Abstract

PURPOSE:To improve heat collection performance by a structure wherein an absorbing plate with simple construction and high heat absorption factor is arranged in a sun room. CONSTITUTION:When rays of the sun fall through a lighting window 13 mounted on a roof 11 into a sun room 12, heat rays are absorbed by an absorbing plate 18 and consequently the air in the sun room 12 is heated and ascends in a form of warm air and is led through a warm air extracting port 16 in a duct and then fed to a sitting room for heating and, after that, ascends through an intake port 17 in the sun room 12 in order to be heated again. The absorbing plate 18 consists of a plate, which is corrugated for enlarging heat transfer area and coated its surface with black paint for heightening the absorption factor to heat rays and furthermore perforated with a large number of vent holes 20, 20,...20 for prompting the convection of the warm air in the sun room 12 in order to improve the heat collection performance.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a solar heating system, and more particularly to a solar heating system in which a simple heat collecting plate is installed in an attic space to improve heat collecting performance.

[Technical background and problems of the invention]

2. Description of the Related Art A solar heating device as shown in FIG. 1 is known as a device for heating a room in a house by utilizing the thermal energy of sunlight. This is a sunroom 2 on the back side of the roof l.
The sunlight is guided into the sunroom 2 through the daylight window 3 to increase the temperature inside the sunroom 2, and the warm air inside the sunroom 2 is passed through the duct 4 into the downstairs living room 5. guided by. A blower @6 is installed on the duct 4 to forcefully circulate warm air, and a communication path 7 is formed at the boundary between the sunroom 2 and the living room 5.

However, this conventional heating system that utilizes solar heat cannot sufficiently raise the temperature of the living room 5 because the heat transfer area to the air is insufficient for the amount of sunlight that enters through the daylight window 8. There was a problem that the heating effect was insufficient.

[Purpose of the invention]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a solar heating system in which a heat collecting plate with a simple structure is installed under the pressure inside a sunroom to enhance the heat collecting action and improve the heating performance compared to the conventional method.

[Summary of the invention]

In order to achieve the above object, the present invention introduces sunlight into the sunroom in the attic through a daylight window installed in the roof, heats the indoor air to generate warm air, and then passes this warm air through a duct to heat the room. In a solar heating system designed to lead indoors, the heat collecting performance is improved by arranging a heat collecting plate with a high heat absorption rate in the sunroom.

[Embodiments of the invention]

An embodiment of the solar heating device according to the present invention will be described below with reference to FIGS. 2 to 5.

In FIG. 2, a sunroom 12 is formed on the back side of a roof 11, and a lighting window 13 is attached to a part of the roof 1. The roof 11 has an inclination of about 30 degrees with respect to the horizontal plane, and the sunroom 12 is surrounded by a ceiling wall 14 and a vertical wall 15, forming a room having a triangular cross section. Heat leakage can be effectively prevented by constructing the ceiling Ji 14 and the vertical wall 5 using appropriate heat insulating materials. Further, above the sunroom 12, a warm air outlet 16 is provided in the vertical wallwork 5, and a ceiling wall 14 is provided.
is provided with an intake port 17 for taking in air from the living room. This intake port 17 is preferably provided with a grill in the form of louver wings so that the opening area can be adjusted.

Note that, similar to the conventional example shown in FIG. 1, the hot air intake port 16 is equipped with a duct 4 and a blower 6 that communicate with the living room, so that warm air can be forced into the living room 5. Of course, it has become like this.

According to the present invention, a heat collecting plate 18 is disposed inside the sunroom 12, and this heat collecting plate 18 is arranged parallel to the daylighting window 13 in FIG. Retained. This heat collecting plate 18 is.

The surface is coated with black paint to increase the absorption rate of heat rays, and although it may be constructed from a flat plate, it is effective to use a corrugated plate to increase the heat transfer area. The heat collecting plate 18 shown in FIG. 3 uses a corrugated plate, and in order to improve the convection of warm air inside the sunroom 12, the heat collecting plate 18 has a large number of ventilation holes 20120. ...
, 20 are perforated.

Furthermore, in the embodiment shown in FIG.
are arranged parallel to the ceiling wall 14.

FIG. 5 shows a modified example of the heat collection plate 18 with dowels. . . 21 are arranged side by side in a panel shape.

According to the embodiment of the present invention configured in this manner, when sunlight enters the sunroom 12 through the daylight window 13, the sunlight is irradiated onto the heat collecting plate 18, and the heat collecting plate 18 absorbs the heat rays. The heat is conducted to the air inside the sunroom 12, and the indoor air is heated and becomes warm air. This warm air rises due to the convection phenomenon, is led into the duct through the hot air intake port 16, is sent to the living room by the blower, heats the living room, and then rises.

It is sent into the Sinan room 12 through the intake port 17 and heated again.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, since a heat collection plate with a large heat transfer area is provided in the sunroom, the heat collection performance of sunlight incident through the daylight window can be improved. Even if the volume of the sunroom is small, the amount of heating heat can be easily secured, and the heating effect can be achieved by saving energy.
