A practical experiment to analyse the distribution of air in terms of temperature ratios in a room with heated carpets and the influence on the surrounding environment is performed. Some countries with very low temperatures and high density values require one of the heating procedures to provide human comfort conditions (temperature about 25 °C, humidity around 50%).In this study, it is realistically explored how different types of heated carpets of varying weaves affect the temperature distribution inside the room. Experiments were also conducted at a heat flux value of 120 W/m2, with measurement locations above, near, and distant from the heated surface, as well as at different times (15 and 25 minutes) and height ratios.
The results show that the values of temperature ratio of full pilled carpet are (1.035568, and 1.036934) far from the carpet, and the values are (1.036592, and 1.038641) near the carpet; respectively at 15 and 25 minutes, height ratio of 0.0625 and 120 W/m2.
The values of the temperature ratio of partially pilled carpet increase to (1.04146 and 1.04351) near the carpet, compared to the full pilled carpet under the same conditions.
This is due to the presence of spaces (areas without pile) on the surface of the partially pilled carpet, allowing for easier heat transfer compared to the full pilled carpet leads to an increase in the temperature values.
The partially pilled carpet has a greater impact on the room to be heated by using hot carpets, as it has the highest temperature values and the lowest density values. Empirical correlations have been developed depending on the study operating conditions.
