Embodiment 1

[0055] This embodiment provides a method for indoor cooling using roof rainfall. The method processes roof rainfall, including the following steps: using a rainwater collection unit to collect roof rainfall, and using the collected rainwater to perform multi-stage rainwater treatment through the rainwater treatment unit. After treatment, the treated rainwater is pumped to the roof, and the rainwater pumped to the roof is dispersed on the roof for indoor cooling.

Embodiment 2

[0057] Such as Figure 1 to Figure 10 As shown, this embodiment provides a device for indoor cooling using roof rainfall, including a rainwater collection unit 1, the rainwater collection unit 1 is connected to a rainwater treatment unit 2, and the rainwater treatment unit 2 is connected to a rainwater delivery unit 3; the rainwater collection unit 1 includes a rainwater collection pipe 1-1, the outlet of the rainwater collection pipe 1-1 is connected to the urban underground drainage network pipe 1-2; the rainwater treatment unit 2 includes a first-level rainwater treatment unit 2-1 and a second-level rainwater treatment unit 2-2 The first-level rainwater treatment unit 2-1 includes a cuboid groove-shaped overflow pool 4, and a partition wall 5 is processed inside the overflow pool 4, and the partition wall 5 divides the overflow pool 4 into a water inlet chamber 6 and an outlet chamber 7, The height of the partition wall 5 is lower than the height of the side wall of the ove...

Embodiment 3

[0063] In this embodiment, on the basis of Embodiment 2, a water inlet buffer plate 21 is installed in the side wall of the static sedimentation tank 11 where the water inlet pipe 12 of the static sedimentation tank is located, and the bottom plate of the water inlet buffer plate 21 is parallel to the bottom of the static sedimentation tank 11 , the height of the bottom plate of the water inlet buffer plate 21 is lower than the height of the static sedimentation tank inlet pipe 12, the length of the water inlet buffer plate 21 is equal to the width of the side wall where the static sedimentation tank water inlet pipe 12 is located, and the side plate of the water inlet buffer plate 21 is perpendicular to the static sedimentation tank. The water inlet pipe 12 of the settling tank is directly opposite to the water inlet pipe 12 of the static settling tank, and a plurality of water inlet holes 21-1 are opened on the side plate of the water inlet buffer plate 21, and enter the stati...

Abstract

The invention discloses a method and device for indoor temperature reduction through roofing rain. The method comprises the steps that the roofing rain is collected through a rainwater collecting unit, the collected rainwater is subjected to multistage rainwater treatment through a rainwater treatment unit, the treated rainwater is pumped to roofing, and the rainwater pumped to the roofing is dispersed on the roofing for indoor temperature reduction. The rainwater collecting unit of the device communicates with the rainwater treatment unit, and the rainwater treatment unit communicates with arainwater delivery unit; the rainwater collecting comprises a rainwater collecting pipeline; the rainwater treatment unit comprises a first-stage rainwater treatment unit body and a second-stage rainwater treatment unit body; and the rainwater delivery unit comprises a rainwater delivery pipe, a water inlet of the rainwater delivery pipe communicates with a water pressing pile, and a water outletof the rainwater delivery pipe communicates with a water leaking pipe. Aiming at the purpose of indoor temperature reduction of a large-space building, roofing rain is stored and utilized after rain spell, the roofing and indoor air are subjected to temperature reduction through rain evaporation, the technology is feasible, and the method is more economical than a traditional temperature reductionmethod.

Description

technical field [0001] The invention belongs to the field of rainwater utilization, and in particular relates to a method and a device for indoor cooling by utilizing roof rainfall. Background technique [0002] As water resources become more and more scarce, rainwater, as an additional water resource to be used, has been paid more and more attention to its treatment and utilization. The emergence and rise of the concept of sponge city corresponds to this concept. Its central idea is to enable the city to be like a "sponge", which has good "elasticity" in adapting to environmental changes and natural disasters, and absorbs water when it rains. , water storage, water seepage, water purification, and when needed, "release" the stored water and make use of it. At present, the specific implementation direction of the sponge city can be reflected in urban construction by using "green" measures such as grass planting ditches, seepage bricks, rain gardens, and sunken green spaces ...
