The sheets are of different shapes, flat and corrugated,
and forming a network of continuous parallel conduits for the flow of both media. The corrugated sheet supports the flat sheet along the crests of the corrugations and thus supports the conduit laterally. The rotating body is of conventional cylindrical shape, and the conduits extend parallel to the axis of rotation and open out from two flat sides of the rotating body.

As a ventilation system to supply fresh air. Each air stream is therefore provided with a respective inlet and outlet separate from the other air streams and connected to a separate area of the side of the rotor where the conduit opens.

役をする。 Traditionally, such rotating bodies have been made of fibrous non-combustible materials such as asbestos paper or, alternatively, foils or sheets of porous material such as porcelain materials. A sheet of material of this type serves as a carrier for a hygroscopic substance, preferably a hygroscopic salt solution such as the most commonly used lithium chloride.

るため、研磨とミーリング加工とを必要とする。 Rotating bodies of the above type made of porous foils or sheets can have special characteristics such as non-flammability, high capacity for moisture exchange and good mechanical strength. However, manufacturing a rotating body with these properties requires a large number of operations, which results in a rotating body that is relatively expensive and time consuming to manufacture. In order to provide the necessary mechanical strength, especially when wet, the material of which the sheet is made must be impregnated with several substances, and after the sheet is corrugated and shaped into a rotating body,
This impregnation must be carried out. Furthermore, immediately after completing these manufacturing steps, the circumferential surface of the rotating body must be finished, requiring polishing and milling to obtain the necessary flatness and precision.

れる。 The rotating body is manufactured using a particularly advantageous method of using two strips of aluminum foil with a thickness of 0.03 mm to 0.1 mm. One strip is corrugated with a height of 1 to 3 mm, and then the strip is bonded to the other strip, which remains flat, using a simple adhesive, for example as detailed in the above-mentioned patent application. The so-called single corrugation is thus formed into a cylindrical body of revolution of the required dimensions.

加と分解の危険とをさらに最小にする。 According to the invention, aluminum foil is treated with an aqueous solution of aluminate chloride in the form of potassium aluminate, sodium aluminate or lithium aluminate or mixtures thereof. Treatment or impregnation with an aqueous solution takes place in a first step by immersing the finished rotary body in a bath of a 10-15% aluminate solution or by pouring such a solution onto the rotary body. The concentration is preferably 16 in the solution.
~17% aluminate. The bath has a temperature at or somewhat below room temperature, such as 18°C, and the time is relatively short, for example 3 minutes. During this step, the grooves of the rotating body are at least partially filled with an aluminate solution. During this method or processing step, the surface of the foil is corroded so that a porous coating can later be attached to it. When the rotating body has been lifted from the impregnation bath so that the solution exits the groove to the required extent, this coating is created in the following method or process step. However, a film of solution must remain on the surface of the rotor, and this is best accomplished by moving the groove to a horizontal position immediately after draining the solution. The liquid entering the grooves of the rotor from the impregnating bath is altered or changed with the generation of heat, so that the foil experiences a substantial heat increase. A portion of the liquid, aluminum, then precipitates and adheres to the surface of the foil as a hygroscopic coating of mainly hydrogen oxide, while at the same time hydrogen gas escapes. The reaction continues for a time longer than the time of impregnation, possibly as long as water remains in the channel. When the reaction has stopped, wash the rotating body to remove water-soluble residues. To prevent fractures in contact between the coating and the foil carrier as a result of thermal stresses,
It is advantageous to slowly cool the rotating body before scouring. For example, if the rotating foil is used for 2 days (24
The increase in particle size of the coating and the risk of decomposition is further minimized when the coating is given the opportunity to age in moisture for a period of time, such as 2 hours).

ウムから成る。 As described above in the first method or step, the etching of the surface of the foil is completed in order to give it the possibility of forming a fixed seat for the porous coating of aluminum hydroxide. Although the effect on aluminum foil itself is very large, the second
10 to 20 on each side of the foil in the second treatment step.
Provides an additive coating with μm (micron) porosity.
For example, at a thickness of 50 μm the weight increase on the foil can be about 10%. The main component of the coating consists of several different types of aluminum hydroxide taken from the impregnating solution and not from the transformation of the aluminum itself.

る。 The treatment according to the invention should preferably be carried out after the rotating body has been manufactured. This method has been demonstrated to have a valuable effect on the strength of rotating bodies. A type of crosslinking appears to occur between the porous sheets at the surfaces between the contacting foils, which results in a strengthening of the joint between the corrugated strips.

しにフオイルの表面へ驚ろくほどよく付着する。 The hygroscopic coating can be concentrated in a first treatment step by repeated impregnations in an aluminate solution. Additionally, ground or powdered inorganic solid adsorbents, such as silica gel, can be introduced into the aluminate solution at some stage of the impregnation process. Such powders adhere surprisingly well to the surface of the foil without reducing the adsorption properties to any significant extent.

ずることを立証した。 The hygroscopic properties obtained using the above method are based on adsorption properties and, as mentioned in the introduction, the production of rotating bodies using highly porous foils made of asbestos or ceramic materials together with lithium chloride as the hygroscopic substance. It has been demonstrated that this yields moisture exchange properties comparable to those obtained in .

る。 In many cases where rotating bodies are used in conjunction with ventilation, there is a risk that dirt in the discharged air, such as fat or oil, will cover the surface with a thin film, which may be present if the hygroscopic coating consists of a solid adsorbent. Increases the diffusion of moisture to and from the hygroscopic coating,
It can be limited to some extent. The narrow pores and capillaries that allow moisture to condense therein can easily become blocked and stop working. If, on the other hand, the hygroscopic substance consists of a salt solution, the entire wetted surface will become active and the liquid will seep into the dirt film and break through the film.

酸化シリコンの追加の被覆を与える。 However, untreated aluminum foil does not have the ability to retain sufficient amounts of salt solution on its surface. As mentioned above, the porous coating obtained by treatment of aluminum foil with an alkali aluminate is capable of retaining a greater amount of salt solution than the untreated surface. Furthermore, the aluminate treatment provides a basis on which other coatings can be combined that further increase the porosity. A coating has already been described above in which the addition of powder to the sodium aluminate during the impregnation process provides an additional coating. The water absorption capacity of the foil surface can be increased considerably by this treatment method. Once treated with aluminate, the rotating body is immersed in water glass and then exposed to carbon dioxide. This provides an additional coating of chemically condensed silicon dioxide which increases porosity.

適当であることが判明した。 It has been demonstrated that another lithium salt, lithium nitrate, does not actually cause corrosion of aluminate treated aluminum foils. At the same time, lithium nitrate provides the foil with very good hygroscopic properties within the relative humidity range, ie above 10-20% relative humidity for the simultaneous exchange of moisture and heat in question here. Calcium bromide and sodium chloride have also been shown to be significantly less corrosive to aluminate-treated surfaces than lithium chloride, but they are not as good as lithium nitrate. Calcium bromide has proven itself to be particularly suitable as a hygroscopic agent.
