Abstract:

The purpose of the study is to reduce the energy consumption of residential buildings with the help of laboratory studies on the improvement of calculation methods, which could specify together the processes of heat transfer and air filtration in the building envelope of the frame-panel type.

Laboratory tests of wall structures of the frame-type switchboard have been carried out with the help of the climatic heat-cold-moisture chamber REOCAM TCM-1000 belonging to the Department of Heat and Ventilation of Industrial University of Tyumen. Two types of skeleton-shield walling fragments have been tested. The experimental data were used to improve the computational model.

As a result of the research, it has been refined and offered to design a thermophysical model of non-stationary heat and mass transfer in external wall structures, allowing to more accurately reflect together the processes under the air filter and heat transfer. Using thermophysical model allows to take into account the heat loss and to perform the selection of efficient materials for wall construction.
