In order to implement this, a plurality of blowing fans are formed inside the enclosure of the present invention. The purpose of the blowing fan is to exhaust indoor air to the outside and supply outdoor air to the indoor room. If ventilation conditions are implemented in only a part of a plurality of spaces, the blower fan does not operate 100%, and selective operation that matches the demand conditions must be implemented.

Therefore, an integrated blower controller is installed, and the integrated blower controller individually controls the first and second blower controllers. The first and second blower controllers detect the usage conditions for multiple demand spaces in real time, and each blower fan It is controlled in conjunction with each damper. The blowing fan controls the blowing volume by changing the rotation speed. In another embodiment, the motor rotation speed of the first and second blowing fans is maintained the same, and the blowing amount can be controlled by varying the angle of the blade.

The present invention (Examples 4-1 to 4-5) relates to injection molding of boxes and distributors containing antibacterial substances. The enclosure and distributor are manufactured by injection molding using thermoplastic resin. In order to homogeneously distribute the MOF powder inside the thermoplastic resin, the MOF powder is firstly molded in the form of pellets, and is mixed with the resin powder under selected conditions depending on the type of MOF to secondarily mold the product (box, distributor).

In order to maintain the functionality of the MOF powder during the injection molding process, the MOF powder undergoes a pre-drying process during pellet processing, and is characterized by being pre-treated at a high temperature for a long time during the pre-drying process. In particular, it is desirable that the temperature conditions be maintained at 120 degrees and dried for 24 hours. This has critical implications for moisture adsorption of MOF powder. Secondary molding (product injection); The temperature is maintained at 200 to 230 degrees during the process, which is to maintain homogeneous mixing conditions of PP, PS, ABS resin and MOF powder. The temperature range has a critical meaning for optimal homogeneous arrangement of MOF due to the influence of viscosity depending on the type of resin.

The present invention (Examples 5-1 to 5-6) is an additional invention in which a duct and a diffuser are added.

The first duct and the second duct may be directly connected to the enclosure or may be connected through a distributor.

The first duct and the second duct flow air, and moisture in the air may cause condensation. The condensation must have its own sterilizing effect because it creates a habitat for harmful bacteria inside the duct.

To solve this problem, the shape of the duct is circular or square. In the case of a square shape, the corners are rounded or chamfered. This is to prevent condensation water from being stressed and located in the bend.

Alternatively, the enclosure is manufactured from a material containing MOF material. Therefore, the enclosure itself can have a sterilizing function and a dehumidifying function.

As another example, a normal duct material is used, but a coating layer made of MOF material is formed inside. Therefore, the effect of cost reduction can be achieved by causing a sterilization effect only by coating rather than manufacturing the entire duct with MOF material.

As another example, a box-shaped sterilizing flow passage unit with a plurality of flow passages uniformly formed is installed inside a normal duct. The sterilization flow passage part can be used as a single unit or in plural units. When using multiple devices, they can be used at regular intervals, or multiple devices can be integrated into one unit.
