[0001] This utility model relates to the field of heating technology, specifically a phase change heat storage device based on building heating. Background Technology

[0002] Hot water storage tanks in heating systems primarily function to mitigate instantaneous pressure changes and eliminate water hammer. They also store heat during off-peak electricity hours and play a crucial role in balancing system heating temperatures and extending the lifespan of key components. Intelligent control of hot water storage tanks can improve the comfort of living spaces during heating and reduce operating costs.

[0003] Currently, the thermal storage devices on the market use sensible heat storage methods with water as the main medium. For example, a corrosion-resistant hot water storage tank disclosed in the authorized publication number CN214581868U includes a hot water storage tank, a controller, an inlet pipe, an outlet pipe, and a corrosion inhibitor tank. However, the applicant found that the water temperature is a linear curve and is not easy to control. To meet the stability and comfort of heating, a large amount of medium needs to be stored. The above problems directly lead to drawbacks such as complex control methods, large storage medium containers, limited building space, and increased initial investment costs. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figures 1-4 This utility model provides the following two technical solutions:

[0023] First implementation: A phase change heat storage device based on building heating, including a hot water storage tank inner liner 1 and a hanging assembly. The hot water storage tank inner liner 1 has a thickness of 1.5mm, is made of stainless steel, has a net volume of 1000 liters, a diameter of 1000mm, and a height of 1300mm. The hot water storage tank inner liner 1 is connected to an inlet pipe 2 and an outlet pipe 3. The hot water storage tank inner liner 1 has a five-layer phase change heat storage assembly with the same structure.

[0024] The inner tank 1 of the hot water storage tank is connected to an external insulation layer 4, which is a polyurethane foam insulation layer. The outer shell 5 is connected to the outside of the insulation layer 4. The top of the outer shell 5 is connected to a cap 6 covering the inner tank 1 of the hot water storage tank. The cap 6 is a stainless steel cap, which is sealed by a flange and the flange is connected by stainless steel bolts.

[0025] The phase change thermal energy storage component includes two screen plates 9 arranged vertically. Each layer of the phase change thermal energy storage component has two screen plates 9. Through holes 14, each 10mm in diameter, are evenly distributed on the screen plates 9 to form flow channels in the vertical direction. Connecting rods 10 are evenly connected between the upper and lower screen plates 9 to connect them together. Positioning cylinders 11 are evenly distributed on the top of the top screen plate 9. Positioning cylinders 13, with the same structure as positioning cylinders 11, are evenly distributed on the bottom inner wall of the inner tank 1 of the hot water storage tank. Bottom rods 12, matching both positioning cylinders 11 and 13, are evenly distributed on the bottom of the bottom screen plate 9. The bottom rod 12 on the bottommost screen plate 9 can be inserted into positioning cylinder 13, while the remaining bottom rods 12 are inserted into... The five-layer phase change thermal storage components can be movably placed inside the inner tank 1 of the hot water storage tank by inserting the positioning cylinder 11 into the lower phase change thermal storage component. The sieve plate 9 has evenly distributed circular holes 15 with a diameter of 110mm. The bottom of the sieve plate 9 is evenly provided with a support 17 located below the circular holes 15, and the phase change thermal storage module 16 is placed on the support 17 and fits in close contact with the circular holes 15. The support 17 makes the phase change thermal storage module 16 have a larger contact area with water, which can better exchange heat. There are a total of 300 phase change thermal storage modules 16, each module weighs 2 kg, and the total thermal storage capacity is 200 MJ. Each layer of phase change thermal storage components has 60 phase change thermal storage modules 16. In order to facilitate the lifting of the sieve plate 9, a fixing hole 18 is provided in the middle of the sieve plate 9.

[0026] The lifting assembly includes a vertically arranged electric guide rail 19, the output end of which is connected to a horizontally arranged electric guide rail 20, the output end of which is connected to a vertical rod 21, and both ends of the vertical rod 21 are equipped with electric telescopic rods 22. The output ends of the electric telescopic rods 22 are connected to L-shaped support rods 23. The electric guide rail 19 drives the electric guide rail 20 to rise and fall, and the electric guide rail 20 drives the vertical rod 21 to move laterally, so that the electric telescopic rods 22 can drive the support rods 23 into the required fixing holes 18 and then abut against the fixing holes 18. At this time, the bottom of the screen plate 9 can be supported by the support rods 23, so that it is relatively stable when lifted, so as to facilitate the removal of the heavy phase change heat storage components and the periodic cleaning of surface scale.

[0027] A temperature control sensor probe interface 26 is provided on the water outlet pipe 3 to facilitate the connection of the temperature control sensor probe and to detect the water temperature at the water outlet pipe 3.

[0028] The end cap 6 is equipped with an exhaust pipe 7 and a safety valve interface 8. By installing a safety valve, the purpose of explosion prevention is achieved.

[0029] The second implementation method differs from the first implementation method in that: the bottom of the inner tank 1 of the hot water storage tank is provided with a 100mm high round leg 24, and the round leg 24 is provided with a grid-like reinforcing rib 25. The two sides of the inner tank 1 of the hot water storage tank are provided with lifting lugs 27 at a height of 900mm to facilitate lifting the inner tank 1 of the hot water storage tank. A drain outlet is provided on the bottom side of the inner tank 1 of the hot water storage tank.

[0030] Furthermore, all contents not described in detail in this specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used. All electrical components mentioned herein are powered and controlled by existing technologies.

[0031] In use, the bottommost rod 12 is inserted into the positioning cylinder 13 for positioning, and the other bottom rods 12 are inserted into the positioning cylinder 11 for positioning. In this way, all five phase change heat storage components can be movably installed in the inner tank 1 of the hot water storage tank. The heat storage capacity is improved by the phase change heat storage module 16. When it is necessary to clean the surface scale, the end cap 6 can be removed, and then the support rod 23 can be lowered so that the support rod 23 can abut against the fixing hole 18 and support the bottom of the sieve plate 9. In this way, the sieve plate 9 can be moved up stably and placed on the ground. Repeat the above steps to remove the sieve plate 9 completely and clean the sieve plate 9 and the phase change heat storage module 16.
