The Effects of Warm Air Heater on the Dispersion and Deposition of Particles in an Enclosed Environment
Abstract Warm air heaters are now widely used in enclosed environments, either as primary or auxiliary heating facilities. However, the influence of these heaters on the indoor air quality has received scant attention, and the currently available data is insufficient. Therefore, this study experimen...

| description | Abstract Warm air heaters are now widely used in enclosed environments, either as primary or auxiliary heating facilities. However, the influence of these heaters on the indoor air quality has received scant attention, and the currently available data is insufficient. Therefore, this study experimentally investigated the particle concentrations, air velocity, temperature, and relative humidity in a storeroom equipped with a warm air heater. To assess the effects of the heater on the dispersion and deposition of 0.3, 0.5, 1.0, 3.0, and 5.0 µm particles, we analyzed 18 scenarios with various settings for the output power and outlet orientation. The results indicated higher particle deposition rates when the heater was operating. Furthermore, the particles’ decay rate loss coefficients increased with the heater’s output power and the particles’ proximity tothe heater’s air outlet but were also influenced by the direction of the warm air flow. |
