Embodiment 1
[0018] Embodiment 1: see Figure 1-Figure 2 , using a linear Fresnel reflective solar heat collection device combined with a sun room, including a double-slope roof sun room 1, a linear Fresnel reflector 2, a secondary reflector 3, a straight-through vacuum heat collector 4, a fixed hanging Frame 5; linear Fresnel reflection device 2, secondary reflection device 3, straight-through vacuum heat collector 4, and fixed hanger 5 are located inside the double-slope sun room 1, and the roof of the double-slope sun room 1 faces south and Tilting to the north, the secondary reflection device 3 and the straight-through vacuum heat collection tube 4 are fixed on the double-slope roof sun room 1 through the fixed hanger 5, the secondary reflection device 3 is located above the straight-through vacuum heat collection tube 4, and the linear Fresnel The reflection device 2 is located on the ground inside the sun room 1 with a double-slope roof.
Embodiment 2
[0019] Example 2: see Figure 1-Figure 2 , as an improvement of the present invention, the double-slope roof sun room 1 includes a door 6, a sun room frame 7 and lighting glass 8; the door 6 is located on the east and west sides of the double-slope roof sun room 1, and the sun room frame 7 is Metal frame, lighting glass 8 is fixed on the sun room frame 7. The rest of the structures and advantages are exactly the same as in Embodiment 1.
Embodiment 3
[0020] Embodiment 3: see Figure 1-Figure 2 , as an improvement of the present invention, the inclination angle of the south-facing slope of the double-slope roof sun room 1 is 5-35 degrees, and the inclination angle of the north-facing slope of the double-slope roof sun room 1 is 30-70 degrees. The rest of the structures and advantages are exactly the same as in Embodiment 1.
