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. Keywords: energy saving in heat supply, resource saving, thermal resources saving, economical modes of heating, efficient modes of ventilation, control of thermal conditions in the building, optimization of thermal conditions.
