The process of non-stationary heat transfer occurs in outdoor enclosures at a
changing outdoor temperature (mainly). The ability to maintain a relative
constancy of temperature on the inner surface when changing thermal
influences is the most important thermal engineering characteristic of an
external fence.

Objective: Investigation of thermal engineering characteristics of an external fence in
constantly changing conditions of thermal resistance.
Task:
1) It is necessary to install two sets of temperature and heat flow sensors, which are fixed on
the one hand on the inner surface of the fence and on the other hand on the outer surface of
the fence and the relative humidity of the external and internal air, For this it was necessary to
make a hole. The sensors are also covered with a visor so that they are not affected by other
processes.
2) Plotting and analyzing data in the form of a graph with a curved line showing temperature
changes on surfaces.
3) To draw a conclusion about the constancy of indicators in the enclosure, outside and
indoors for one year.
4) Experimental data on thermal properties. The resistance can be compared with the
theoretical ones, which is according to GOST, as the ratio of the layer thickness to the
calculated coefficient of thermal conductivity.

With the help of the heat flux density meter ITP-MG 4.03/X(Y), made by special order by Stroypribor, we will be able to find
out the relative humidity and temperature of outdoor and indoor air, temperature and heat flow on the outer and inner
surfaces of the fence. In parallel with the main task, thanks to endoscopy, we will be able to observe the composition of the
outer fence, which is also interesting.

Methods: The technique consists in determining the thermal resistance in various ways: the
main one in my topic is experimental, because knowing the data on the amplitudes of
temperature and heat flow, we can determine the thermal the resistance of our wall to various
factors throughout the day throughout the year.
