Контроль микроклимата в здании посредством измерения температурного градиента стен

Abstract

In this study, the temperature gradient of walls was analyzed as a parameter for monitoring and controlling the internal temperature of rooms. Experimental data were collected in eight buildings in the Narekatsi district (Yerevan). The measurement results showed that the temperature gradient varies in the range from 13.1°C/m to 30.8°C/m. The maximum value (30.8°C/m) was recorded in the eighth building, while the minimum (13.1°C/m) was in the seventh. It was established that a higher temperature gradient correlates with lower values of internal temperature. Analysis of the relationships between temperature regime parameters revealed that the internal temperature of rooms linearly depends on the external temperature, while the temperature gradient is inversely proportional to the thermal conductivity coefficient, which determines the intensity of heat exchange between the structural elements of the building and the environment. Based on the obtained data, thermal mathematical models were developed that describe the thermodynamic characteristics of the building envelope structures. The derived equations, obtained by methods of graphical analysis, can be used as calculation parameters in building design, allowing the optimization of the internal temperature regime in accordance with regulatory requirements. The results of the study confirm the need for a comprehensive accounting of external and internal temperature loads, as well as the temperature gradient of walls to improve the efficiency of managing microclimatic conditions inside rooms.
