Abstract

PURPOSE:To permit the optimum temperature circumstance in a room, by a method wherein a mixing means, which mixes air passing through first and second heat exchanging means with the air passing through the first flow passageway in a casing, is provided in the title humidifier. CONSTITUTION:Wet air, passing through the second flow passageway 6 of a casing 4, is deprived of heat by passing through one side 9a of a heat pipe 9 and is transported to the other side 9b of the heat pipe 9, then, is exchanged by a first fluid 10 of a low temperature and the air is cooled. Accordingly, the temperature of the air, passed through one side 9a of the heat pipe 9, is reduced and the air is dehumidified. A second fluid 16 of a high temperature is deprived of heat by passing through the other side 15b of a heat pipe 15 and is transported to one side 15a to heat the air, dehumidified and reduced in the temperature thereof upon passing through one side 15a, whereby dehumidified and heated air may be obtained. Next, this air is mixed with humid air, passing through a first flow passageway 5, by a mixing means 20 whereby the air, having a higher temperature, may be obtained. This air is introduced into a vinyl house whereby the dehumidification of the inside of the house may be effected without reducing a temperature in the house substantially.

Figure 6 shows an interior of a greenhouse, for example, and in Figure 2, (1) is a vinyl house, (2) is a first fan installed above the entire surface of the greenhouse (1), (
3) is a second fan installed above the rear part of the greenhouse (1).

A variety of crops are grown in the greenhouse (1), but if the humidity inside the greenhouse (1) becomes too humid, the growth of the two crops may be hindered or diseases may occur on the crops. In order to prevent this, the first fan (2) installed above the entire surface of the greenhouse (1) and the greenhouse (
1) The second fans (3) installed above the rear surface are operated at any time.

The high humidity environment is alleviated by ventilating the inside of the vinyl house (1).

[Problem that the invention seeks to solve]

However, in the conventional device described above, the first fan (2) and the second fan (3) are installed above the greenhouse (1), so there is sufficient ventilation on the upper side of the greenhouse (1). This can reduce humidity to some extent. but.

There is almost no ventilation in the lower part of the greenhouse (1), especially around the crops.

Humidity can hardly be lowered. Therefore.

There were problems with the high humidity environment around the crops, which hindered the growth of the crops and caused diseases. In addition, the temperature inside the greenhouse (1) decreases due to ventilation by the first fan (2) and the second fan (3).

Alternatively, when outside air is introduced by the second fan (3) and exhausted by the first fan (2), there is a problem that the temperature inside the greenhouse (1) further decreases.

This invention was made to solve the above-mentioned problems, and an object thereof is to provide a dehumidifying device that can create an optimal humidity environment indoors.

[Means for Solving the Problems] The dehumidifying device according to the present invention divides the inside of the housing into a first flow path and a second flow path to separate indoor humid air introduced from one side. Inside the second flow path, the other side is placed outside the casing, and the indoor humid air flowing through the second flow path and the low-temperature first
A first heat exchange means for exchanging heat with the fluid is provided, and the first heat exchange means is located on the downstream side of the first heat exchange means, and one side is disposed within the second flow path and the other side is disposed outside the casing. A second heat exchange means is provided for exchanging heat between the dehumidified and low-temperature air and a high-temperature second fluid. A mixing means is provided for mixing the air flowing through the heat exchange means and the air flowing through the first flow path of the casing.

[Effect]

In the dehumidifying device of the present invention, indoor humid air introduced from one side of the housing is divided into a first flow path and a second flow path,
The indoor humid air flowing through the second flow path is heat exchanged with the low temperature first fluid by the first heat exchange means and dehumidified to become low temperature air, and the low temperature air is exchanged with the high temperature second fluid. The air which has been heat exchanged by the second heat exchange means and which has passed through the first heat exchange means and the second heat exchange means and the indoor humid air which has passed through the first flow path of the casing is mixed by means of mixing means. It is mixed at

The supply pipe (17) of the second supply and discharge device (19) is connected to the first supply and discharge device (
13) Exclusion 1! 1' (12), that is, the first fluid (10) which has been heated to a high temperature after being heat exchanged by the first heat exchange means (8) is used. There is.

(20) is arranged on the other side of the casing (4), and the air that has passed through the first heat exchange means (8) and the second heat exchange means (14) and the first flow path ( 5) A mixing means for mixing the air flowing through the air, (21) is, for example, a mixing means (20).
The mixing means (20) is arranged on the downstream side of the plastic greenhouse (1) and introduces the moist air inside the greenhouse (1) into the housing (4).
This is a fan device that brings out the air mixed in the plastic greenhouse (1).

Humid air inside the greenhouse (1) is introduced from point A1, and a part of it passes through point A2 and is transferred to the first heat exchange means (
Pass through the one-way flight of 8) and then go to the second flight via point A3.
It passes through one of the heat exchange means (14) and reaches point A4. The remaining part passes through point A5, and the air that has passed through point A5 and the air that has passed through point A4 are mixed at point A6. The low-temperature first fluid (10) passes through point W1, passes through the other side of the first heat exchange means (8), and reaches point W2. The first fluid (10) passing through this point W2 is used, for example, as a second fluid (16), passes through the other side of the second heat exchange means (14), and reaches point W3.

Next, the heat exchange operation will be explained based on FIG. 3. The humid air at point A2 flowing through the second flow path (6) of the casing (4) is one-way to the first heat exchange means (8).
