Example 3

1 to 7 , a third embodiment of the present invention is shown, which is different from the first two embodiments: this embodiment provides a heat storage peak-shaving cycle device.

Specifically, the circulation component 300 includes a box body 301, a support leg 302 fixedly arranged at the bottom of the box body 301, and four support legs 302 are arranged.
