THE MEASUREMENT OF AIR INFILTRATION RATES IN LARGE ENCLOSURES AND BUILDINGS
The paper describes work carried out as part of a research contract funded by the U.K. Department of the Environment and the Commission of the European Communities. The object of the research is to develop a validated method of measuring air infiltration rates in industrial buildings and to use the method to measure ventilation rates in some selected buildings. The following points are discussed: (a) Poor mixing in industrial buildings. Implications of poor mixing for choice of measurement method and interpretation of results. (b) Review of possible measurement methods. Trials of a low cost fuel cell gas analyser designed for measuring ethanol vapour. (c) A computer controlled multipoint tracer gas concentration measurement system using infrared gas analysers and nitrous oxide as the tracer gas. (d) Preliminary results obtained with only natural ventilation. (e) Need to validate method by comparing ventilation rates measured by tracer gas method with mechanical extract or supply rates while depressurizing or pressurizing a test enclosure. Airtightness testing of two industrial buildings in preparation for validation work.
