Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting structure for an air type solar heat collector disposed on a roof.

BACKGROUND ART Solar heat collectors have traditionally been installed on the south roof of a house for the purpose of supplying hot water and heating and cooling the house. Typical types of heat collectors are water-type heat collectors that use water as a medium and air-type heat collectors that use air as a medium.Of these, air-type heat collectors use air as a medium. As a result, there is no damage to the building due to water leakage, and since it is lightweight, there is no need to particularly strengthen the building structure to support the heat collector, so it has recently attracted attention.

When installing pneumatic heat collectors on a roof, it is common to arrange unitized heat collectors in series in the vertical direction of the slope of the roof. It is necessary to install a low-temperature side duct on the connecting pipe that interconnects the air circulation spaces and a heat collector located below the slope, and a high-temperature side duct on the heat collector located above the slope. Since the pipes and ducts are exposed on the roof, they not only spoil the aesthetic appearance of the building but also cause malfunctions.

Furthermore, since the medium air is sent to the heated air circulation space through the bent connecting pipe, air resistance is large.

Furthermore, since the heat collector is disposed directly on the roof, rainwater that hits the roof surface during rainfall is likely to bounce back into the heat collector and cause the heat collector to malfunction.

The present invention will be explained below with reference to the drawings.

In FIG. 1, waterproof paper (not shown) or the like is laid on a roof board or roof board 1 of a building to form a roof base. A pneumatic solar heat collector (hereinafter referred to as a heat collector) described below is installed on the roof base, but the rest of the roof is covered with roofing materials such as slate, metal plates, tiles, etc.

In the above-mentioned roof base material surface, a heat collector support frame 3 rising upward is installed on the roof base ground approximately corresponding to the installation base area of the heat collector 2 to be installed.
The support frame 3 is made by laying two wooden square timbers or metal shapes on the left and right sides along the slope of the roof on the roof board 1, and further arranging similar square timbers at the upper and lower ends to form a square frame-shaped support frame 3. , fix to the roof board 1 or to the rafters 4 (Fig. 2) through the roof board. Apply rain protection to the heat collector support frame 3 as appropriate. Note that when the heat collectors 2 are arranged in series, the support frame 3 supports a group of heat collectors arranged in series.

As shown in FIGS. 2 to 4, each heat collector 2 is formed into a rectangular frame having a transparent plate 5 on the upper surface, a bottom plate 6 on the lower surface, and side plates 7 on all four sides. The internal space between the transparent plate 5 and the bottom plate 6 is covered with a transparent plastic sheet 8.
The heated air circulation space 1 is divided vertically into two spaces: a heat insulation space 9 and a heated air circulation space 10.
A corrugated heat collecting plate 11 having a heat collecting surface formed by painting black or the like on the surface is built into the inside of the heat collecting plate 1. A horizontal plate 12 that overlaps the edges of the transparent plastic sheet 8 and the heat collecting plate 11 and extends from the side plate 7 into the internal space.
Place it on top and fix it with screws etc. In this case, the heated air circulation space 10 extends in the vertical direction of the slope of the roof.

The opposing side plates 7 of the heat collectors 2 formed in this way and arranged in series and adjacent to each other in the inclination direction include:
An opening 13 is formed that communicates the heated air circulation space 10 with each other. The four heat collectors 2 around the opening 13 are sealed airtightly and watertightly with a tight material T, and the upper part between the adjacent heat collectors is covered with a transparent plate presser 14 with fingers.

With the above configuration, a linear sealed continuous space extending in the vertical direction of the slope is created through the plurality of heat collectors, so there is an advantage that air resistance is reduced when heated air flows.

As shown in FIG. 2, a low temperature side duct 16 and a high temperature side duct 17 are installed in the attic 15 (the space between the roof and the ceiling). Low temperature side duct 16
is formed near the eaves of the roof, and the high temperature side duct 17 is formed near the ridge. An air inlet 18 and an air outlet 19 are perforated in the shedding board 1 facing the ducts 16 and 17, respectively. In addition, the heat collector plate 6 located at the lowest position in the direction of inclination is provided with an air introduction opening 20, and the heat collector bottom plate 6 located at the highest position in the direction of inclination is provided with an air discharge opening 21.
A communication flow path 22 extending from the low temperature side duct 16 to the intake port 18 to the introduction opening 20 and a communication flow path extending from the high temperature side duct 17 to the output port 19 to the discharge opening 21 are formed in the internal space of the heat collector support frame 3. 23.

By forming it in this way, an air flow path can be easily formed even in an overhanging place such as an eave, and since the main part within the support frame 3 is provided with the heat insulating material 24, it is effective for heat retention, and also There is an advantage that the heating device 2 can be made smaller.

According to the present invention, the heated air flow path between the heat collectors is sealed airtightly and watertightly with a tight material, and the upper part of the flow path is further protected by a transparent plate retainer. Not only is it completely airtight and watertight, but the outer surface of the tight material is not exposed to wind and rain, so it is extremely durable. Piping such as connecting pipes and ducts can be installed in the attic, which not only improves the appearance of the building, but also improves the durability of the piping because it is not damaged by heat, ultraviolet rays, freezing cold air, etc. Furthermore, since the heat collector is installed at a position one step higher than the roof surface, rainwater does not enter the heat collector.
