Experimental Investigation of Mean Radiant Temperature Trends for a Ground Source Heat Pump-Integrated Radiant Wall and Ceiling Heating System

Mean radiant temperature (MRT) is one of the six primary factors that determine thermal comfort in a given environment. In this study, average was determined using calculation method based on surrounding surface temperatures and view factors. The present study specifically investigated use calculated temperature, compared to measured for predicting mean vote (PMV) percentage dissatisfied (PPD) parameters. validated by experimental measurements via black sphere thermometer at five different reference points test room, including panels ceiling walls. By global measurements, proposed approach achieved high degree compatibility an accuracy 0.17 °C, which difference between values. results demonstrated reliability procedure calculate designated room; here, straightforward evaluating conditions office room determining optimal location air sensor PMV-controlled systems also proposed. This contributes increasing field research offers knowledge beneficial design optimization indoor environments.
