[Effect]

Since the multi-component air conditioner of the present invention is equipped with multiple fans and outlet units, the amount of air blown can be controlled by the multiple fans, and the multiple outlet units can accommodate each of multiple zones with different load types. . Therefore, air conditioning equipment in multiple zones can be centrally installed and managed.

〔Example〕

Examples will be described below with reference to the drawings.

FIG. 1 is an internal configuration diagram showing one embodiment of a multi-component air conditioner according to the present invention, and FIG. 2 is an external view of the multi-component air conditioner shown in FIG. In the figure, 1 is an outlet unit, 2 is a hot and cold water coil, 3 is a cold water coil, 4 is a blower, 5 is a humidifier, 6 and 7 are filters,
8 is a drain pan, 9 is a bypass air duct, 10 is a return air duct,
11 is an automatic valve, 12 is a hot and cold water pipe, 13 is a cold water pipe, 14 is an air supply port, 15 is a return air port, 16 is an outside air intake port, 17 is an inspection door, and 18 is a partition wall.

As shown in the internal configuration diagram of FIG. 1, the multi-component air conditioner according to the present invention has a partition wall 18 that extends downward from the upper end into a central air conditioner section and a side return air passage 10 that also serves as a pipe shaft. The return air and outside air are introduced from above the return air duct 10, and are led from below the return air duct 10 to the plurality of air outlet units 1 through the central air conditioning equipment section. Therefore, in the central air conditioner section, from below, a pre-filter 7, a filter 6 consisting of a unit type or an electric precipitator are arranged, and a humidifier 5, a plurality of Air blower a4, cold water coil 3, and hot and cold water coil 2 are arranged.

Further, the cold water coil 3 and the cold/hot water coil 2 are arranged side by side, and a bypass air passage 9 is provided on the back side thereof. On the other hand, a cold/hot water pipe 12 is piped to the return air duct 10 where the cold/hot water coil 2 is arranged, and a cold water pipe 13 is piped to the return air duct 10 where the cold water coil 3 is arranged. Valve 1
Connected by 1. Although the control mechanism that controls all of these is not shown in the figure, for example,
They will be installed in other vacant spaces as appropriate.

Corresponding to the above internal configuration, as shown in the external view of Fig. 2, an air supply port 14 is provided at the center of the upper part, a return air port 15 is provided on both sides of the air supply port 14, and an outside air intake port 16 is provided on the side of the air supply port 14. Mouth 14
An inspection door 17 is provided below so that the air conditioning equipment section can be inspected. Therefore, when inspecting the equipment, by opening and closing the inspection door 17, each package shown in the internal configuration diagram in Figure 1 can be inspected and confirmed, and each componentized part can be replaced in a short time. It becomes possible.

As described above, the multi-component air conditioner according to the present invention has all necessary functions including peripheral functions,
It shall be integrated into the casing. The main features that differ from conventional air conditioners include cold and hot water pipes.
2, installation of piping such as cold water pipe 13, installation of automatically controlled pulp such as automatic valve 11, V of outlet unit 1
For example, it can serve as both an AV function and a mixing chamber.

Next, air flow in the multi-component air conditioner according to the present invention will be explained. Return air port 15 and outside air intake port 1
The air introduced from 6 passes through a return air passage 10 which also serves as a pipe shaft, passes through a pre-filter 7 and a filter 6, and is humidified by a humidifier 5 when humidification is necessary. A plurality of blowers 4 are installed so that the number of blowers can be controlled, and by controlling the number of blowers, the amount of air blown is controlled according to the needs of the room. The heat exchanger (coil) includes a cold/hot water coil 2 and a cold water dedicated coil 3.
The side is typically used for applications where air conditioning is required. Therefore, the amount of air blown is controlled by this blower 4, and the coil 2
．． 3, where the heat is exchanged, and the air is blown into the room from the outlet unit 1 for each system. In the air outlet 1, the air bypassed through the bypass air duct 9 and the coil 2.3 without passing through the coil due to the degree of heat load in the room.
through which heat is exchanged and mixed with air (mixing chamber), and the amount of air blown is adjusted (VAV function).

In this method, for example, as shown in the external view shown in FIG.
This is done by changing the area through which air passes depending on the positional relationship of the openings 0 formed in each.

The inner cylinder portion 20 is rotated as required by a motor M, which is controlled by a control mechanism.

In addition, for the flow on the water side, a return air duct 10 that introduces return air and outside air is used as a pipe shaft space, and cold and hot water or cold water is supplied there through cold and hot water pipes 12 and cold water pipes 13, but the amount of water is The automatic valve 11 is controlled by a control mechanism built into the air conditioner, and the amount of water is controlled to an appropriate amount according to demand.

The present invention is a multi-purpose heat source function-equipped type that is equipped with an air heat source heat pump function as a heat source, and has the function as the above-mentioned air conditioner by using refrigerant direct cooling or a heating coil for air cooling or heating. Can be used as an air conditioner.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, cooling and cooling/heating coils, filters, fans, piping, control mechanisms, etc. are provided as components, and a VAV function and a mixing chamber are also provided to support multiple zones. Since it is configured to do so, it can easily meet the diversifying demands of office buildings. Additionally, componentization makes it easier to maintain and replace parts. Furthermore, it is possible to achieve low noise and compactness, and it can be installed within the office, so the effective area ratio of the office space can be improved.
