| Summary: | Currently, the successful development of construction industry depends on the improved energy performance of buildings, structures and facilities, as well as on the quality assurance of the indoor climate. In view of the above, designing and operation of buildings should be aimed at the best (optimal) solution of the following objective: to ensure the set-point values of indoor climate serviced by automated climate control systems, against the minimal energy consumption. In regard of its substantive structure, this paper describes the study on the relationship between the individual parameters of indoor thermal stability and the regulatory impact of automatic control systems (ACS). We analyzed the effect of structural room characteristics on the total energy consumption of the airflow processing unit in order to ensure energy saving. The final result is illustrated by numeric simulation with the use of a developed computer program and graphic examples. The proposed method is based on the assumption that the total thermal stability of the «room-ACVS-ACS» system is defined by heat absorption index of a room and the ACS control operation. This follows directly from the back-to-back connection of units corresponding to the room and ACVS in the scheme of automatic indoor climate control. Further study allowed authors to trace the influence of structural characteristics of a room on the total energy consumption needed for air intake treatment. This can be done by applying values of the main walling area. Basing on the developed algorithm, the authors made calculations using the computer program developed in Fortran. As a result a fragments of the program are presented - calculations of the parameters’ values included in the expressions and the total specific energy consumption for heating the air intake during the heating season, under varying room geometry, as well as the graphic illustration of the obtained relationships.
