Embodiment Construction

[0069] figure 1 It is a longitudinal sectional view of the first embodiment of the air-type solar heat collection and ventilation system. Figure 10, also as figure 2 , 3 As shown, it is a very thin ventilation layer 13 with a distance between the solar radiation light receiving plate 11 and the backlight plate heat absorbing plate 12 of about 15mm or less (for example 8mm), and a flat plate shaped body installed in parallel. The plate-shaped body 10 may also have a curved shape. and, if Figure 7 The light receiving plate 11 shown can also have a concave-convex corrugated plate, so as to increase the light receiving area.

[0070] The ultra-thin ventilation layer 13, due to the thinning of the ventilation layer, improves the contact efficiency between the light-receiving plate and the air flowing through the ventilation layer, and improves the heat exchange performance. Its thickness is about 15mm or less, and the preferred thickness is about 8mm. (However, if the handl...

Abstract

The present invention discloses an air-type solar heat-collecting ventilation system. An extremely thin venting layer is formed between the solar radiation lighted side plate and the shaded side plate, and the thickness of the extremely thin venting layer is less than 15 mm, the length is ranged from several centre meters to several meters and the section inner flow rate is less than 5m / s, one end of the venting layer is air inlet and another end is air blowing mouth, the plate bodies of the end mouth surface formed by facing solar lighted side and shaded side are fully arranged and installedon the solar radiation lighted surface as air-type heat-collecting materials, the air blowing out mouth faces the collecting venting layer formed by the solar radiation lighted side and shaded side of plate bodies, at the same time the continuous space of plate bodies used for venting and connected with said air inlet is formed. The invention can provide adequate indoor ventilation to prevent chemical pollution, condensation and moldy and insects, on the other hand, the use of solar energy to release the cold venting air temperature in cold seasons, it plays an active role of preventing global greenhouse phenomenon and the problem of inadequate energy.

Description

technical field [0001] The present invention relates to the installation on the walls, roofs, sunshades, balcony handrails and other parts of buildings, and is mainly aimed at the air-type solar heat collection and ventilation system for spaces that need ventilation and heating. Background technique [0002] The thermal performance of Japanese buildings is very lacking from an energy saving point of view. The heat of summer is spent by electric air conditioners, and the cold of winter is heated by burning oil in large quantities. As a result, houses and buildings have a huge negative impact on the global warming phenomenon caused by energy crisis and carbon dioxide. [0003] In terms of building heat loss, if Figure 27 The building area shown is about 120m 2 For residential buildings, the new energy-saving standard is 339kacl / ℃ (0.39kW / ℃) in the heat loss expected from roof (8%), exterior wall (27%), floor (14%), window (44%), door (2%) ), proportional loss of ventilation...
