Further, as shown in FIG. 5, the partition wall Wa is formed by providing partition walls 60 similar to the inner wall 30 on the left and right of the column 5 made of H steel erected in the middle of the floor F. Have been. At a portion corresponding to the lower end of the partition wall portion 60, a groove 61 communicating with the groove 34 is formed.
The space between the partition walls 60 is formed as an air passage, and the upper end and the side end thereof are communicated with the outer air passage Aa so that the air in the outer air passage Aa flows. Further, a space formed between the pair of projection boards 36 of the partition wall portion 60 is configured as an air passage, the lower end portion of which is communicated with the groove 61, and the side end portion and the upper end portion are connected to the inner wall portion 30 and the inner side. The air in the inner air passage Ab is circulated by communicating with the air passage Ab2 of the roof portion 40.

Therefore, according to the warehouse H according to this embodiment, when the outside air temperature is low, for example, when the temperature is 2 ° C. or less, the opening / closing drive unit 54 of the air inlet 16 and the air outlet 26 is not opened. Since the open / close fins 53 are fully closed, no air is introduced or exhausted from the air inlet 16 and the air outlet 26. Therefore, the situation where snow blows into the outside air passage Aa or cold air enters can be prevented. Then, the transmission of cold air is suppressed by the air layers in the outer air passage Aa and the inner air passage Ab, so that the temperature of the storage space S can be kept without being lowered so much.
A situation that adversely affects the contents is prevented. In particular, because of the double structure of the outer air passage Aa and the inner air passage Ab, cold air is more difficult to be transmitted, and the heat of the accommodation space S is reliably maintained.

Next, when the outside air temperature rises, for example, the above-mentioned 2 ° C.
The opening / closing drive unit 54 of the air inlet 16 and the air outlet 26 gradually opens the opening / closing fin 53,
For example, when the temperature exceeds 10 ° C., the opening / closing fins 53 are fully opened. Therefore, the air rises in the outer air passage Aa, and fresh air is introduced from the air inlet 16 and exhausted from the air outlet 26. In this case, since the ventilation is always performed, the outer wall 1
Even if the outer roof portion 20 is heated, the heat is transmitted to the air flowing through the outer air passage Aa, and therefore, the rise in the temperature of the storage space S is suppressed. In particular, when the outside air temperature is high such as in summer, it is extremely effective. In addition, the above 2 ° C
In the range from to 10 ° C., the opening / closing fins 53 are gradually opened according to the temperature rise, so that the amount of introduced air can be adjusted, so that appropriate heat exchange can be performed.

Further, in the inside air passage Ab, the temperature of the floor F is lower than that of the inner wall 30 and the inner roof 40 due to a rise in temperature, so that air circulates due to this temperature difference. In this circulation process, the flowing air is cooled by the concrete floor F, so that the temperature rise is suppressed. Therefore, this also suppresses a rise in the temperature of the storage space S. In particular, since the air passage Ab2 of the inner wall 30 and the inner roof 40 is formed by using the projection board 36 having a large number of projections 35, the contact area with the air is large, so that the heat Exchange is performed efficiently.

Further, also on the partition wall Wa, fresh air from the outer air passage Aa flows and air circulation with the inner air passage Ab is also performed.
An increase in the temperature of the storage space S is suppressed. As described above, since the two systems of the outer air passage Aa and the inner air passage Ab are provided and have a double structure, the synergistic effect of the two passages surely suppresses the temperature rise of the storage space S, and therefore, Thus, a situation that adversely affects the contents is reliably prevented.

In the above embodiment, the shapes of the outer air passage Aa and the inner air passage Ab are not limited to those described above, but may be formed in any manner. In addition, it goes without saying that the overall shape of the warehouse is not limited to the above.

[0020]

As described above, according to the warehouse of the present invention, since the air passage through which the air flows is provided inside the side wall and the roof, even if the outside air temperature rises, the heat flows through the flowing air. Since it can be transmitted and released, it is possible to suppress a rise in the temperature of the storage space, and therefore, it is possible to prevent a situation that adversely affects the stored material. In particular, when the outside air temperature is high such as in summer, it is extremely effective. Further, even when the outside air temperature is low, the transmission of cold air can be suppressed by the air passage, so that the accommodation space can be kept warm and a situation that adversely affects the accommodation can be prevented. Furthermore, since the structure is provided with an air passage, the environment of the accommodation space can be improved without using an expensive air conditioner, and equipment costs and running costs can be kept as low as possible. Can be improved.

[0021] And also, an air passage, since it is configured with two systems of an outer air passage and the inside air passage, it is possible to reliably suppress an increase in the temperature of the accommodation space by the synergistic effect of both passages, the outside air temperature The effect of keeping the heat when the temperature is low is high, so that it is possible to more reliably prevent a situation in which the contents are adversely affected.

Further, the air inlet opening provided in the outer wall portion, since the provision of the air outlet portion to the outer roof section, the outer air passage, the air outlet section by introducing fresh air from the air inlet opening Air can be exhausted from the outside, so that ventilation can be performed at all times. Therefore, even if the outer wall and the outer roof are heated, heat can be transmitted to the air flowing through the outer air passage and released, so that the air can be further released. In addition, an increase in the temperature of the housing space can be suppressed.

Further, since at least one of the air inlet and the air outlet is opened and closed according to a temperature change, when the outside air temperature is low, the opening is closed to allow snow to flow into the outside air passage. It is possible to prevent situations such as blowing in, cold air, etc., and it is possible to keep the temperature of the storage space without significantly lowering the temperature. Since the opening is opened according to the temperature rise, the air volume can be adjusted to allow proper ventilation, whereby the rise in the temperature of the storage space can be suppressed. Can be maintained in an appropriate environment, so that a situation that adversely affects the contents can be more reliably prevented.

Furthermore, since the inner air passage is constituted by a closed space provided continuously with the floor, the inner wall portion of the side wall, and the inner roof portion of the roof to circulate air, the inner wall portion and the inner wall portion are formed by a rise in temperature. Since the temperature of the floor is lower than that of the inner roof, the air can be circulated by this temperature difference, and the flowing air can be cooled by a relatively low-temperature floor of concrete or the like. Since heat exchange can be performed, equipment costs and running costs can be further reduced.

Further, the inner air passages of the inner wall and the inner roof are joined by using a board having a large number of projections, with the sides having the projections facing each other, and formed by a space formed between the projections. As a result, the contact area with air is increased, so that there is an effect that heat exchange can be performed efficiently.
