Design of ventilation routes and indoor air quality in houses using a passive ventilation system. | 1999 | English
Isolation rooms for Tuberculosis in fifteen hospitals have been surveyed and measured in twophases. In phase 1 the isolation rooms in seven hospitals were checked ater the hospitalsrenovation construction had been finished.
Design methodology and economic evaluation of central-fan-integrated supply ventilation systems. | 1999 | English
Residential ventilation systems can be categorized as supply, exhaust, or balanced systems.This effort focused on establishing a design methodology for central-fan-integrated supplyventilation systems.
In order to estimate air change rates (ACH) on Natural Ventilation (NV) processes a number of factors should be known as general and openings dimensions, pressure distribution over the facades, internal heat sources (or sinks) and head losses.
Ventilation air intake - first line of defence against an unfavourable outdoor climate. | 1999 | English
The ventilation air intake (louver) is the first line of defence against an unfavourable outdoor climate.
Microbial investigations and allergen measurements in ground-coupled earth-to-air heat exchangers. | 1999 | English
Different ground-coupled earth-to -air heat exchangers have been constructed in many residential and occupational buildings in Switzerland to precool or preheat the incoming air. Many technical and energetic facts favour such systems.
Factors influencing effectiveness of ultraviolet germicidal irradiation for inactivating airborne bacteria: air mixing and ventilation efficiency. | 1999 | English
As a result of the recent resurgence in tuberculosis incidence, there has been increased interestin using ultraviolet germicidal irradiation (UVGI) of room air to reduce exposures toinfectious agents.
Formaldehyde (FA) adsorption, including that in the presence of water vapours, has been evaluated on adsorbents of various nature and porous structure.
Experimental measurements and characteristics of the supply air "ventilated" window. | 1999 | English
A currently unresolved problem in building design in the paradox between increasing demand for good thermal insulation, and the requirement for ample levels of ventilation, to maintain a healthy indoor environment.
Numerical determination of the effective depth for single-sided natural ventilation. | 1999 | English
This paper describes a numerical method for the determination of the effective depth of fresh air distribution in rooms with single-sided natural ventilation. The numerical method involves predicting air flow and the local mean age of air.
Effects of ultraviolet germicidal irradiation of room air on airborne bacteria and mycobacteria. | 1999 | English
As a result of the recent resurgence in tuberculosis (TB), there has been renewed interest inengineering controls to reduce the spread of TB and other airborne infectious diseases in highrisk settings.
It is recommended to keep the ventilation filters dry. However there are manyventilating systems that cannot fulfil this requirement all the time.
Indoor air quality in museums and historical buildings in St Petersburg and in north-west region of Russia. | 1999 | English
This presentation deals with the problem of achieving stable microclimate in old buildings ofSt Petersburg - such as churches, museums and palaces.
Indoor air quality is decreasing year by year. It is very necessary to find a kind of efficient cleaner to improve the indoor air quality. Two kinds of cleaners were tested. Both of them were made in China. Four simulated chambers were used.
Classrooms in New Zealand schools are mostly low rise buildings with natural ventilationdesigns, sized for summer cooling.
Monitoring indoor relative humidity fluctuations associated with intermittent operation of air conditioners. | 1999 | English
In residential buildings, air-conditioners are usually operated in intermittent mode. Thisintermittent mode may complicate many aspects of indoor environments.
Evaluation of electrostatic precipitator performance for submicron particle size range. | 1999 | English
The fractional collection efficiency (FCE) tests of a commercially available two-stageelectrostatic precipitator (ESP) have been performed for six flow rates.
Reduction of microorganisms by HVAC system filters and analysis of the microorganisms passing through the filters. | 1999 | English
k order to determine the amount of micro-organism present before and after the filters ofHVAC systems, 6 systems in 5 buildings were monitored every 2 weeks for one year.
Measurement of ventilation, air distribution and inter-zonal air flows in a 4-storey historic building using a passive tracer gas technique. | 1999 | English
Air temperature, air humidity and ventilation has been measured in a Swedish baroque castle. Results are presented for a measurement campaign comprising four periods under varying climatic conditions.
With a diameter of 320m, and a height of 50m the Millennium Dome is one of the World's largest enclosed spaces, probably the largest among those intended for public use.
