Embodiment 1

[0058] Preparation of radiatively cooled building skins:

[0059] (1) Take a commercially available color steel tile, spray a weak acid cleaner (sulfamic acid solution, pH 4.5) on the outer surface of the color steel tile, let it stand for 5 minutes to 30 minutes after spraying, and then use a floor brush to clean the surface of the color steel tile. Wipe it, and then rinse it with a high-pressure water gun until there is no colored rust on the surface of the color steel tile and there is no scratching feeling when touched by hand;

[0060] (2) After drying the surface of the color steel tile, evenly spray commercially available quick-drying self-spray paint on the surface of the color steel tile. The average thickness of the coating is 0.2mm, and the coating is obtained after curing for 1 minute;

[0061] (3) Provide a radiation cooling film including a radiation cooling layer and a metal reflection layer. The side of the radiation cooling film close to the metal reflection l...

Abstract

The invention discloses a construction method of a radiation refrigeration film in an outer layer of a building and a radiation refrigeration outer layer. The construction method of the radiation refrigeration film in the outer layer of the building comprises the following steps: S1, cleaning the surface of the outer layer of the building by using a weak acid cleaning agent; S2, drying the cleanedouter layer of the building, coating a 0.2-2 mm thick coating to the surface of the outer layer of the building, and drying the coating to form a coating; and S3, providing the radiation refrigeration film, wherein a mount glue layer and a release protecting film are successively arranged from inside to outside on one side of the radiation refrigeration film, and after the release protecting filmis peeled off, the radiation refrigeration film is adhered to the coating through the mount glue layer.

Description

technical field [0001] The invention relates to the application of radiation cooling films, in particular to the construction method of the radiation cooling films on the outer layer of buildings and the outer layer of radiation cooling. Background technique [0002] With the rapid development of social economy, the energy crisis has become increasingly serious. According to relevant statistics, my country's building energy consumption accounts for about 30% of the total energy consumption of the society. With the growth of total construction and the improvement of living comfort, building energy conservation has attracted the attention of various countries and put into action. Air-conditioning energy consumption is one of the main building energy consumption, and a large amount of electric energy is consumed in the cooling process. Therefore, how to reduce air-conditioning energy consumption has become a research direction. [0003] As a new type of refrigeration method w...
