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

Embodiment 2

[0050] refer to Figure 2 to Figure 4 , on the basis of Embodiment 1, the present embodiment also includes an eave cover plate, and the eave cover plate includes an upper cover plate 17, an outer cover plate 18, an inner cover plate 19, one side of the upper cover plate 17 and an outer cover plate 18 are closed and connected, the other side of the upper cover 17 is provided with a raised 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, Filter screen 22 is set in the gap, and water storage tank 23 is set in the middle part of inner cover plate 19, and described flange 20 stretches into water storage tank 23 and does not contact with the bottom of water storage tank 23, and the outside of water storage tank 23 is provided with drainage tank 24;

[0051] The eaves cover plate is arranged on the top of the air passage 6, and forms the eaves cavity 25 with the upper surface of the air passage 6, and a vent...

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 pieces, which are distributed in a "eight" shape, and the height of one roof panel 8 is slightly higher On another roof board 8, an upper vent is formed between the tops of the two roof boards, and a dust filter 29 is arranged at the upper vent. Windows can also be set on the outside of the dust filter net 29 to adjust the size of the ventilation.

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

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 its application method. Background technique [0002] With the acceleration of urbanization and the continuous improvement of people's requirements for living comfort, the share of building energy consumption in the whole society's energy consumption is also increasing. It is the general trend to reduce building energy consumption and actively develop energy-saving buildings. [0003] The water storage roof is a kind of energy-saving building. It can achieve a better cooling effect in summer and can save energy. , It is also not conducive to roof heat dissipation at night in summer. However, if the mode of sprinkling and cooling is used instead of the mode of water storage and cooling on the roof, although it can solve the problem of high waterproof requirements of the roof load, but the water consumption and cooling of the sprinkler also have water consum...
