Abstract

PURPOSE:To increase the effect of heat collection by a method wherein air in a heat collecting chamber is taken in from below to enable it to circulate upward and the air and heat are flowed in the same direction by regular convection. CONSTITUTION:The heat collecting chamber 4 serving as a window is provided in the side wall 1 of a building subject to the sunlight, a blind 10 serving as a heat collecting member is provided at the lower part of the indoor side wall of the chamber 4. Further, a hot air inlet hole 12 is drilled in the upper wall of the chamber 4 and the inlet hole 12 and a heat collecting header 14 of the chamber 4 are made to communicate with each other through a vertical air introducing pipe 13. Further, a plurality of air introducing pipes 15 laid under the floor are attached to the heat collecting header with the other ends connected to an air intake fan through an air collecting header. In other words, the air and heat in the heat collecting chamber flow in the same direction by regular convection and as a result, the use of the heat within the heat collecting chamber is made sufficiently since the air and the heat flow in the same direction by regular convection and the air heated efficiently is flowed into a floor heating section under the floor as it is so that when solar heat is utilized, no heat loss arises and a desired room heating operation is attained.

Description

Detailed Description of the Invention The present invention mainly uses solar heat to heat a house, and when circulating air warmed by solar heat, This invention relates to a heating device using solar heat using direct convection, in which both flows are made to flow in the same direction instead of in a reverse flow relationship, thereby creating a heat collecting effect.

Conventionally, in order to heat a building using solar heat, as shown in Figure 6, a blind (10) to collect heat was installed inside the wall that was exposed to sunlight, and it also served as a window. A heat collection chamber (4) is installed, and the indoor air flows into the room (4) through the intake hole (11') provided above, and the air is directed downward from above the heat collection chamber (4). During this period, solar heat is absorbed, which is then flowed from the heat collection header section (14) below to the air guide pipe (15) piped under the floor to perform floor heating, and this still warm air is heated by an intake fan. The air is pumped into the room, and this flow is circulated to heat the room.

In this case, the temperature in a room with floor heating is that there is not much difference in temperature between the floor and the ceiling, and the difference is about 10, so the air sent into the room by the intake fan is It is natural to introduce the heat into the heat collecting chamber (4) through the suction hole (11').

In addition, in the heat collection room (4), the heated air tends to rise, but this air is allowed to flow slowly from the top to the bottom in the heat collection room (4), and this has a sufficient heat collection effect. Over the years, solar heat has always been used in the heat collection chamber (4) by forcing it to flow backwards from the top to the bottom.

These were considered to be reasonable.

However, in reality, the heat collection effect is extremely poor.
As a result, the temperature in the room did not rise to the expected temperature as calculated.

This was found to be based on the following reason.

That is, at the pressure inside the heat collection chamber, the air flows from the top to the bottom as described above. However, it is natural for warm air to flow upward rather than downward, so the flow of heat will flow upward rather than downward.

In other words, the flow of air and the flow of heat are opposite, creating a countercurrent flow, so air flows downwards from above, but heat stagnates upwards, and this heat heats unnecessary parts of the building or is absorbed by outside air. wastefully dissipated.

If the flow of air and the flow of heat are made to match and form a direct convection, it is possible to fully utilize solar heat without heat loss.

The present invention has been developed based on this theory, and its effectiveness has been confirmed through experiments.

This will be explained based on what is shown in the figure.

0) is formed. (4) is a solar heat collection room that also serves as a window, and (5) is a balcony.

Heat collection chamber (4) #i, Figure 2 and! As shown in Figure 3,
Blinds (lO) are installed above and below the interior.

The blind (10) has a black color on the negative side, which is used to collect heat in the winter, and a white color on the other side.

This reflects solar radiation during stormy periods.

As shown in FIG.
0'') is moved up and down, and in the winter it is superimposed on the back side of the black blind (10'), and in the summer it is superimposed on the surface of the black blind (10').
It is convenient to use 10).

An air intake hole (11) is provided at the lower part of the indoor side of the heat collection chamber (4), and the air inside the room (B) and the like flows into the heat collection chamber (4) through the air intake hole (11).

A vent hole (xa) (1g) for hot air heated in the heat collection chamber (4) is bored in the upper wall of the left and right sides of the heat collection chamber (4).
) A vertical air guide pipe (13) (13) communicating with the same outlet hole (x2) (1g) is provided on the outside of the heat collection chamber (
4) Open in the lower heat collecting header part (14).

(15) is an air guide pipe that guides the warm air collected in the heat collecting header part (14) to the underfloor, and these air guide pipes (xa), (la)...
・A floor heating section is formed, and the warm air flowing therein performs floor heating and is then blown into the room by an intake fan (1) from an air collection header (16).

The effect will be explained.

The air in the chamber (B) flows through the intake hole (11) into the heat collection chamber (
It enters the lower part of the room (4), is heated by solar heat in the same room (4), and at the same time is heated by the heat collected by the blind (10), and flows upward. This hot air flows through the upper left and right outlet holes (12
) (12), the vertical air guide pipe (13) (13) descends, passes through the heat collecting header part (14), and then the air guide pipe (lδ) (15)...
The air flows through the air, performs floor heating, and is discharged into the room (B) by the intake fan (l-1) from the air collection header (16), and the still warm air is used to heat the room (B). Warm up inside.

When the weather is sunny, the room is heated to about 2,001 degrees Fahrenheit, and at night, the accumulated residual heat from the floor (1B) heats the room to about 1'F''olc.

According to the present invention, indoor air is taken in from below in the heat collection room and is flowed upward, and the flow of air and the flow of heat are made into a direct convection flow in one giant direction. In addition, this efficiently heated warm air is flowed to the floor heating section under the 11th floor for floor heating, making it possible to utilize solar heat. This makes it possible to heat the room at the desired temperature without heat loss.

According to experiments, in the conventional type with reverse flow shown in the tiK5 diagram, the temperature above the heat collection chamber was approximately 20"O1.

In contrast, in the case of the present invention, the temperature near the intake hole of the heat collection chamber is about ao@o, and the temperature near the upper outlet hole of the heat collection chamber is about 5.
00, the temperature of the lower heat collecting header section is approximately 45'''C, which roughly speaking means that it is possible to utilize hot air that is nearly 000 g higher than before. Considering that it can be used throughout the day, the effect is significant.
