A spring sleeve type variable volume solar water storage tank

Abstract

The invention discloses a spring sleeve type variable volume solar hot water storage tank, which comprises a water storage tank. The water storage tank is provided with a variable capacity tank, and the top of the variable capacity tank is fixed to the top of the water storage tank. , the bottom of the variable capacity tank is a movable bottom shell that can slide along the height direction of the water storage tank, and a spring sleeve is arranged between the movable bottom shell and the top of the variable capacity tank; An on-off valve is installed on the mouth; the top of the variable capacity tank is provided with a water supply pipe for connecting with the water supply end of the solar collector, and one side of the variable capacity tank is provided with a water supply pipe and a water return port for connecting with the solar collector. Connect the return pipe, and the other side is provided with a water supply pipe for supplying to the user; the bottom and top side of the water storage tank are respectively provided with a drain pipe and an exhaust pipe. The invention can adjust the heat storage capacity according to actual needs, enhances the flexibility of water storage, and greatly meets the needs of users.

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
