New forecast control of heat for heating

Abstract

In many existing buildings, the reduction in energy consumption has already been made by carrying out the thermal modernization of the building envelope. Therefore, other renovation measures, aimed at further increasing the level of energy efficiency in such a buildings, will focus in particular on improvement of control and automation of the processes of supply, as well as storage and use of energy.
This paper presents the field results of applying forecast control of heating system, which can be easily employed in existing buildings (time of installation in existing buildings: below 2 hours) and may work with existing, widely used weather controller. The new methods (applied in forecast controller) used for the creation of real energy model of the building (energy characteristics of buildings and their heating systems) and for forecast of heat power for heating are presented. The field research was conducted for a multi-family building located in Poland for part of a single heating season. The analyzed multifamily building in the first part of research was regulated only by a traditional weather-based controller, whereas forecast control system was used in the second part of research. The application of the proposed forecast control allowed decreasing the supply temperature of heating medium, lower the heat power supplied and in such a way generate energy savings of above 10%.
