Experiments were carried out in four naturally ventilated offices to measure the indoor environmental parameters such as air velocity, turbulence intensity and air temperature at three vertical levels, Air change rates for various indoor and outdo
The house dust mite inhabits bedding and soft furnishings in homes. It is implicated as a major cause of allergic asthma. Maintenance of indoor humidity below a level of 7 g/kg inhibits the growth of the mite population.
The purpose of this study was to carry out a mathematical modelling analysis of the effect of indoor pollutant source strengths and ventilation rates on the concentration of pollutants.
The ventilation rate in a building depends on many things, one of which is the air temperature. The air temperature in turn depends in part on the ventilation rate.
In well insulated buildings the ventilation heat is sometimes higher than the heat losses by transmission. For a air change rate of 0,8 per hour the specific heat flux must be calculated with 25 w/m², so heat recovery can save some energy.
The study deals with the theoretical and experimental simulation of gas leaks in buildings.
The amounts, quality and factors affecting of dust accumulation in supply air ducts of eight nonindustrial buildings were studied.
This paper reports the results of humidity and ventilation measurements in occupied residential buildings to study the effect of airborne moisture movement on condensation risks.
Draughts due to air inlets are one of the problems to be solved for improving the global performance of mechanical ventilation systems.
A new method for linking results of detailed air flow pattern calculation with multizone models. | 1992 | English
Multi-zone models are a common tool for calculating air and contaminant exchange within rooms of a building and between building and outdoors.
Avery largeelectronics factory had beencompletely refurbished, and new mechanical ventilation systems installed.
A humidity controlled exhaust fan have been tested during the winter season 1991/2. The test have been carried out in a detached one storey house with a flat roof.
Improved ventilation combined with energy efficiency in naturally ventilated houses. | 1992 | English
Modern one-family houses in Scandinavia built before 1980 are often naturally ventilated and heated by electric baseboard heaters. The overall supply of fresh air is often inadequate during the heating season in many of these houses.
The new building and HVAC technology was used when an EBES multistorey residential building was built in Helsinki.
This paper deals with the problem of the weather influence on ventilation rate for naturally ventilated buildings with purpose provided openings and vertical shafts.
Due to the complexity in describing the simultaneous effects of a number of factors that influence the climate of an attic space it has proven to be difficult to make simulations of it.
