Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to solar heat utilization, and particularly to a curtain wall for solar heat collection in which a heat collector is incorporated into the outer wall of a building.

In Japan, there has been a crisis in oil energy since the oil crisis, and in recent years many oil energy conservation methods have been proposed, particularly through the Sunshine Project, which utilizes solar heat.

The most common of these is the Sofu House, which is also called a solar heated house and heats and supplies hot water to the house, but these have a heat collector installed on the roof of the house at an angle to take sunlight into consideration. . This not only impairs the aesthetic appearance of the building, but also has disadvantages such as increased construction costs due to the conventional double roof structure consisting of the roof and the heat collector. Furthermore, there has been a concept of using solar heat collectors in the curtain walls of buildings to concentrate solar heat.

However, the mounting structure, piping method, and piping installation method of the solar heat collector have not been sufficiently elucidated, and it is actually difficult to incorporate the solar heat collector into the curtain wall. The present invention provides a curtain wall structure for a solar heat collector having a piping structure in which the above concept can be practically applied to the curtain wall.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
In Figures A and IB, on the outer surface of a building 100, spandrels 101 and lighting windows 102 using transparent plates are arranged alternately on each floor through mullions 6 by means of a flat floor slab S. It is provided. In the spandrel section 101, a large number of panel-shaped heat collector units 1 each consisting of a transparent plate 3 such as a glass plate and a heat collecting plate 4 of a known type that collects solar heat into a fluid medium are arranged in parallel in the same number on each floor. do. 2 indicates a heat insulating material.

Reference numeral 5 denotes a well-known type of cage heating tank, which includes a high-temperature side soot storage tank 5a and a low-temperature side medium storage tank 5b.

A fluid medium such as water, for example, is fed from the low temperature side medium storage tank 5b by a pump P through a conduit to an upright feed pipe A provided in a space at a vertical edge of the strength wall of the building 100. The fluid medium is pushed upward in the vertical feed pipe A, and at the same time, the horizontal feed pipe P provided in each spandrel section
, P... The horizontal feed pipe P is provided in the space behind the heat collector unit 1, extending well over the heat collector unit groups on each floor, and connects the horizontal feed pipe P and each heat collector unit to supply a fluid medium. Branch feed. The fluid medium absorbed and heated by solar heat by each collector unit flows out into the horizontal delivery pipe Q arranged in the same space as the horizontal delivery pipe, and flows into the horizontal delivery pipe Q arranged in the same space as the horizontal delivery pipe. It collects in delivery pipe B and rises.

Furthermore, the heating fluid medium from the heat collector unit groups on each floor is collected by the prefectural delivery pipe B, and enters the high-temperature side soot storage tank 5a of the heat storage tank 5 via another vertical delivery pipe B2, and is transferred to the high temperature side soot storage tank 5a of the heat storage tank 5. Used for heating and hot water supply. Also, the low temperature side fluid medium in the low temperature side medium storage tank 5b is sent by the pump P, and the circulation is repeated. The heat storage tank 5 is provided close to the upright pipes B and B2 as shown in FIG. and the lower end of the vertical feed pipe A. In FIGS. 2 and 3, 6 is a mullion face material groove 6a,
6a is a mullion that holds the heat collector unit 1.

Incidentally, in the lighting window section 102, a surface material (not shown), for example, glass, which forms a window entrance in the Omenmura grooves 6a, 6a, is iron-clad, as in a normal curtain wall. A bracket 8 with an L-shaped cross section is attached to the back of the mullion 6, and a partially annular pipe stopper 9 is fixed thereto, and the horizontal feed pipe P and the horizontal delivery pipe Q are maintained with similar metal fittings 9, 9, respectively. Further, the fluid soot body intake port 10 and the fluid soot intake port 11 on the back side of the heat collector unit are connected to the respective horizontal pipes by a connecting pipe 12. 13 is a heat insulating material for a fluid medium.

In FIG. 2, the horizontal feed pipe P is positioned lower than the horizontal feed pipe Q. FIG. 4 shows an upright feed pipe A, which is provided in a vertical edge space of the building surrounded by a corner cover 14 and feeds a horizontal feed pipe P with a fluid medium.

In the above embodiment, a curtain wall having a daylight window section and a spandrel section has been described, but the outer wall of the building may be a windowless curtain wall.

Further, although the heat insulating material 2 is incorporated into the heat collector unit, it may be attached separately. As shown in FIG. 5, both the horizontal pipes P and Q are arranged so as to have an upward slope in the direction of movement of the medium, that is, toward the downstream.

With this configuration, the medium can be extracted from the upstream side, that is, from below, at night when the heat collecting device is not in use.
According to the first aspect of the present invention, a number of solar heat collection units are installed on each floor, and piping is arranged in parallel to the L heat collector units on each floor, and the heat collector units on each floor are arranged vertically. They should be arranged in parallel (the horizontal feed pipe P and the horizontal feed pipe Q, which are directly connected to the heat collector unit group, are branched from the vertical feed pipe A and the prefectural feed pipe), and the vertical feed pipe B returns from the upper end. Since another upright delivery pipe B2 is connected to the heat storage tank 5, the liquid volume of the medium flowing into each heat collector unit is equal, and when installing a solar heat collector on a curtain wall, multiple solar heat collectors can be used. Units can be placed.

In addition, since the heat collector units are not arranged in series in the vertical direction of the curtain wall, the resistance of the medium liquid does not become excessive due to the heat collector units, and since there is no vertical piping, it does not interfere with the formation of windows in the building. . According to the second aspect of the present invention, when the heat collector units on each level are arranged in parallel, and when the heat collector units on each level are arranged vertically in parallel, the vertical feed piping is Thermal efficiency is improved by connecting the pipes connecting A and the heat storage tank 5 and between the prefectural delivery pipe B and the external heat tank 5 using the horizontal pipe C on the outgoing side.

That is, since the medium temperature on the forward side is lower than the medium temperature on the return side, there is less heat loss and therefore thermal efficiency is improved. Furthermore, according to the embodiment of the present invention, since the heat collector unit is attached using the mullioned iron grooves in the face material, there is no need for fasteners to be attached to the heat collector unit itself to the lotus frame. All you need to do is consider the thickness and size of the attached spandrel panels, etc. of the aircraft.

In addition, even if breaks between floors (breaks in the slab between each floor) occur due to an earthquake, etc., the gaps between the mullions prevent unexpected external forces from being applied to the heat sink unit, increasing the strength of the heat collector unit. At least you don't have to worry about damage. In addition, piping can be easily done by simply shifting the fasteners that fix the mullions to the floor slab from the upper and lower positions of the heat collector unit, and the construction can be carried out in the same way as the subordinate curtain wall. Furthermore, by using the spandrel parts, which were previously only used for decoration, it is possible to incorporate a nest heater while maintaining the aesthetic appearance of the building, and by arranging nest heater units of the same product in parallel, thermal efficiency can be improved. This has the advantage of reducing construction costs.
