[0033] In some embodiments, a water mist nozzle 5 is pre-buried in the vegetation turf 20 to further enhance the cooling effect.

[0034] like Figure 3 As shown, there are multiple water mist nozzles 5 on the spray section, and the multiple water mist nozzles 5 are arranged at intervals along the length direction of the spray section.

[0035] like Figures 4-8 As shown, the photovoltaic system includes an adjustable support frame and a photovoltaic panel 21 laid on the upper end of the adjustable support frame; the adjustable support frame is installed on the roof.

[0036] The adjustable support frame includes a universal shaft 11, a movable keel 22, a fixed keel 23, and a height adjustment member; the movable keel 22 is connected to the photovoltaic panel 21, and the movable keel 22 is disposed above the fixed keel 23, and a plurality of height adjustment members are supported between the fixed keel 23 and the movable keel 22; the flow guide plate 7 and the spray section are disposed between the fixed keel 23 and the movable keel 22.
