Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an underfloor type air conditioner installed on the ceiling above and below the floor so that maintenance can be performed more easily than either the floor or the ceiling and the machine room space is extremely reduced.

[0002]

[Prior Art]

 Conventionally, when installing an air conditioner in a building such as a building, a large machine room was provided, and an air conditioner, control equipment, etc. were installed in this room, or a ceiling-embedded type was installed in the ceiling.

[0003]

[Problems to be solved by the device]

 However, when a machine room is provided, a large machine room is required, and the ceiling-embedded type can be maintained only from the room side, making maintenance difficult.

The present invention aims to make an air conditioner installed on the ceiling above and below floors so that a maintenance inspection can be easily performed from the upper floor surface and / or the lower ceiling surface. To do.

[0005]

[Means for Solving the Problems]

 The present invention was made in order to achieve the above-mentioned object, and an air conditioner is installed in the ceiling space between the upper and lower rooms of a multi-story building, and cold air or warm air is supplied from this air conditioner as needed. The main point is that the discharge is made into the rooms on the upper and lower floors, and maintenance openings are provided on both the upper floor and the lower floor to allow maintenance from the floor or ceiling.

【Example】

 An underfloor type air conditioner of the present invention will be described below with reference to the illustrated embodiment. In the figure, 1 is the floor of a room on the upper floor of a multi-story building, 2 is the ceiling of the lower floor, and there is a required gap between the floor 1 and the ceiling 2, and the upper floor is The air conditioner 3 is installed in the space between the floor and the ceiling on the lower floor. In this air conditioner 3, a filter 4 is arranged at the suction port for sucking the heat exchange air like the conventional product, and is guided to the coil 5 via this filter 4. The air passing through the coil 5 is subjected to a desired heat exchange, and then is passed through the blower 6 from the muffling chamber 7 via the duct 8 or from the blower 6 via the duct 8 to the floor 1 on the upper floor side or Connected to the outlets 1H, 2H of the ceiling 2 on the lower floor side, cool air or warm air from the air conditioner 3 is sent to the room on the upper floor side. From the outlet 1H on the floor, or the outlet 2H on the ceiling of the lower room. More so as to discharge each.

Further, the air conditioner 3 is installed in the space C between the upper floor 1 and the lower floor 2, but the repair / inspection of this air conditioner can be performed from the corridor side without performing from the room. It may be installed in the space C above the corridor.

Further, the air outlets 1H and 2H provided on the floor / ceiling, particularly the air outlet 1H on the floor, are provided with a lid for closing the air outlets 1H when not in use. When hot air is blown out, warm air is blown from the floor from the outlet 1H on the upper floor side to efficiently heat the room on the upper floor side, and when blown out cold air, from the outlet 2H on the lower floor to the floor below the ceiling. Blow out to the side room for efficient cooling.

The hot air and the cold air can be discharged to the rooms on the upper and lower floors at the same time, and the air outlets 1H and 2H and the air conditioner 3 installed in the corridor are required. It is connected by a long duct.

[0010]

[Effect of the device]

 The underfloor-installed air conditioner of the present invention has an air conditioner installed in the ceiling between the upper and lower rooms of a multi-story building, and cool air or warm air is discharged from the air conditioner to the upper and lower rooms as required. In addition, maintenance openings were provided on both the floor on the upper floor and the ceiling on the lower floor to allow maintenance from the floor or ceiling, so the space that was previously a dead space was used. However, it does not require an air conditioner installation space, and it has the advantages that repairs and inspections can be easily performed from both the ceiling and floor, and that the air conditioning can be performed simultaneously on the second floor with a single system.
