EFFICIENT ENERGY SAVING SOLUTIONS DURING HEAT SUPPLY IN BUILDINGS

Abstract

The article deals with topical issues of energy saving during heat supply in buildings. The authors
have proposed effective measures which reduce power consumption when supplying heat in
buildings, namely, realization of adaptive control of heating in buildings; pulsed weather algorithm
for control of the heating system; optimal mode of intermittent heating of the building; optimum
temperature of the heat transfer agent in the heat networks; energy-saving measures in ventilation
systems. The developed adaptive control of the heating system enables us to compensate the disturbing
effect for temperature conditions of buildings (outdoor temperature), taking into account the actual
thermal performance of buildings and their heating systems. Pulsed weather control algorithm
for the elevator heating eliminates “overheating” of buildings both in a “bad” weather chart and

in the period of its “turning off”. The optimal mode of intermittent heating of the building can be
implemented in various buildings, where reduction in the temperature of indoor air outside working
hours is allowed. This is accompanied by heat energy saving while ensuring the required parameters
of the microclimate during working hours. The efficiency of the optimal mode of intermittent heating
compared to other well-known algorithms of heating systems control is proved. Moreover, the
use of an optimal mode of intermittent heating in case of independent heat sources is justified. The
authors have solved the problem of optimum temperature of the heat transfer agent in the heat networks
that can reduce heat loss during transportation of the heat agent and minimize the energy
costs for its pumping.
