Description

The present invention relates to a ventilation system that ventilates a room by providing an air supply port provided at an intermediate portion between upper and lower parts on a wall surface of the room and an exhaust port provided on a wall surface facing the room.

As a conventional ventilation system, for example, an air supply port and an exhaust port provided in a living room in a building and an outside air introduction port provided on an outer wall of the building and capable of introducing outside air into the building are provided. It is provided with a ventilation means for sending the outside air introduced into the building from the air to the air supply port, an operation information storage means, and a control means. The operation information storage means stores the operation information consisting of four operation modes and controls the means. Has proposed a building ventilation system that controls the operation of a blower means based on an operation mode selected from the operation information stored in the operation information storage means (see Patent Document 1). According to this building ventilation system, it is possible to efficiently reduce the heat buildup in the living room at night with less energy and realize a comfortable indoor environment.

In such a conventional ventilation system, as shown in FIG. 8, both the air supply port and the exhaust port are provided on the upper side of the room, and are indicated by arrows from the analysis result of the air flow. As described above, although it depends on the flow velocity that changes depending on the magnitude of the ventilation air volume, it flows linearly from the upper layer to the upper layer in the room, and the ventilation efficiency cannot be improved. That is, even if the ventilation air volume was increased, the flow velocity of the air flow was locally increased and ventilation was performed, and the air in the entire room could not be ventilated evenly and efficiently. For example, in order to prevent the infection of coronavirus, which is the cause of China virus, it is recommended to ventilate the room frequently, but even if the ventilation air volume is simply increased, efficient ventilation cannot be achieved. It will be. According to this, the purpose of preventing infectious diseases cannot be achieved, and extra energy for heating and cooling is consumed.
