manikin was investigated.
Effects of Vent Configuration and Span Number on Greenhouse Microclimate under Summer Conditions in Eastern China | 2015 | English
The effects of vent configuration and span number on the microclimate in multi-span greenhouses were investigated.
Experimental and Numerical Investigation on Airflow and Climate in a Real Operating Theatre under Effective Use Conditions | 2015 | English
In the present study microclimate and airflow patterns in a real operating theatre (OT) under effective use conditions are investigated.
Evaluation of Interaction and Blockage Effects for Multi-fan Units used in Public Transport HVAC Systems | 2015 | English
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.
Air Tightness of Ventilation Ductwork in Recently Built Low-Energy and Conventional Houses | 2015 | English
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.
A Novel Method for Thermostat Set Point Prediction for Energy Savings and/or Better Human Thermal Comfort - A Zonal Modelling Approach | 2014 | English
Very often the set point temperature is selected to satisfy comfort requirements and/or to save energy consumption in buildings.
The Confinement Effects on Jet Kinetic Momentum Flux Quantified by Measuring the Reaction Force | 2014 | English
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.
Effect of Opening the Sash of a Centre-Pivot Roof Window on Wind Pressure Coefficients | 2014 | English
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.
Experimental Investigation of Assumptions Used to Quantify Airflows through a Window under Cross Natural Ventilation | 2014 | English
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.
Calculating the Intensity of Ventilation in Classrooms on the Basis of Measured Concentrations of Carbon Dioxide in Slovakia - Case Study | 2014 | English
Air quality in a classroom is very important.
Air change rate is often used as an important characteristic of indoor environmental quality, which significantly impacts human health.
Capture and Containment Efficiency of the Exhaust Hood in a Typical Chinese Commercial Kitchen with Air Curtain Ventilation | 2014 | English
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.
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.
Potential of Night Ventilative Cooling Strategies in Office Buildings in Spain - Comfort Analysis | 2014 | English
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.
Ventilative Cooling of Residential Buildings - Strategies, Measurement Results and Lessons Learned from Three Active Houses in Austria, Germany and Denmark | 2014 | English
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
A Naturally Ventilated Efficient Residential Building under the Impact of Climate Change | 2014 | English
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.
Time-averaged Single Sided Ventilation Rates and Thermal Environment in Cooling Mode for a Low Energy Retrofit Envelope | 2014 | English | 16 pp
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.
National Survey on Ventilation Systems and the Health of Occupants in Japanese Homes | 2014 | English
The indoor environmental quality and health of occupants in approximately 5000 dwellings were investigated by questionnaire covering the whole of Japan.
