Abstract

The application of a home made, triple hot-wire system in indoor air flow measurements is presented. Both the anemometer and sensor have been developed at Athens University with the aim to provide a reliable, research tool of reasonable cost, simple construction, and satisfactory performance. All three velocity components above a threshold of 10 cm s−1 can be measured. The system is also equipped with two thermometers for measuring the mean and fluctuating air temperature and for providing a means of temperature compensation of the hot wires’ signal. After evaluation of the system in the laboratory, it was used in the measurement of the velocity profile of flows driven by the temperature difference between two internal zones. The implied accuracy of the method allows for its integration with measurements of air volume exchange rates between internal zones, as estimated by tracer gas techniques.
