Abstract

The paper focuses on the experimental measurement of the accumulation of hot water storage with its thermal stratificational thermal layers by means created of elementary conical elements. The basic principle of these elements is the automatic distribution of water temperatures according to temperature and volume flow for a specified time of storage of heat energy. This process involves maintaining the thermal stratification at different height levels of the storage tank, which minimizes the process of balancing the hot water. The aim of the experiments was to demonstrate the thermal energy layering in the 1050 l water storage accumulator in 1 hour depending on the different water flow rates from 250 to 1000 l/h from the heat source.
