Spring sleeve-type variable-volume solar energy heat storage water tank

Abstract

The invention discloses a spring sleeve-type variable-volume solar energy heat storage water tank comprising a water storage tank. A variable capacity box is arranged in the water storage tank, the top of the variable capacity box is fixedly connected to the inner top of the water storage tank, the bottom of the variable capacity box is a movable bottom shell which can slide in the height direction of the water storage box, a spring sleeve is arranged between the movable bottom shell and the top of the variable capacity box, an adjusting port is arranged on the movable bottom shell, and a switch valve is arranged on the adjusting port; the top of the variable capacity box is provided with a water supply pipe for connecting with the water supply terminal of a solar heat collector, one sideof the variable capacity box is provided with a water replenishment pipe and a return water pipe connected with the backwater end of the solar heat collector, and the other side of the variable capacity box is provided with a water supply pipe for supplying water to users. The bottom lateral side and the top lateral side of the water storage tank are respectively provided with water discharge pipeand fume discharge pipe. The spring sleeve-type variable-volume solar energy heat storage water tank has the advantages of adjusting the heat collection volume according to the actual demand, improving water storage flexibility, and meeting the demands of the users greatly.

Description

technical field [0001] The invention relates to the technical field of solar heat utilization, in particular to a hot water storage tank whose volume can be changed according to the user's water demand and system water temperature changes. The variable capacity hot water storage tank has high heat utilization effect and flexible water temperature / water volume advantages of control. Background technique [0002] Solar energy is a renewable energy source, which has the advantages of rich resources and no pollution. Most heating areas in my country are rich in solar energy resources, so the use of solar heating is in line with the sustainable development strategy. Solar energy utilization includes hot water supply, heating, etc.; but there are significant solar radiation The volatility is mainly reflected in seasonal and diurnal fluctuations. At the same time, due to the different needs of users, solar hot water supply has a time period, and solar heating presents dynamic change...

AI Technical Summary

Problems solved by technology

However, the existing fixed-capacity storage hot water tank has a large volume, and it is difficult to quickly heat up, so the volume needs to be reduced; at the same time, the solar energy is sufficient in summer, in order to prevent overheating, the existing volume is insufficient, so the volume needs to be increased

It can be seen that the water tank with a fixed volume fails to follow the regularity of solar energy, which will cause inconvenience, and because the difference in water consumption at the user end is not considered, it will cause huge differences in the use of the same product due to different users, affecting the use of users Experience and Quality of Life
