Embodiment 1

[0033] This embodiment provides a cooling system for building exterior walls, such as Figure 1 to Figure 4 As shown, it includes a rainwater storage device, a sprinkler net 1 and a plurality of sprinkler heads 2. The rainwater storage device communicates with the sprinkler heads 2 through a water pump 9. The sprinkler net 1 is arranged on the surface of the building exterior wall 3, and the rainwater flows from the sprinkler The shower head 2 sprays out and drenches on the water shower net to form a water film.

[0034] When it rains, the rainwater storage device collects and stores the rainwater. When the weather temperature is high, the rainwater in the rainwater storage device flows to the sprinkler head 2 on the surface of the building exterior wall 3 under the drive of the water pump 9, and further Spraying on the water shower net 1, since the temperature of the rainwater on the water shower net 1 is relatively low, the temperature of the outer wall 3 of the building can...

Embodiment 2

[0051] This embodiment provides a cooling method for building exterior walls, comprising the following steps: obtaining the temperature of rainwater in the heat preservation water tank of the rainwater storage device and the surface temperature of the exterior walls of buildings; when the difference between the surface temperature and the temperature of rainwater exceeds a threshold , Turn on the water pump, and the rainwater in the heat preservation water tank is sprayed on the water net through the sprinkler head, and exchanges heat with the outer wall of the building to complete the cooling of the outer wall of the building.

[0052] Compared with the prior art, the beneficial effects of the cooling method for building exterior walls provided in this embodiment are basically the same as those of the building exterior wall cooling system provided in Embodiment 1, and will not be repeated here.

[0053] Specifically, the above-mentioned cooling system includes a monitor, a wat...

Abstract

The invention discloses a cooling system and a cooling method of an external wall of a building, belonging to the technical field of temperature regulation of a building outer protective structure, which solves the problem that the cooling amount of rainwater in the prior art is not effectively utilized. A system for cool that exterior wall of a building comprises a rainwater collect and storing device, a water spraying network and a plurality of shower head, wherein the rainwater collecting and storing device is communicated with the shower head through a pump, a water spraying network is arranged on the surface of the exterior wall of the building, and rainwater is sprayed from the shower head to form a water film on the water spraying network. The cooling method comprises the followingsteps of: acquiring the temperature of the rainwater in the heat preservation water tank of the rainwater collecting and storing device and the surface temperature of the external wall of the building; When the difference between the surface temperature and the rainwater temperature exceeds the threshold value, the water pump is turned on, and the rainwater in the heat preservation water tank is sprayed on the sprinkler net through the sprinkler head, and heat exchange is carried out with the external wall of the building, so as to complete the cooling of the external wall of the building.

Description

technical field [0001] The invention relates to a temperature regulation technology of a building outer protection structure, in particular to a cooling system and a cooling method for a building outer wall. Background technique [0002] At present, the main ways of cooling the building envelope are ways to reduce heat gain (such as heat insulation, sunshade, building greening, etc.) and ways to increase heat dissipation (such as middle layer ventilation, cold radiation coating, etc.). Among them, the method of reducing heat gain has been widely used in various buildings, but the method of increasing heat dissipation has problems such as high cost, complicated operation and maintenance, and the use effect needs to be improved. [0003] Rainwater is a good quality natural cold and heat source, inexhaustible and inexhaustible. Existing rainwater collection and utilization are only for rainwater sewage discharge and other functions, but have not been applied to the cooling fie...
