Abstract

PURPOSE:To enable to perform the change-over operation for the total heat and the sensible heat according to the condition, also enable to adjust selectively the ratio between the above heats by a method wherein heat exchanging elements are joined in honeycomb form by intersecting at right angles respectively a humidity exchangable element and a humidity non- exchangable element. CONSTITUTION:An intaking air A is introduced through the odd numbered stages, that is, 1, 3 and 5 stages of a mouthpiece 16, moved through shells, discharged to the odd number stages of a mouthpiece 15; a discharging air B is discharged to the even numbered stages of the mouthpiece 16 through the shells B from the even numbered stages, that is, 2, 4 and 6 stages of the mouthpiece 15. A total heat element 11 is interposed as a separating wall between the odd numbered stage and the even numbered stage, accordingly, a temperature exchanging and a humidity exchanging are performed. Next, with rotating the shell by 90 degree, in case that the air intaking and air discharging are performed through the mouthpieces 15, 16 similary as the above operation, the sensible heat element 12 as the separating wall is interposed between the odd numbered stage and the even numbered stage, accordingly, only the humidity exchanging is performed. Further, to add to the changing-over of the total heat and sensible heat by 100%, the ratio of the total heat and sensing heat can be adjusted by several stages.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a ventilation system that takes in outdoor air and exhausts indoor air.

(Prior Art) A heat exchange type ventilation device is used, which is installed at the boundary between indoors and outdoors, and is rotated by a fan to perform forced ventilation through air supply and exhaust ports that open indoors and outdoors. Figure 5 shows the principle diagram, where the arrow indicates air supply, and the arrow B
When the outdoor temperature is lower than the indoor temperature, heat moves from the exhaust side to the air supply side via the partition wall 1, and so-called heat exchange occurs. At this time, humidity is also exchanged. In order to be able to exchange humidity at the same time as heat exchange during ventilation, a total heat exchange element 1 such as paper impregnated with lithium chloride is used.

Figure 6 shows an example of a conventional device, in which the total heat elements 1 are arranged in parallel and housed in the case 2, and air is supplied in the direction of the arrow in, and exhausted in the direction of the arrow B, using a fan (not shown). It is.

However, in cold winter regions, there is a problem in that indoor water vapor condenses in the ceiling, closets, etc., making it unsuitable for use as a total heat exchange element. Therefore, in cold regions in winter and places where dehumidifying ventilation is desired, such as bathrooms, so-called sensible heat exchange elements, such as plastic, have been used, which do not exchange humidity at all but only exchange heat. Therefore, it was not possible to use dehumidifying ventilation and humidity exchange together in either case.

Further, if there is a pressure difference between supply and exhaust in the element part, the reinforcing material 3 has been used because a soft material such as lithium chloride impregnated paper would close the air passage on the low pressure side.

(Object of the Invention) The present invention has been proposed to improve the above-mentioned drawbacks, and is a ventilation system that can arbitrarily adjust total heat exchange (exchange of both temperature and humidity) and sensible heat exchange (exchange of only temperature). The purpose is to provide the following.

(Disclosure of the Invention) FIG. 1 shows a honeycomb-shaped element used in the present invention. In the figure, (a) shows the element 11 for total heat odor change that exchanges humidity and temperature, (b) shows the sensible heat exchange element 12 that does not exchange humidity, and (c) shows the element 11 for both elements 11 and (2). They are arranged perpendicularly to each other and assembled into a nikum shape.

As shown in FIG. 2, these are housed in a case 13, and a rotating shaft 14 is attached in the axial direction. This rotating shaft allows the case 13 and the cell to be rotated in the direction of the arrow υ.

15 and 16 are mouthpieces attached to the openings at both ends of the case 13. Arrows indicate air supply, and arrow B indicates an exhaust route. The exhaust air enters from the odd-numbered stages of the mouthpiece 16 and exits from the odd-numbered stages of the mouthpiece 15. A total heat element 11 is provided between the supply air and exhaust paths. Because of the presence of the gas, an exchange of temperature and humidity, that is, a total heat exchange, takes place between the supply air and the exhaust air.

Next, how to properly use total heat exchange and sensible heat exchange will be explained. In FIG. 3(A), the supply air A enters the mouthpiece 16 at odd-numbered stages, that is, 1°3.5 stages, passes through the cell, and exits at the odd-numbered stages of the mouthpiece 15.
passes through cell B from the even-numbered stages of the mouthpiece 15, that is, 2, 4, and 6, and exits to the even-numbered stages of the mouthpiece 16. Since the total heat element 11 is interposed as a partition between each odd-numbered stage and even-numbered stage, temperature and humidity are exchanged.

Figure 3 (b) shows the state in which the cell can be rotated 90 degrees from the state (a) to the state (b), and the mouthpiece 1
5. From 16, when air is supplied and exhausted in the same way as in case (a), since the sensible heat element 12 is interposed as a partition between the odd-numbered stage and the even-numbered stage, only the temperature can be exchanged. be exposed.

In either case, the element that is not a partition wall can serve as a reinforcing material that prevents the air passage from being blocked due to a pressure difference between supply and exhaust. The means for switching the air supply and exhaust air paths as described above is not limited to the rotation of the rotating shaft.

FIG. 4 shows a cell divided into several parts. In the figure, 13, 13' power: total heat exchange, 13r sensible heat exchange, but if each of 13, 13', and 13' can be rotated, it will not only be possible to switch between 100% of total heat and head heat. It is also possible to adjust the ratio of total heat and sensible heat in several stages. By increasing the number of divisions, it is possible to achieve an arbitrary ratio. If you control the humidity with a humidity level of 7/3, you can automatically adjust the humidity to your desired level.

(Effects of the Invention) The present invention has a heat exchange element section in the middle of the air supply and exhaust port, and is installed at the boundary between indoors and outside the mold.
In the ventilation device 4 that performs forced ventilation using a fan, the heat exchange element is configured such that an element that can exchange humidity and an element that does not exchange humidity are connected orthogonally to each other to form a honeycomb shape. This has the effect that it is possible to switch between total heat and sensible heat, and the ratio can be adjusted arbitrarily.
