Vol1: Twenty four papers from the tenth AIVC Conference, titles as follows: “Keynote Speech”; “Annex 14 - Condensation and Energy”; “Annex…
This paper describes an experimental study of the buoyancy-driven flow and the associated energy transfer within a closed, halfscale stairwell model. It…
The distribution of wind pressure on a building envelope is governed by the size and shape of the structure and the turbulence characteristics of the wind.…
The air flow within a room, the interchange of air between rooms and the interchange of air between a building and the exterior are topics which until today…
A comparison of three injection manners, step-up, step-down and pulse, for determination of the mean age of air was made by using nitrous oxide and sulphur…
The use of passive perfluorocarbon technique for air flow measurements has been developed and tested. The building and testing of the system took…
This paper describes a simulation program which was developed for the modelling of air-conditioning systems and conditioned spaces in industrial buildings.…
The air exfiltration part of ventilation is often difficult to determine and its part of the energy balance is therefore usually determined as a remainder…
In central units of air heating systems the supply air flow must meet the actual heating demand. Most of central units for air heating systems have only one…
This paper describes the development of a microprocessor-controlled tracer gas system which is capable of collecting a large number of tracer gas samples at…
This paper describes a set of experiments conducted in a three bedroom house in order to identify the leakage distribution of the building and the air flow…
VAV - air conditioning system makes it possible to control indoor conditions even when the heat loads are changing. But this is possible only when each part…
The indoor climate and ventilation were measured in 50 dwellings with various ventilation systems. The health and comfort of people living in the dwellings…
Pressurization, or depressurization, of buildings is a tool to assess the airtightness of building envelopes. A common working pressure is 50 Pa, and the…
Ventilation in a building enables to renew the air it contains by means of a natural exchange of air (depending on weather conditions and climate) or a…
This paper presents and evaluates a new method, based upon tracer gas techniques, for determining interzonal airflows and effective volumes in a multizone…
A tracer gas technique for determining volumes and air flow rates in multi-cell systems with a single tracer gas is considered. Tracer gas is injected in…
Canadian research into residential ventilation and combustion venting revealed that the installed performance of exhaust equipment, ducting passages, and…
A demand controlled air ductwork should be so dimensioned that the flow controllers have good flow and acoustical operation conditions. From the air flows…
Measurement methods based upon multiple tracer gas techniques have become an established branch of the study of air infiltration and interzonal air…
