[Industrial application] This device is used in air conditioners
The present invention relates to a horizontal built-up air handling unit.

[0002]

2. Description of the Related Art Conventionally, an air han unit shown in FIG. 1 has been mainly used as a cooling / heating air conditioner in a building or the like. However, in most of these, the drain pan is installed at the lower part of the heavy weight coil block B, and therefore it is impossible to remove and clean the drain pan, and of course, maintenance work below the fuselage is very difficult.
Moreover, a separate plenum chamber for blowing out must be separately attached to the upper part of the airframe, so that there is an unavoidable concern that the overall shape will be very bulky.

[0003]

In view of the above-mentioned drawbacks, the present invention locates the blower in the fan block C below and provides a proper space below the filter block A and the coil block B on the other hand. Maintenance corner D
The maintenance corner D is formed as
The drain pan can be easily installed and detached under the coil by using. Therefore, it is easy to put the drain pan in and out, which has been said to be impossible in the past, and the maintenance work inside the machine can be easily and surely performed from below the machine body. The purpose of the present invention is to provide a convenient air conditioner in which various pipes can be easily installed and housed.

[0004]

As an air conditioner according to the present invention as means for solving the above problems, an air inlet 2 is opened at an appropriate position such as the front and rear of the upper portion of a machine body 1, and a filter 3 is installed in the machine. Adjacent to the installed filter block A,
A coil block B formed by appropriately arranging a mechanism such as a cooling coil 4, a heating coil 5, a humidifier 6 and the like is connected, and an electric motor 7 and a blower 8 are provided on the lower side of the machine adjacent to the coil block B.
And a fan block C formed by obliquely installing a partition plate a at the upper part of the blower port of the blower 8 to form a blow-out chamber 9 in parallel with each other to form the airframe 1 in the structure of the filter block A. A characteristic feature is that a maintenance corner D having an appropriate area is formed below the coil block B, and the drain pan 11 is detachably arranged by utilizing a space portion of the maintenance corner D. Further, as described in claim 2, several ventilation holes b, b, b are provided at appropriate places in the corners such as the upper side or the side surface of the coil support frame 12 which supports the coils in the coil block B. As a result, the entire cool air that flows in the ventilation passage during cooling does not pass through the coil, but a part of the cool air flows through the ventilation holes b, b,
It is possible to prevent dew condensation that occurs in the machine by flowing through b, and to obtain better heat exchange efficiency.

[0005]

The present invention has the above-mentioned structure, and the air sucked into the machine through the suction port 2 flows through the fan block C to cool the coil block B and to the heating coils 4 and 5. The heat is exchanged to an appropriate temperature such as cooling and warming, and flows into the blowout chamber 9 formed in the fan block C by the rotation of the blower 8 and is sent to the outside as a predetermined cool and warm air from the blowout port 10. Further, when the inside of the machine is inspected or cleaned, since the maintenance corner D having an appropriate area is formed below the suction port 2, the maintenance work can be easily performed from below the machine body. The drain pan 11 can be easily put in and taken out, and therefore, cleaning the drain pan,
Various operations such as replacement are also easy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will now be described with reference to the drawings. The entire machine body 1 is composed of a filter block A, a coil block B, and a fan block C. A suction port 2 is opened at an appropriate location, and a filter 5 having an appropriate shape is installed in the air passage of the machine. In the coil block B, the cooling coil 4 and the heating coil 5 are supported by the coil support frame 12, and the humidifier 6 is provided side by side in the blower passage in some cases. The fan block C has a motor 7 and a blower 8 at the bottom.
And a partition plate a is obliquely provided in the upper air passage of the air outlet of the blower 8 to form the blowout chamber 9, and
Similar to the suction port 2, a blowout port 10 is provided at an upper portion, a front-rear portion, a side portion, and the like in a required direction, and communicates with a blowing passage of the blowout chamber 9. As described above, this invention comprises a filter block A, a coil block B, and a fan block C integrally connected to each other, and a space portion having an appropriate area is formed below the filter block A and the coil block B. The space portion is intended to be used as the maintenance corner D, and the drain pan 11 can be detachably accommodated in the maintenance corner D as well as the maintenance work, and other necessary mechanical members and pipes can be easily provided. It can also be installed. Depending on the structure of the machine body 1, the maintenance corner D may be formed only below the filter block A or below the coil block B, for example.

Further, several ventilation holes b, b, b are provided at appropriate positions in the upper corners or side corners of the coil supporting frame 12 which supports the coils in the coil block B, for cooling. Part of the cold air is passed through the ventilation holes b, b, b,
We will try to prevent dew condensation from occurring inside the aircraft.

Further, it goes without saying that the maintenance corner D is not limited to the above-mentioned model of the embodiment, and can be widely used in the structures of various other air conditioners.

[0009]

In the air conditioner according to the present invention, the blower 8 in the fan block C is positioned below, and the maintenance corner D is provided by forming the space below the filter block A and the coil block B. Therefore, it is easy to perform maintenance work inside the machine under the fuselage, which has never been possible in the past, and it is easy to perform various works such as attaching / detaching and cleaning the drain pan 11 by using the maintenance corner D. It has a great effect such as being performed. Moreover, since the partition plate a is obliquely provided in the corner of the fan block C and the blowout chamber 9 is integrally formed, there is no need to attach the plenum chamber separately as in the conventional case, and it can be provided at a very low cost. Of course, at the same time, since the partition plate a has a triangular chamber shape due to the oblique installation, the noise noise that flows out inside the machine is naturally eliminated and silenced in the chamber. Therefore, since the noise is extremely low, it is not necessary to install any other sound deadening mechanism. In addition, the pipes and members that are attached to the outside of the conventional machine can be accommodated in the maintenance corner D. As a result, there is also an effect that the loss due to the exposure of these members is protected, and the overall shape can be formed to be bulky with good design.

Further, as described in claim 2, the coil block
Cooling coil 4 and heating coil 5 in coil B
2 support the inner wall of the fuselage at an appropriate distance,
In addition, at the corners of the front and rear of the coil support frame 12.
Due to the provision of several ventilation holes b, b, b
Bypass air passages are naturally formed around the coil.
During cooling, a part from the suction port 2 is the vent hole b,
Generated in the cabin by passing through b, b and flowing into the bypass bus
In addition to preventing dew condensation from occurring, this is especially true with conventional models.
A purpose-built space for a by-pass air duct in the cabin
No need to remove and prevent condensation on the front of the grill
The entire height of the aircraft can be maintained without the need for an air circulation interval for
It also has the effect that it can be formed to be bulky.
