Annotation
The article is devoted to the study of the dynamic parameters of heat transfer processes in the building envelope based on monitoring the temperature of the building envelope inside and outside the building using a microcomputer. The aim of the work is to study the process of heat supply through the outdoor enclosures in summer and to evaluate the accumulated energy in them. The daily dynamic parameters of the heat-transfer process in the building envelope were also studied, as well as the characteristics of heat transfer based on the sun protection panels of the building during the summer insolation peak. The calculation of characteristics of the energy storage system depending on the thickness and material of the enclosing structure has been performed. The author proposed a method of modeling the process of heat transfer through the external enclosing structures based on data of temperature monitoring inside and outside the building walls. The result of evaluation of real characteristics of the energy storage system and their dynamic range of daily changes during the summer maximum insolation is obtained. The dynamic range of changes in the heat loss of the wall of the academic building is at night from 0 to 13.9 W / m2, heat transfer from 0 to – 36.7 W / m2 during the day. An experimental study of the dynamic parameters of heat transfer processes in the enclosing structures of buildings was carried out in the educational building of the Faculty of Informatics and Power Engineering of the PITTU.
