Natural-forced automatic device in order to keeping diffuser's position and constant diffusion velocity for thermal stratification in thermal storage tank

摘要

The stratification diffuser according to the present invention is installed and used for the purpose of storing and using hot water when there is a mismatch between the demand and supply of heat in district heating, etc., for the purpose of maximizing the use of effective energy in medium and large storage tanks. The water varies in density with temperature, and the density of the hot water is lighter than that of the low temperature water, so it is related to the improved diffuser installed inside the diffuser. Accordingly, the present invention relates to a flow type diffuser capable of automatically adjusting the up and down position by no power and maintaining a high stratification degree by constantly maintaining a constant spray speed at the end of the diffuser according to the flow rate of hot water supplied to the heat storage tank.
