Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an air conditioner, and more particularly to an air handling unit type air conditioner in which a casing is divided into two chambers to form a U-shaped air passage. Regarding

[Prior art]

An example of this type of conventional air conditioner is, for example, Jikkou Sho 62-
No. 40246.

[Problems to be solved by the device]

In this conventional air conditioner, a muffling mechanism is provided inside the casing to reduce noise generated by the blower or the like. Therefore, there is a problem that the internal structure becomes large and complicated.

Further, since the blower, the muffling mechanism, the main filter and the like are arranged inside the blower chamber, there is a problem that the position of the blower opening is fixed to the upper surface of the blower chamber.

Therefore, a main object of the present invention is to provide an air conditioner that is simpler and more compact, and that can form a blower port at any position.

[Means for Solving the Problems]

This invention discloses a casing, a partition wall that divides the interior of the casing into a first chamber and a second chamber, an opening formed in a lower portion of the partition wall and connecting the first chamber and the second chamber, and an upper end of the first chamber. A suction port formed in the first chamber, a blower arranged in the upper part of the first chamber and for taking air into the first chamber from the suction port, and a heat exchange arranged in the lower part of the first chamber so that the main surface is inclined. The air conditioner includes a coil, an air filter arranged in the vicinity of the main surface of the heat exchange coil in the first chamber, and a ventilation port formed in the chamber wall of the second chamber.

[Action]

The blower is arranged immediately after the inlet of the first chamber. And
The air taken into the first chamber from the suction port by the blower flows into the second chamber through the air filter and the heat exchange coil arranged in the same first chamber, and the air blown to the arbitrary position in the second chamber. Sent out by mouth.

[Effect of device]

According to this invention, since the blower is arranged immediately after the suction port, the noise generated by the blower is generated in the process of passing through the first chamber and the second chamber. Absorbed by etc. Therefore, it is possible to reduce noise without providing a silencing mechanism that requires a large space as in the related art, and to make the internal structure smaller and simpler.

Further, since the blower, the air filter and the like are arranged in the first chamber together with the heat exchange coil, only the humidifier (or a part thereof) and the eliminator may be provided in the second chamber, if necessary. The blower port may be formed at any position on the upper surface, the side surface, or the lower surface of the second chamber. Therefore, the installation position of the air conditioner, the degree of freedom in designing the duct path, and the like can be significantly improved.

The above-mentioned objects, other objects, features and advantages of the present invention will become more apparent from the detailed description of the embodiments below with reference to the drawings.

〔Example〕

Referring to FIGS. 1A and 1B, the air conditioner 10 of this embodiment includes a casing 12. Inside the casing 12,
The partition wall 14 forms a first chamber 16 on the right side and a second chamber 18 on the left side. The two chambers 16 and 18 are communicated with each other by an opening 20 formed below the partition wall 14.
Further, on the upper surfaces of the first chamber 16 and the second chamber 18, that is, on the upper surface of the casing 12, an intake port 22 is formed on the right side and a blower port 24 is formed on the left side. However, the first chamber 16 and the second chamber 18
May be formed in the opposite direction.

A fan unit section 28 is formed by a support plate 26 in the upper part inside the first chamber 16, and a heat exchange section 30 is formed below the support plate 26.

In the fan unit section 28, from the inlet 22 to the first chamber
An air blower 32 for taking in air, that is, an impeller (not shown) in a fan casing 34, an electric motor 36 for driving the impeller, and the like are arranged in the air blower 16. The output shaft 38 of the electric motor 36 is directly connected to the impeller. The outlet of the fan casing 34 is passed through an opening 40 provided in the support plate 26 and the heat exchange section.
Communicated with 30.

Heat exchange section 30 includes pre-filter 4 in order from the top (upstream of air), as best seen in Figure 1B.
2. The main filter 44 and the heat exchange coil 46 are arranged in a stack so that the main surfaces thereof extend in the left-right direction (FIG. 1A) and are inclined.

Although not shown, an inspection door is formed on the front surface of the casing 12 for inspecting and replacing each air conditioner arranged inside the casing 12.

In this air conditioner 10, when the impeller inside the fan casing 34 is driven by the electric motor 36, air flows as shown by the arrows in FIGS. 1A and 1B. That is, the suction port
Air taken into the fan unit section 28 from 22 is sent out into the heat exchange section 30 from the opening 40 through the fan casing 34.

The air sent into the heat exchange section 30 is first removed of relatively large dust by the pre-filter 42, and then further finer dust is removed by the main filter 44. Then, heat exchange, that is, heating or cooling is performed by the heat exchange coil 46.

In this way, the air that has been subjected to the dust removal and heat exchange processing flows into the second chamber 18 through the opening 20 and is discharged from the blower port 24 into the room to be air-conditioned.

According to this embodiment, as can be seen from FIGS. 1A and 1B, the fan 32 that is the noise source, that is, the impeller in the fan casing 34 and the electric motor 36 that drives the impeller are formed inside the casing 12. Since it is arranged on the most upstream side in the air flow path, the first chamber 16 and the second chamber 18 are used as a muffling chamber, and the prefilter 42,
The main filter 44, the heat exchange coil 46, etc. can function as a silencer. Therefore, noise can be reduced without providing a conventional silencing mechanism, and the internal structure can be made smaller and simpler.

Further, since the pre-filter 42, the main filter 44 and the heat exchange coil 46 are arranged diagonally to increase the air passage area, the resistance of the air passing through these can be reduced, and the power and generation of the blower 32 can be reduced. Noise can be reduced.

Further, since the output shaft 38 of the electric motor 36 is directly connected to the impeller, a belt for power transmission is unnecessary, and it is possible to save the labor required for checking and replacing the belt in the past. Moreover, the pre-filter 42 and the main filter 44, which are frequently inspected and replaced, are arranged on the lower front side of the casing 12 so that they can be inspected or replaced by the inspection door (not shown) formed on the front surface of the casing 12. Because I am
The maintainability as a whole can be dramatically improved.

Further, since no air conditioner is arranged in the second chamber 18 and only air flows, the blower port 24 can be formed at any position on the chamber wall of the second chamber 18. That is, the air outlet 24 can be formed at the lower end of the second chamber 18 as shown in FIG. 2, or can be formed at the side surface of the second chamber 18 as shown in FIG. Therefore, the installation position of the air conditioner, the degree of freedom in designing the duct path, and the like can be dramatically improved.

If the air conditioner 10 is to have a humidifying function, for example, as shown in FIG.
Across the first chamber 16 and the second chamber 18 at the bottom of the inside of the humidifier 48
And the eliminator 50 is obliquely arranged in the second chamber 18. If the eliminator 50 is placed diagonally, the resistance of the air passing through the eliminator 50 can be reduced,
The power of the blower 32 and generated noise can be reduced.

If the blower port 24 is formed at the lower end or the side surface of the second chamber 18, as shown in FIG. 2 or FIG.
The humidifier 48 may be arranged in the lower part of the inside of the first chamber 16, and the eliminator 50 may be arranged in the vicinity of the opening 20 in the second chamber 18 substantially parallel to the partition wall 14.
