[0025] like Figure 1 to Figure 2 As shown, this embodiment designs a sensible heat storage experimental device, including components such as a fan 1, a heater 5, a sensible heat storage component and a radiator 10. The fan 1, the heater 5, the sensible heat storage component and the radiator 10 are successively connected through a ventilation pipe.

[0027] The heater 5 is a tube structure with a built-in electric heater; the air inlet end of the heater 5 is connected to the fan 1, and the air outlet end of the heater 5 is connected to the sensible heat storage component. When the electric heater is powered on, it can heat the air flow passing through the heater 5.

[0028] The sensible heat storage assembly includes a first three-way valve 6, a solid heat storage tank 7, a liquid heat storage tank 8, and a second three-way valve 9. The solid heat storage tank 7 and the liquid heat storage tank 8 are connected in parallel between the first three-way valve 6 and the second three-way valve 9. The first three-way valve 6 is connected to the air outlet of the heater 5, and the second three-way valve 9 is connected to the air inlet of the radiator 10. The solid heat storage tank 7 contains a solid heat storage medium.

[0029] When the heater 5 is heating, the generated heat energy is transferred to the liquid heat storage medium or the solid heat storage medium along with the airflow, thereby realizing the storage of sensible heat energy; when the heater 5 stops heating, the heat energy of the liquid heat storage medium or the solid heat storage medium is released along with the airflow, thereby realizing the release of sensible heat energy.

[0030] This experimental system has the energy storage function of raising and lowering the temperature of materials, and measures the heat absorption and release characteristics of materials, clearly demonstrating the structural principle of the energy storage experiment. The experimental system adopts semi-automatic settings, adds manual valves and experimental operations, making the experimental process more participatory and collaborative, and has a beautiful appearance.

[0031] The first three-way valve 6 and the second three-way valve 9 can be manual valves or electromagnetic valves. When manual valves are used, the physical examination of manual operation and experimental operation can be increased, so that the experimental process has a sense of participation and collaboration, and the appearance is beautiful.

[0032] A muffler is provided on the pipe at the air outlet end of the radiator 10 to reduce noise.

[0033] A pressure transmitter, an electric regulating valve 3 and a flow meter are arranged on the pipeline between the fan 1 and the inter-tube heater 5 .

[0035] The electric control box 14 is provided with a number of switch buttons, and the power supply circuit inside the electric control box 14 can supply power to power-consuming components such as the fan 1, the heater 5, and the industrial control touch screen 13. The industrial control touch screen 13 is connected to a 16-channel thermal resistance acquisition module, and each temperature sensor is connected to the acquisition module and is used to collect temperature data.

[0036] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
