There are many high-temperature heat sources in industrial buildings

and the formed thermal plume has a significant impact on air distribution. In this study

using a new energy battery material production workshop as an example

six air supply speeds and six air supply port heights were used to study the interaction of a multi-heat source heat plume and supply air jet

as well as the effect of the interaction on the thermal environment of an industrial building. The results show that the multi-heat source coupled heat plume is dominated by the high-temperature heat source

the plumes close to each other form a concentrated entrainment space

and the maximum axial velocity is approximately 0.64 m/s. Using a thermal plume to guide the upward movement of air distribution

high-temperature air can be quickly exhausted to effectively improve the thermal environment of the building work area. Reducing the air supply speed can reduce the inhibitory effect on the upstream heat plume. When the air supply speed decreases from 14.80 m/s to 2.96 m/s

the workshop working area temperature decreases from 39.2 °C to 31.6 °C. Reducing the height of the air supply outlet can increase the promotional effect on the upstream heat plume. When the height of the air supply outlet decreases from 5.0 m to 1.7 m

the temperature of the workshop working area decreases from 34.9 °C to 30.3 °C. These results can be helpful for the ventilation design of industrial buildings.
