Method of calculation of thermal loss energy in double and triple glass packaging

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.
