Abstract

The purpose of the article is to study and analyze the variation of the temperature gradient in industrial premises equipped with mechanical ventilation systems and having a ceiling height greater than 4 meters. In such premises, there is a significant number of thermal layers, and the volumetric airflow depends on a number of factors that can substantially affect the cost and efficiency of the ventilation system. One of these factors is the predefined temperature difference between the supply and recirculated air. In industrial halls where air distribution devices are installed near the ceiling, it is necessary to consider the additional temperature gradient above the occupied zone. To investigate this, an experimental study was conducted. The article presents the results of air temperature distribution measurements. In the examined industrial hall, wind-type diffusers were used for supply air, and adjustable aluminum grilles were used for the exhaust system. Measurements were carried out, and the change in temperature gradient was calculated within the height range of 2 to 7 meters.
