Abstract
The crucial impact on the indoor air quality in technological rooms, including boiler plant buildings, is made by operation of technological devices and ventilation systems. Therefore, the distribution of air temperature and velocity in these rooms mainly depends on location and heat gains generated by combustion devices, as well as emplacement of air supply and air exhaust elements. The temperature and airflow volume of supplied air is also an issue, because the indoor environment parameters are formed by the flow of air in the working area. Determination of the impact of physical factors on the thermal environment in a room is possible using an analysis of the air temperature and velocity. This issue is vital in terms of necessity to maintain the adequate heat conditions in the working area. Therefore, basing on the experimental measurements and numerical calculations (made in DesignBuilder software), the distribution of air temperature and velocity was analyzed in the selected industrial boiler room, located in the Lodz city, in Poland. The results obtained were compared with the recommended and limit values in the industrial buildings.
Highlights
The issue of distribution of air temperature and velocity has been repeatedly studied and discussed for non-residential buildings [1,2,3], there is lack of information about industrial boiler rooms
There are publications on indoor air quality in industrial buildings, where the internal conditions are significantly affected by the operation of technological equipment, and related to the estimation of thermal comfort of employees [4, 5], and the functioning of industrial ventilation [6, 7]
The location of PA1 was between fluidized-bed furnaces, while PA2 and PA3 were on the communication route. It was observed, that at 23.30°C of outdoor air temperature, the air temperature in the room increases of approximately 0.63 K/m along with height, and it was from 20.36°C to 28.86°C in the work zones
Summary
The issue of distribution of air temperature and velocity has been repeatedly studied and discussed for non-residential buildings [1,2,3], there is lack of information about industrial boiler rooms. There are publications on indoor air quality in industrial buildings, where the internal conditions are significantly affected by the operation of technological equipment, and related to the estimation of thermal comfort of employees [4, 5], and the functioning of industrial ventilation [6, 7]. Regarding the recommended air temperature and velocity, there is a lack of studies, that can be used as a guideline for the design of this type of rooms
