Utilising renewable energy sources, such as a ground source heat pump, contributes to energy savings, reducing operating costs and CO2 emissions. However, a faulty installation can lead to incorrect operation, necessitating a comprehensive HVAC system modernisation for proper functioning. The paper presents examples of design and operational errors in such installations, based on the actual HVAC system with a ground source heat pump and a vertical ground heat exchanger in the building of the Primary School in O\u017carowice, Poland. The building inventory and analysis of the existing HVAC system revealed issues related to the improper functioning of the heat pump installation and ventilation system, as well as irregularities in their design and the selection of devices in respective installations. The possibility of optimising the operation of the existing system was indicated by, among others, expanding the ground heat exchanger installation and replacing current heat pump units with ones that are better suited to cover the building\u2019s heat demand. Also, upgrading air handling units with ones equipped with heat exchangers of higher efficiency was recommended.<\/p>\n","protected":false},"featured_media":0,"parent":0,"menu_order":0,"template":"","meta":[],"tags":[433,3269,4169,4171,4168,1144,4192],"tematyka":[4069],"class_list":["post-21197","artykul","type-artykul","status-publish","hentry","tag-ground-heat-exchanger","tag-ground-source-heat-pump","tag-hvac-system","tag-modernisation","tag-optimisation","tag-renewable-energy-sources","tag-school-building","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":["STANIS\u0141AW KOCIK","PIOTR CIUMAN"],"ptb_artykul_text_2":"10.36119\/15.2024.2.3","ptb_artykul_numer_miesi_cznika":"02\/2024 Instal pp.28-35","ptb_artykul_info_autor":"Stanis\u0142aw Kocik, MSc https:\/\/orcid.org\/0009-0002-5391-9750, stanislaw.kocik@polsl.pl;\r\nPiotr Ciuman, PhD https:\/\/orcid.org\/0000-0002-2691-1588 \u2012 Silesian University of Technology, Faculty of Energy and Environmental Engineering, Department of Heating, Ventilation and Dust Removal Technology, Gliwice, Poland.
