Abstract:
The paper presents a method of calculating the heat energy loss from the room through double and triple glazing.
In this article algorithms of calculation of losses of energy through the processes of conduction, convection
and radiation heat transfer. The article shows that the replacement of the standard double-glazed window
(total thickness of the double-glazed 24 mm) with the upgraded triple-glazed window (total thickness of the
upgraded glass 47 mm) leads to a reduction in heat energy losses by at least 50 percent; at the same time, with
an increase in the difference between the temperature of the street and the temperature of the room, it leads to
an increase in thermal energy savings. The article shows that the loss of thermal energy through the Windows
is not dependent on the thickness of the glass, but there is a strong dependence of the flow of thermal energy
going through the Windows into the street, the number of glasses in the glass and the distance between the
glasses. The given article technique allows you to quickly calculate the energy loss through 1 m2 of doubleglazed
glass; knowing the total area of Windows in the room, you can calculate the total energy loss through
all the Windows and, if necessary, adjust the supply of heat energy to the room: for example, increase or decrease
the number of ribs of heating batteries.
