Embodiment 1

[0041] refer to figure 1 and figure 2 , an energy-saving roof structure provided in this embodiment is arranged on the top of a building body with an air-conditioning system, and the air-conditioning system includes an air conditioner 1, a heat exchanger 2, and a water collecting tank 3 for adjusting the temperature inside the building body 4 , the outdoor air enters the building main body 4 after heat exchange through the heat exchanger 2, and then is discharged from the building main body 4 through the heat exchange device of the heat exchanger 2, and the condensed water of the air conditioner 1 is discharged into the water collection tank 3;

[0042]The energy-saving roof structure includes a roof panel 5, a support frame 7, and a roof panel 8. The support frame 7 is arranged above the roof panel 5, and the roof panel 8 is laid above the support frame 7;

[0043] A partition board 9 is also arranged above the roof panel 5, and the space between the partition board 9 and t...

Embodiment 2

[0050] refer to Figure 2 to Figure 4 , on the basis of Embodiment 1, this embodiment also includes an eaves cover, which includes an upper cover 17, an outer cover 18, and an inner cover 19. One side of the upper cover 17 and the outer cover 18 are closed and connected, the other side of the upper cover plate 17 is provided with a protruding flange 20, the shape of the inner cover 19 matches the protrusion of the flange 20, and there is a gap between the flange 20 and the flange 20. A filter screen 22 is arranged in the gap, a water storage tank 23 is arranged in the middle of the inner cover 19, the folded edge 20 extends into the water storage tank 23 and does not contact the bottom of the water storage tank 23, and a drainage groove 24 is arranged on the outside of the water storage tank 23;

[0051] The eaves cover plate is arranged on the upper part of the ventilation duct 6, and forms an eaves cavity 25 with the upper surface of the ventilation duct 6. A ventilation fla...

Embodiment 3

[0058] refer to Figure 3 to Figure 5 , In this embodiment, on the basis of Embodiment 2, in the energy-saving roof structure, in order to improve the heat dissipation effect, the roof panels 8 are two, which are distributed in an "eight" shape, and the height of one roof panel 8 is slightly higher. On the other roof board 8, an upper ventilation opening is formed between the upper parts of the two roof boards, and a dust filter 29 is arranged at the upper ventilation opening. A window can also be provided on the outside of the dust filter 29 to adjust the amount of ventilation.

[0059] As a preferred embodiment, in order to have better ventilation effect, in the energy-saving roof structure, the height of the ventilation channel 6 is 15-20 cm.

[0060] As a preferred embodiment, in order to make full use of energy, the material of the roof panel 8 is BIPV, and for better heat preservation, the separator 9 is an EPS foam separator.

Abstract

The invention provides a relatively-closed energy-saving roof structure utilizing condensate water of an air conditioner system and a use method of the energy-saving roof structure. The condensate water generated by an air conditioner is sprayed in a roof cavity through a spraying system, then through waste gas which is treated by a heat exchanger and then discharged from the interior of a building main body, heat in the roof cavity is brought away, and thus the effect of roof temperature decreasing is achieved. The temperature and the humidity of the waste gas which is discharged from the interior of the building main body after being treated through the air conditioner are relatively stable, and the waste gas flows through the closed roof cavity, so that the influence of the external environment on the temperature decreasing effect of the energy-saving roof structure is small, and the temperature decreasing effect is stable. The condensate water of the air conditioner is adopted as awater source of the energy-saving roof structure, and thus the problem that the water consumption is large in watering temperature decreasing is also solved.

Description

technical field [0001] The invention relates to a roof structure, in particular to an energy-saving roof structure and a method of using the same. Background technique [0002] With the accelerating process of urbanization and the continuous improvement of people's requirements for living comfort, the share of building energy consumption in the total social energy consumption is also increasing. It has become the general trend to reduce building energy consumption and actively develop energy-saving buildings. [0003] Water storage roof is a kind of energy-saving building. It can achieve a better cooling effect in summer and can save energy. However, the water storage roof has higher requirements for roof waterproofing and load, and it is used as a water with a large heat storage coefficient. , It is also not conducive to roof heat dissipation at night in summer. If the water cooling mode of the roof is replaced by the water storage cooling mode of the roof, although the p...
