| Tartalmi kivonat: | The present paper analyses the thermal comfort conditions of a typical summer day in a popular playground simulated by two micrometeorological models, ENVI-met and RayMan in a Central-European city, Szeged. The thermal comfort conditions of the study area were quantified by the Physiologically Equivalent Temperature (PET). The outputs of the simulations were compared to each other and than they were collated the onsite measurements which were carried out in a sun-exposed and in a shaded point of the investigated area. According to the models, the highest heat load in the selected time intervals occurred in the middle parts of the playground, which were exposed to the sun, while more comfortable conditions could be experienced in the shade of the vegetation and the buildings. Based on the comparison of the measured and modelled data, both models underestimated the real thermal parameters under sun-exposed conditions. However, in the shade RayMan was more accurate, and here the measured and modelled PET values were almost identical. Beside these results, the main positive and negative features of the applied models are also discussed in the paper. |
