Overview

The technical solutions for the installation of heat pumps in individual houses are well known, but its integration in the existing systems in dwelling houses is not common. Heat pump technology is referred to as renewable but would have technical, economic and environmental impact on the whole existing heat supply system in a dwelling house. The aim of this article is to investigate the possibility of using heat pumps for supplying heat to the existing residential buildings. This article examines the possibilities to supplement the engineering systems with additional heat pumps. The smallest heat pump end-user group is the dwelling stairwell. The possibility to use heat pumps in a separate apartment has not been analysed. This article analyses the integration of heat pumps for residential heat supply in the building. The primary heat source is the exhaust air or wastewater. All calculations have been made for several real existing dwelling houses in Birštonas town (Lithuania) within the framework of the CONCERTO Eco-Life project. The analysis also provides economic and environmental assessment of the alternatives. This research was supported by EC FP7 CONCERTO program (‘‘Sustainable Zero Carbon ECO-Town Developments Improving Quality of Life across EU - ECO-Life’’ (ECO-Life Project) Contract No. TREN/FP7EN/239497/\"ECOLIFE\"). Tehniskie risinājumi siltuma sūkņu uzstādīšanai privātmājās ir labi pazīstami, bet to integrācija jau esošās sistēmās daudzdzīvokļu ēkās notiek diezgan reti. Siltuma sūkņa tehnoloģiju bieži sauc par atjaunojamo, bet to integrācija daudzdzīvokļu ēkas esošajā siltumapgādes sistēmā sekmē tehnisko, ekonomisko un ekoloģisko izaugsmi kopumā. Darba mērķis ir siltuma sūkņu integrācijas iespēju izpēte esošajās siltuma/sanitārajās sistēmās daudzstāvu dzīvojamās ēkās. Vismazākā telpa, kurā iespējams integrēt siltuma sūkni, ir daudzstāvu ēkas kāpņu telpa. Siltuma sūkņu izmantošanas iespējas atsevišķā dzīvoklī netika aplūkotas. Detalizēti tika analizētas trīs alternatīvas: HP_R1 – siltuma sūknī saražotā gaisa siltuma izmantošana karstā ūdens sagatavošanai; HP_R2 – siltuma sūknī saražotā gaisa siltuma izmantošana telpu apsildei, pieslēdzoties rekuperatora vai mehāniskās ventilācijas sistēmai; HP_R3 – ēkas notekūdeņu siltuma izmantošana siltuma sūknī karstā ūdens sagatavošanai. Alternatīvu analīze un aprēķini tika veikti reālām daudzdzīvokļu ēkām Brištonas pilsētā (Lietuva) projekta CONCERTO Eco-Life ietvaros. Analīzē iekļauti arī alternatīvu ekonomiskie un ekoloģiskie novērtējumi.
