Development of heat exchanger models (men and women) and the evaluation of thermal interactions influencing people on indoor thermal environment.

Project manager: Anna Bogdan Ph.D. (Eng), D.Sc. (Eng.)

Project summary:

Within the project theoretical models of thermal regulation of a man (men and women) were developed. What is more they were verified in terms of forecasting accuracy in skin temperature and parameters of air in the human environment. Method of thermal interactions simulation which occur in the work rooms used simultaneously by many people was developed. For this purpose, following issues were carried out:
- Series of numerical calculations to check the possibilities and limitations of simulation method usage in thermal interactions in the room, and also to check the reproducibility of obtained results depending on the variant of adopted minor modifications;
- Estimation of individual parameters sensitivity on the accuracy of calculations;
- Assessment of the possibility to accelerate calculations without quality impairment of the obtained results.
Developed models are suitable for the emerging microenvironment evaluation forming around the human body and for testing heat interactions happening between people over short distances from each other (up to approx. 1.2 m). Simplified models characterize by less accuracy of obtained results, however due to the duration of the computations they can be used for calculations in rooms of greater capacity or for overall ventilation and air conditioning solutions, if the assessment is not influenced by the closest human environment.
