Description

{UNDER FLOOR AIR CONDITIONING SYSTEM WITHOUT MACHINE ROOM}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor takeout air conditioning system, and more particularly, to a floor takeout air conditioning system that eliminates a mechanical room required for installing an air conditioner.

In the past, most buildings have adopted ceiling ventilation systems. The ceiling ventilation system is configured to supply harmonized air into the residential area (office space) through the ceiling air duct connected to the machine room. When using this ceiling ventilation system, if the cool air from the ceiling reaches a person's residence below 1.8m, or even below 1.2m to 1.5m where the person is sitting, cool the upper hot air first So that the cooling efficiency is inevitably lowered. In the past, when indoor heating was important in the winter, and ceiling partition and furniture layout changes were small, ceiling ventilation system was appropriate in the past. However, cooling and cooling of equipment loads such as human body and computer should be considered important, There is a need for an air conditioning system capable of overcoming the disadvantages of the existing ceiling ventilation system.

Under this background, the newly proposed air conditioning system is a floor takeout air conditioning system. In the floor take-out air conditioning system, air conditioning air is supplied from the floor of the room, or more specifically, from the lower part of the access floor, as opposed to the ceiling take-out air conditioning system. This floor air-conditioning system provides high air-conditioning efficiency for the residential area because the air-conditioned air is supplied from the bottom side close to the sitting position of the person.

On the other hand, the conventional floor take-out air conditioning system essentially requires a machine room having a very large area in order to install a granular air conditioner. Therefore, due to the machine room where the air conditioner is installed, there is a risk of damaging the exclusive area within the building. In addition, since the conventional floor take-out air conditioning system requires an access floor in an indoor space and also requires an access floor in a machine room that does not require the taking out of the conditioned air, there is a disadvantage that construction / facility cost is high.

At this time, the air passage (AP), particularly, the vent hole (72) connected to the side passage (SP) is formed on the upper part of the partition wall (7) adjacent to the ceiling.

 The outer space duct 11 and the exhaust air duct 12 are formed in the core space CA in such a manner that the outer air duct 11 and the exhaust duct 12 are connected to the connection holes formed in the intermediate wall 2, To the air passage (AP). At this time, it is preferable that the position where the exhaust duct 12 is connected to the air passage AP is the upper part of the side passage SP close to the ventilation hole 72 described above, It is preferable that the position to be connected with the floor passage AP is directly through the floor passage BP or close to the floor passage BP.

As described above, the machine room-free floor take-out air conditioning system according to the present embodiment is arranged so as to be connected to the indoor space (OA) side air passage AP via the intermediate wall 2 while being disposed in the core space CA without a machine room (11) and an exhaust duct (12).

The machine roomless floor air-conditioning system according to the present embodiment includes a ventilation fan 13 disposed in the air passage AP, more preferably a floor passage BP under the access floor 6, Is provided in the bottom passageway (BP) on the inner circumference (IP) side of the indoor space (OA) downstream of the fan (13) to heat or cool the air supplied through the ventilation fan (13) And a first cooling / heating fan coil unit (14) which is disposed in the floor passage (BP) at an intermediate portion (MP) on the downstream side of the first cooling / heating fan coil unit (14) A fan terminal unit 15 for supplying air passing through the heating fan coil unit 14 to the indoor space OA on the access floor 6 or for sucking air in the upper indoor space OA on the access floor 6, And a second fan unit disposed in the bottom passageway (BP) on the outer peripheral part (OP) side and connected to the first cooling / heating fan coil unit (14) and / or the fan terminal unit And a second cooling / heating fan coil unit 16 for supplying cooling / heating air passing through the second floor 5 to the upper floor space OA of the access floor 6 from the outer periphery OP. In this case, the ventilation fan 13 is preferably located near the start end of the bottom passage BP adjacent to the lower end of the side passage SP, and the first cooling / Heating fan coil unit 14 is located between the ventilation fan 13 and the fan terminal unit 15 within the floor passage BP and the second cooling / heating fan coil unit 14 is located between the ventilation fan 13 and the fan terminal unit 15, .

The operation of the machine roomless floor takeout air conditioning system according to the present embodiment will be described as follows.

First, the outside air supplied through the outside air duct 11, which is connected to the L-shaped air passage AP through the inside space OA through the middle space wall 2 via the core space without the machine room CA and / Type air passage AP flows through the floor passage BP under the access floor 6 under the driving of the ventilation fan 13. This air flows through the inner bottom portion IP side floor passage BP Heating fan coil unit 14 installed in the first cooling / heating fan coil unit 14, and flows to the downstream side thereof. The fan terminal unit 15 provided in the bottom floor passage BP of the first cooling / heating fan coil unit 14 is connected to the first air / heating fan coil unit 14 via the air / To the indoor space (OA) above the floor (6). At this time, the fan terminal unit 15 may suck air in the upper indoor space OA of the access floor 6. The air passing through the first cooling / heating fan coil unit 14 and the fan terminal unit 15 flows through the second cooling / heating fan coil unit (not shown) provided in the bottom passageway BP on the outer peripheral portion OP adjacent to the window 16, and is supplied to the upper indoor space (OA) of the access floor (6). In this way, the cooling / heating air supplied to the indoor space OA cools or warms the indoor space OA, and also ventilates the contaminated air in the indoor space OA. The air in the indoor space OA flows into the side passages SP between the partition 7 and the intermediate wall 2 through the ventilation openings 72 and the air that enters the side passages SP passes through the exhaust duct 12, A fan duct unit 15, and a second air-heating fan coil unit 16, which are exhausted to the outside of the building through a side passage (SP) or through a side passage (SP) BP. At this time, it is a matter of course that the outside air and the ventilation can be mixed.

As described above, in the floor take-out air conditioning system according to the present embodiment, the exhaust duct 12 and the outside air duct 11 are directly connected to the air passage AP including the inside side side passageway SP and the floor passageway BP, A first cooling / heating fan coil unit 14 for heating / cooling the air flowing in the floor passage BP is provided on the inner peripheral portion IP side of the floor passage BP, And a second cooling / heating fan coil unit 16 for heating / cooling the air supplied to the access floor upper indoor space OA is provided on the first indoor / outdoor fan coil unit OP side, Since the fan terminal unit 15 for supplying the air in the floor passage BP to the upper floor space OA of the access floor is provided between the two cooling / heating fan coil units 16, Omission is possible. Therefore, the omitted machine room can be used for other purposes such as warehouse, and therefore, the exclusive area in the building can be greatly increased.
