Abstract: Water storage tank is an important component in solar hot water heating system. The stratification characteristic of water storage tank has a direct influence on the efficiency of solar hot water heating system and hot water discharge amount. A new water storage tank is put forward in this paper; the temperature distribution during discharge process is got, and the temperature in different position in the tank, stratification number, the thickness of thermocline and mix number are analyzed under the conditions of two different flow rates of 1.60 L/min and 4.87 L/min. The use of new stratifier leads to a good stratification effect in two flow rates and the stratification effect in the flow rate of 1.60 L/min is better than that in the flow rate of 4.87 L/min.
