Research of development of energy-saving and electrically-heated windows

Abstract

The article describes the technique and presents the results of research into the properties of prototypes
of electrically heated double-glazed windows. The types of energy-saving layers of double-glazed
windows are considered: K-coating and I-coating. Comparison of thermal characteristics of windows
with energy-saving glasses and with ordinary double-glazed windows was performed, which showed
that a single-compartment glass unit with energy-saving glass is more effective than a double-glazed
unit. In this case, double glazing with I - glasses are more energy efficient than with K - glasses. The
mechanical properties and heat resistance of tempered glass are studied, which depend on the degree of
quenching. The process of injecting inert gases, argon or krypton into the chambers between the glasses,
is considered to reduce heat loss from convective heat transfer. This procedure improves the characteristics of light-transmitting structures with an energy-saving coating. Thermal fields in the glass plane
are also analyzed. The possibility of measuring the characteristics of thermoelastic states arising during
the heating of a glass unit is demonstrated. When conducting studies of electrical and thermophysical
characteristics of insulating glass units, leakage currents, the power of insulating glass units at operating
temperature and the resistance of conductive paths were measured. This article discusses the advantages
of using energy-saving glasses, as well as the scheme of action of energy-saving glass in summer and
winter. Energy-saving glass is a new turn in a variety of programs to reduce heat losses and can be used
for energy saving in residential and industrial buildings.
