Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor blowing type air conditioning system.

[0002]

2. Description of the Related Art Recently, for the purpose of improving the indoor environment immediately after the start of an air conditioner, or to reduce the capacity of a heat source and an air conditioner by cutting the peak of the air conditioning load,
After the air conditioner is out of the required time, the air conditioner is operated for heat storage, and heat (including cold heat) is stored in the concrete slab frame in advance,
An air conditioning system using frame heat storage that can use this heat when air conditioning is required has been proposed. For example, see the specification and the drawings attached to the application such as Japanese Patent Application No. 9-27131.

In this air conditioning system, a closed space constituted by a building structure, for example, a hollow portion of a floor slab constituted by a floor slab is constituted as an air passage for storing and radiating heat. The basic configuration is such that an air passage of the floor slab is disposed at an appropriate position of an air-conditioned air passage that returns to an air conditioner through the air passage.

[0004] An example of such an air conditioning system will be described. For example, in the system shown in FIG. 9, air-conditioning air discharged from a discharge side 2 of an air conditioner 1 is supplied to a double floor 3 such as an OA floor and a floor slab 4. The air flows into the underfloor space 5 formed between the floors, and is supplied to the room space 7 of the room from the outlet 6 provided on the floor 3, and the ceiling panel 8 and the floor on the ceiling side are supplied from the suction port 9 provided on the ceiling panel 8 In a floor-blowing type air-conditioning system in which the air flows into a ceiling space 10 between the slab 4 and the air flows through the space 10 and flows back to the suction side 11 of the air conditioner 1, the floor slab 4 is constituted by a floor slab having a hollow portion 12. The hollow portion 12 forms a heat storage air passage for heat storage and heat radiation, and the conditioned air flows through the heat storage air passage as needed. A large number of parallel hollow portions 12 are connected to each other at the right end side in the drawing to form a serial path, thereby forming an air inlet / outlet at both ends of the heat storage air passage at one end of the floor slab 4. That is, it is arranged on the left end side in the figure. That is, in order to supply the conditioned air from the discharge side 2 of the air conditioner 1 to the heat storage air passage, a communication duct 13 is arranged below the floor slab 4 of the ceiling interior space 10 in a direction perpendicular to the hollow portion 12. A branch duct 14 is provided from the communication duct 13 to a communication port 16 provided at one end of each series path. On the other hand, the other end of the series path is communicated with the space 10 in the ceiling by the opening 15.

In such a configuration, the air conditioner 1 is operated only for a necessary time outside the time when air conditioning is necessary, particularly at night when the unit price of the electricity rate is low, and the conditioned air is mainly circulated through the heat storage air passage to circulate. By performing the heat storage operation, heat (including cold heat) generated by the operation of the air conditioner 1 is stored in the floor slab 4 constituting the hollow portion 12. During air conditioning, the air stored in the floor slab 4 is recovered by the conditioned air by performing an operation of flowing the conditioned air flowing in the living room space 7 to the heat storage air passage upstream or downstream thereof. 7 can be used for air conditioning. For example, the heat storage operation is performed during 10 hours from 10 o'clock in the evening to 8 o'clock in the next morning, and the heat is stored in the floor slab 4 and is radiated and used in the daytime. In the figure, solid and broken arrows indicate the flow of air-conditioned air during the heat storage operation, and the dashed-dotted arrows indicate the flow of air-conditioned air during the air-conditioning operation. A configuration in which a path that flows only to the space 10 in the ceiling and returns to the suction side 11 of the air conditioner 1 and a path that flows from the space 10 in the ceiling to the heat storage air passage and returns to the suction side 11 of the air conditioner 1 can be selected. A duct arrangement, a switching mechanism, and the like for performing such an operation are appropriately configured. Although the above example is a floor blowing method, it is needless to say that the present invention can be applied to a ceiling blowing method.

Conventionally, in a tenant building, it has been difficult to air-condition a plurality of small rooms (tenants) using a common air conditioner. This is because it is difficult to measure the air flow rate corresponding to the usage of the air conditioner when the air conditioning day and time zone are different for each tenant. Therefore, conventionally, it is common to install an air conditioner for each tenant, and the same applies to the case where the above-described air conditioning system using frame heat storage is applied.

FIGS. 10 and 11 show an example of a tenant building in which an air conditioner is installed for each tenant. FIG. 10 is a plan view showing a floor blowing section, and FIG. 11 is a view showing a communication duct section. FIG. As shown in these figures, the air conditioner room is installed facing each divided room, and the air conditioner installed in the air conditioner room performs floor blowing air conditioning for each room. At this time, when the large room is used, the amount of air supplied from the air conditioner is adjusted by each outlet 6. Note that, in FIG. 9 described above, the air volume adjusting devices of each outlet 6 are not shown.

[0008]

As described above, conventionally,
If the air conditioner is subdivided, an air conditioner is required for each tenant, and the following problems occur. a. The cost increases because the number of air conditioners increases. b. Since an air conditioner is installed in each room, the dedicated space is reduced and the rentable ratio is reduced. c. In order to create each tenant's section, it is necessary to remove and newly establish a communication duct. For this reason, there is a possibility that air conditioning of other tenants may be hindered during the division work of each tenant. d. When used in a large room, as described above, it is necessary to adjust the air volume for each of the air outlets 6 on the floor 3, and air conditioning unevenness may occur. e. As shown in FIG. 9, the communication duct is connected via a duct to a communication port formed at one end of a series path formed by a hollow portion, so that a space behind the ceiling is taken up and the range of the ceiling falls. . An object of the present invention is to solve the above problems.

[0009]

In order to solve the above-mentioned problems, according to the present invention, in a building having a double-floor room and a common corridor, an air-conditioning machine room is formed in a core, and a space below the common corridor is formed. A floor having an air passage formed by partitioning with a heat insulating partition wall, a communication opening between the air passage and a space under the floor of a room adjacent to the common corridor, and an air flow control device installed at the communication opening. This is to propose a blow-out type air conditioning system.

According to the present invention, in the above configuration,
The space behind the ceiling of the common corridor is partitioned by a partition wall having heat insulation to form an air passage, and a communication port is formed between the air passage and the space above the ceiling of the room adjacent to the common corridor. It is proposed to install an air volume adjusting device in the country.

According to the present invention, in the above configuration, the floor slab of the room has a large number of parallel hollow portions, and adjacent hollow portions communicate with one end of the floor slab to form a serial path. And, at the other end of the floor slab, a communication duct is provided to communicate with the communication port formed at one end of each series path, and the communication port formed at the other end of the series path communicates with the space above the ceiling. In addition to communicating with the air conditioner in the air conditioning machine room through the communication duct installed in the space above the ceiling, the space above the ceiling is communicated with the air conditioner in the air conditioning machine room through the air passage in the common corridor,
It is proposed to adopt a configuration in which an air flow adjusting device is installed at a communication opening communicating with the space above the ceiling.

According to the present invention described above, the space below the common corridor is separated by a heat insulating partition wall so that the conditioned air is passed through the air passage. Individual air conditioning for each tenant divided by one or a plurality of common air conditioners becomes possible.

[0013]

Is connected to the air conditioner of the air conditioning machine room 22 through the air passage 32 of the air conditioner.

FIG. 8 is an enlarged view showing the vicinity of the communication duct 13. In this embodiment, the communication duct 13 is formed by mounting the U-shaped frame 35 on the floor slab 4 corresponding to the row of the communication ports 16. It is constituted by fixing to. Therefore, in this configuration, the branch duct 14 as in the configuration of FIG. 9 is not required.
Further, an air volume adjusting device 36 is installed at another communication port of the series route, that is, at the communication port 15 communicating with the space 10 above the ceiling.

The operation of the present invention in the above configuration will be described below. First, FIG. 6 shows a heat storage operation state. Air-conditioned air from the discharge side of the common air conditioner 1 installed in the air conditioner room 22 is supplied through the communication duct 13. That is, the conditioned air passes through the communication duct 13 via the communication duct 13.
After flowing into the hollow portion 12 of the floor slab 4 and flowing through the above-described series path, the air flows from the hollow portion 12 to the ceiling interior space 10 via the communication port 15, and then the air volume adjusting device 34 is moved from the ceiling interior space 10. The second air passage 3 through the communication port 33 provided

FIG. 7 shows a state during the air conditioning operation in the daytime. In this state, the conditioned air from the air conditioner 1 in the air conditioner room 22 passes through the communication port 26 '. 1
And flows through the first air passage 25. Then, in the room 7 where the air conditioning is performed, the underfloor space 5 of the room 7
And flows out into the room 7 through the outlet 6 and is supplied to the air conditioner. On the other hand, the air in the room 7 enters the space 10 in the ceiling from the suction port 9 provided in the ceiling panel 8, and then reverses to the above-described heat storage operation, the opening 15 opens the hollow 1 in the floor slab 4.
2, after flowing through the series path, flows into the communication duct 13 through the communication port 16, and returns to the suction side of the air conditioner 1 in the air conditioner room 22 to be circulated. .

In the above operation, of the rooms 7 which do not need air conditioning, the air volume adjusting device 27 of the communication port 26 is fully closed, and the room 7 is supplied from the common air conditioner 1 to the first air passage 25. The conditioned air does not pass through the communication port 26. Therefore, by controlling the air volume adjusting device 27 to open and close, air conditioning for each tenant can be performed by the common air conditioner 1. In addition, by adjusting the air volume by the air volume adjusting device 27, air conditioning can be performed according to the size of the room 7 of each tenant, and air conditioning unevenness in a large room can be eliminated.

Next, in the floor slab 4, the ceiling space 10

By controlling the opening and closing of the air volume adjusting device 35 in this manner, an operation mode in which heat is stored and an operation mode in which heat is not stored can be switched.

On the other hand, when the air volume adjusting device 34 installed in the communication port 33 is fully closed, the air in the second air passage 33 does not pass through the communication port 26 during the heat storage operation in another room, so that the tenant is not occupied. Alternatively, it can be a holiday.

It should be noted that the present invention is not limited to the air-conditioning system utilizing frame heat storage, as shown in the above embodiments,
The present invention can also be applied to a conventional general air conditioning system.

[0022]

As described above, the present invention has the following effects. a. With one or a plurality of common air conditioners, individual air conditioning for each divided tenant becomes possible. In this case, the individual air conditioning can be applied to both an air conditioning system using the heat storage of the skeleton and a general air conditioning system not using the heat storage of the skeleton. b. By adjusting the air volume adjusting device installed at the communication port for communicating the first air passage with the underfloor space of the room, it is possible to eliminate uneven air conditioning even in a large room. c. Since the air-conditioning machine room can be centralized in the core,
The exclusive space of the room can be enlarged, and the rentable ratio can be increased. d. Even if there is a room that is not occupied, it can be handled by opening and closing control of the air volume adjusting device. e. When the communication duct for configuring the air-conditioning system using the frame heat storage is configured by attaching a U-shaped frame to the floor slab, the range of the falling ceiling can be minimized.
