Сезонні акумулятори тепла в схемах теплопостачання приватних житлових будинків. (Ukrainian)

The article is devoted to the choice of a seasonal heat accumulator (SHA) for the primary circuit of a heat pump in the heating and hot water supply system of a private house. In Ukraine, the implementation of state-of-the-art efficient energy storage systems in individual housing construction is constrained by the significant cost of equipment and the lack of state support. However, the steady increase in energy tariffs encourages households to look for acceptable options for SHA among what is offered to consumers in the domestic market of technologies and equipment for renewable energy. The transition to renewable energy sources (RES) is accompanied by an additional energy task – the coordination of unstable RES with the load, which also varies during the day and throughout the year. This is especially true for countries that need heating in the cold season. The power generated by most RES depends significantly on changing natural phenomena. The article proposes the German technology of ice heat accumulator – Wärmepumpe Eisspeicher-System. It was developed by Viessmann as a reaction to the German Environmental Protection Agency's ban on ground source heat pumps, both collector and ground probes. In the conditions of densely populated Germany and the high cost of land, the alienation of large areas of it for the arrangement of the primary circuits of HP is unacceptable - the land is withdrawn from agricultural circulation – and is contrary to state interests. Therefore, the use of ice batteries as the primary circuits of HP removes the problem of both direct and indirect environmental damage. The calculations of the heat balance of the primary circuit of the Eisspeicher-System heat pump for the coldest month of the heating period presented in the article confirm the possibility of functioning of the heating system and hot water in monovalent mode.
