ようにしている。In this type of greenhouse, dew condenses on the inner surface of the inner curtain of the two-layer curtain due to the temperature difference between the inside and outside of the curtain, and the condensed water droplets fall and cause crop diseases and quality defects. Conventionally, the inner curtain of a two-layer curtain uses a moisture-permeable sheet, such as a non-woven fabric, to allow the inner curtain to absorb or allow moisture to pass through at night. This is to prevent condensation.

There are some problems that can cause such problems.
本発明の目的は、このような問題をより改善した温室内
カーテンへの結露防止方法を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a method for preventing dew condensation on curtains in a greenhouse, which further improves the above-mentioned problems.

ものは、屋根裏を伝って軒方向に流れる。"Operation" Since the method of the present invention involves partially opening a transparent curtain continuously or intermittently at night, for example, in the case of an opaque curtain or a two-layer curtain provided below a transparent curtain, A part of the moisture inside the curtain is absorbed by the opaque curtain, and another part passes through the opaque curtain, or a part of the outer transparent curtain is continuously or intermittently opened. Moisture is led from the open area to the attic of the greenhouse, and condensation in the attic of the greenhouse flows along the attic toward the eaves.

とかできる。If the curtain is installed on the outside of an opaque curtain or a transparent curtain, a part of the inner transparent curtain is opened, and the moisture inside the transparent curtain is guided upward from the open part. Some of the dew is absorbed by the opaque curtain, and some of it passes through the opaque curtain and is guided toward the attic of the greenhouse.The condensation that condenses on the attic flows toward the eaves along the attic, and condenses on the inner surface of the transparent curtain. Is it possible to prevent this?

全閉状態となり、結露防止の制御を終了する。In this embodiment, when sunrise or sunlight is recognized, the drive device 25.25 is activated to fully open the opaque curtains 2, 2 to let in the light. When it is opened, the microcomputer 3's [transparent curtain fully close operation ONJ] command causes the drive device 15.15 or the winding rod 14.14 to further rotate to the winding method of the transparent curtain 1. When the "operation time" has elapsed, each drive device 15 is stopped by the command "transparent curtain fully closed operation OFF" from the microcomputer 3, the transparent curtains 1, 1 are fully closed, and the condensation prevention control is ended.

のは当該屋根裏を伝って両軒方向に流れる。In the above embodiment, at night, the transparent curtain 1.1 is in a partially open state (half-closed or half-open state) with the central part of the frame 11 along the direction of the pitcher's force as shown in FIG.
The opaque curtains 2, 2 are in a fully closed state. At night, the inside of the greenhouse is controlled by the microcomputer 3 and the heater 4 is operated to maintain a temperature higher than the outside air, so moisture is generated inside the opaque curtain 2.2 and the curtains 20 and 20. Moisture rises and some parts are breathable opaque curtains 2
．． 2 or the other part is opaque curtain 2.2
It passes through the partially open portion of the transparent curtains 1, 1 and rises to the attic of the greenhouse a, and the condensation on the attic flows in the direction of both eaves along the attic.
したかって、室内すの湿気かかなり増加しても不透明カ
ーテン２．２の吸湿量は飽和状態にならないからその内
面に露結しない。Therefore, even if the humidity in the room increases considerably, the amount of moisture absorbed by the opaque curtain 2.2 does not reach a saturated state, so no dew condensation occurs on its inner surface.

で内側の透明カーテンの内側には結露しない。Even if the positional relationship between the transparent curtain 1.1 and the opaque curtains 2, 2 is reversed as shown in Figure 81, the inner transparent curtain 1.
By leaving a part of the greenhouse open, the humidity in the room will rise through the open part, part of it will be absorbed by the outer opaque curtain, and the other part will pass through the opaque curtain and enter the greenhouse a. Since the condensation rises to the attic, it does not condense on the inside of the inner transparent curtain for the same reason as mentioned above.

露に伴なう作物への悪影響とを比へると、後者の方の影
響かはるかに大である。The above-mentioned frost prevention method leaves the transparent curtain l partially open at night, but either causes some heat loss in the room b or increases heating costs due to heat loss and prevents dew condensation. Compared to the negative impact on crops, the latter is far more significant.

定すれば充分である。The degree to which the transparent curtains should be left open at night should be determined as appropriate depending on the crops being grown, the temperature difference inside and outside the greenhouse, the indoor temperature that needs to be controlled, etc., to the extent that heat loss is minimized and dew condensation is prevented as much as possible. Alternatively, depending on the conditions described above, it is sufficient to set the area within three to five-fifths of the front area of the transparent curtain 1.

Such control can be easily implemented using a microcomputer, a timer, a timer circuit, etc.

Since the transparent curtain of the two-layer curtain is left partially open continuously or intermittently during the night in a greenhouse where the curtains are closed, it is extremely inexpensive and effectively prevents condensation on the curtain. Deciding what to do,
This prevents the harmful effects of condensation on crops.
