Description

The present invention relates to a technique for performing air conditioning in combination with an air conditioner indoor unit by circulating air in a house.

In residential air conditioning, individual air conditioning in which an air conditioner indoor unit is individually installed in each room to perform air conditioning is widespread. Although individual air conditioning can be easily installed, there is a temperature difference between the entrance, corridor, stairs, and other places where air conditioning air is difficult to reach.
As an air-conditioning equipment that is less likely to cause a temperature difference than individual air-conditioning, whole-building air-conditioning for houses has been proposed. For example, Patent Document 1 describes an air-conditioning control system for the entire building that uses the structural skeleton space of a house such as the attic as a return duct. In the whole building air-conditioning control system of Patent Document 1, a room temperature sensor and a static pressure sensor are provided in each room to control the air-conditioning capacity of one air-conditioning indoor unit installed behind the ceiling and the air volume of the ventilation fan installed in each room. doing.

The air-conditioning equipment in the entire building covers the entire house, is expensive, and requires a large amount of construction, so it cannot be said that it can be installed easily. In addition, existing equipment such as air conditioners may be wasted. It is not necessary to air-condition the entire building, but there are cases where you want to extend the air-conditioning range to places where the air from the air conditioner is difficult to reach or to adjacent spaces.
The present invention has been made to solve such a problem, and an object of the present invention is to provide an air-conditioning equipment that can be easily introduced and that makes the temperature and humidity uniform while utilizing the existing equipment.

In order to solve such a problem, the air circulation device according to the present invention is provided in the first space where the air conditioner indoor unit is installed, and has an air outlet located above the air conditioner indoor unit and the first space. A suction port provided in a ventilable second space for sucking air in the second space, a return air path serving as a path for air sucked from the suction port to be carried to the outlet, and a return air path. The first space is provided with a fan for moving the air in the return air path and a control unit for controlling the operation of the fan, and blows out the air sucked from the suction port from the air outlet. Air is circulated between the space and the second space.

According to this configuration, the air in the second space is sucked in from the suction port by the fan of the return air path controlled by the control unit, moves in the direction of the air outlet, and is blown out from the air outlet above the air conditioner indoor unit. Therefore, the air in the second space can be delivered to the air conditioner indoor unit. Further, when the air in the second space is sucked from the suction port, the air conditioned by the air conditioner indoor unit moves toward the suction port in the second space. Therefore, the air in the space from the air conditioner indoor unit to the suction port can be efficiently replaced by the conditioned air, and the temperature and humidity of the first space and the second space can be made uniform.
In addition, it is easier to install afterwards compared to the air conditioning in the entire building, and the required second space can be selected to easily expand the air conditioning range by the air conditioner.

In the air circulation device according to the present invention, it is preferable that the suction port is located on the ceiling of the second space and a duct is provided as the return air path.
According to this configuration, since the suction port is located on the ceiling, it does not affect the flow lines and the arrangement of furniture in daily life. Further, by providing a duct dedicated to returning air, the air in the second space can be reliably moved to the air conditioner indoor unit.

In the air circulation device according to the present invention, it is preferable that the duct is located on the ceiling along the ceiling of the first space and the second space.
According to this configuration, since the duct is arranged behind the ceiling, the air circulation device can be installed without spoiling the aesthetic appearance of the room and without narrowing the room.

In the air circulation device according to the present invention, it is preferable that the duct is located under the ceiling along the ceiling of the first space and the second space.
According to this configuration, it is not necessary to install the duct by entering the ceiling, and there is no risk of interfering with the building structural members such as beams, so that the air circulation device can be installed more easily.

In the air circulation device according to the present invention, a floor is installed over the first space and the second space, the suction port is located on the floor, and the space under the floor is a part of the return air path. It is preferable to use.
According to this configuration, since the floor is installed and the suction port is installed, it is not necessary to process the existing floor, and the space under the floor is used as a part of the return air route to effectively use the space. can do. In addition, since the suction port is on the floor, the temperature and humidity of the air near the floor can be easily made uniform. In addition, the floor surface temperature becomes the same as room temperature in winter, which increases comfort.

In the air circulation device according to the present invention, the control unit operates the fan when the air conditioner indoor unit is operating, and stops the operation of the fan when the air conditioner indoor unit is stopped. It is preferable to let it.
According to this configuration, since the fan can be operated only when the air conditioner indoor unit is operating, the energy consumption for operating the fan can be suppressed, and the labor of operation is not required.

According to the present invention, it is possible to easily introduce an air-conditioning equipment for equalizing temperature and humidity as needed while utilizing the existing equipment.
