Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning structure capable of improving air conditioning efficiency, low cost and easy to construct.

[0002]

2. Description of the Related Art Conventionally, as a method for air conditioning a room, a hot and cold water panel is provided on the ceiling surface and a dehumidifier or an air conditioner for dehumidification is placed in the room for dehumidification during cooling. A method in which an air conditioner is installed on the ceiling provided with an air passage and air is blown into the air passage and the room. Have been adopted.

[0003]

However, the method using the hot and cold water panel has a problem that the cost is increased because a panel and dehumidifying equipment are required.

A method of installing an air conditioner in the ceiling air passage is a so-called convection mode in which air is blown directly into the room and air conditioning is performed only by convection, or so-called radiation in which air is radiated only from the ceiling surface by air flowing in the air passage. It is difficult to control the mode and the so-called semi-convection / semi-radiation mode in which convection and radiation are shared, which tends to cause a reduction in air conditioning efficiency, and there is a problem that maintenance of the air conditioner and the like cannot be easily performed.

The present invention is based on the provision of a movable valve in a fan coil device arranged on a double ceiling, and can easily switch between total convection, total radiation, and half convection / semi-radiation to improve air conditioning efficiency. In addition, the purpose is to provide an air conditioning structure that can be easily installed at low cost.

[0006]

In order to achieve the above object, an air conditioning structure of the present invention is a heat exchanger for exchanging heat with a heating medium supplied to a double ceiling composed of upper and lower ceiling plates sandwiching an air passage. And a fan coil device having a fan for blowing air, and in the fan coil device, the lower opening part of the air outlet including a lower opening part that opens in the room and a lateral opening part that opens in the air passage. A movable valve that can open and close the opening and the side opening is provided, and an intake port that sucks in air is provided.

It is desirable that the ceiling plate under the double ceiling can be removed below the fan coil device.

[0008]

The fan coil device is arranged on the double ceiling composed of the upper and lower ceiling plates that sandwich the air passage, and the fan coil device has a lower opening portion that opens in the interior of the air outlet and a lateral opening that opens in the air passage. A movable valve that can open and close the opening is provided. Therefore, the actuation of the movable valve causes total convection by opening only the lower opening, total radiation by opening only the lateral opening, and half convection by opening both the lower and lateral openings. -Semi-radiation can be easily switched and implemented, and optimal air conditioning for the indoor environment can be performed efficiently.

Further, since the fan coil device is used, duct piping is not required, and the additional work is only a double ceiling as compared with the convection type air conditioner. Therefore, the cost can be reduced, the work can be facilitated, and the labor can be saved. It can be planned.

In the invention of claim 2, when the ceiling plate below the double ceiling can be removed below the fan coil device, maintenance of the fan coil device can be easily performed without going up to the ceiling. You can do it.
