The problem of dissipating cooling loads through the TABS system in this kind of building was identified. The use of ventilation air to dissipate a portion of these loads was proposed, and simple control algorithms integrating the TABS system and the air system were compared. A simulation model of the system\u2019s operation throughout the year was developed using the TRNSYS17 program as a research tool.
\nThe optimization problem of selecting energy-optimal control was solved, where the constraints were to meet thermal comfort conditions (operative temperature within the required range), and the objective function was to minimize the primary energy demand of the HVAC system throughout the year. TABS system control algorithms were based on: heating and cooling curves determined with the Unknown-But-Bounded (UBB) method and switching temperatures were determined with an original author\u2019s method.
\nCalculations were carried out for a case study \u2013 a lecture room in an educational building. It was demonstrated that only the integration of the TABS system with ventilation, also acting to dissipate part of the thermal loads TABS+VAV (Variable Air Volume), allows maintaining the operative temperature within the required comfort range for 83% of the occupation time for the most favorable comfort control variant. In the case where ventilation only served hygiene purposes \u2013 TABS+DCV (Demand Control Ventilation), the time of operative temperature within the comfort range was only 14% of the room\u2019s occupation time for the most favorable control variant.<\/p>\n","protected":false},"featured_media":0,"parent":0,"menu_order":0,"template":"","meta":[],"tags":[2840,4202,4199,1929,3407,4203,2842],"tematyka":[4069],"class_list":["post-21344","artykul","type-artykul","status-publish","hentry","tag-dcv-en","tag-energy-efficient-control","tag-tabs","tag-thermal-comfort","tag-trnsys","tag-users","tag-vav-en","tematyka-heating-ventilation-air-conditioning-hvac","has-post-title","has-post-date","has-post-category","has-post-tag","has-post-comment","has-post-author",""],"ptb_metabox":{"ptb_artykul_text_1":["KATARZYNA PA\u0141ASZY\u0143SKA","KAROL BANDURSKI","MIECZYS\u0141AW POROWSKI"],"ptb_artykul_text_2":"10.36119\/15.2024.3.4","ptb_artykul_numer_miesi_cznika":"03\/2024 Instal pp.31-38","ptb_artykul_info_autor":"mgr in\u017c.
