Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner that performs cooling and heating of a building or the like.
[0002]
[Prior art and its problems]
An air conditioner for air conditioning a building or the like is desired to be as small as possible so that the floor area of the building can be used effectively.
A conventional air conditioner has a structure shown in FIG. 3, for example, and air flowing into the casing 32 from the air inlet 31 is exhausted through an air filter 33, a blower 34, an air heat exchanger 35, and a humidifier 36. The air blower 34 is composed of a fan 38 and a drive motor 39.
[0003]
The blower 34 has a large length in the direction in which the fan 38 and the drive motor 39 are arranged. In the conventional air conditioner described above, the fan 38 and the motor 39 of the blower 34 are arranged side by side. The width of the harmony device is large.
Moreover, in the case of the conventional air conditioning apparatus shown in FIGS. 4 and 5, since the fan 41 and the motor 42 of the blower 40 are disposed in the front-rear direction, the depth of the air conditioning apparatus is large.
[0004]
4 and 5, when the gap between the discharge port of the blower 40 and the air heat exchanger 35 is narrow, the air from the blower 40 is concentrated and blown to a part of the air heat exchanger 35. Since the heat exchange efficiency decreases, in order to uniformly blow the air discharged from the blower 40 to the air heat exchanger 35, a large-volume air chamber 43 is provided to exchange air heat with the discharge port of the blower 40. The space | interval of the container 35 must be opened, and the width of the air conditioner is increased accordingly.
[0005]
OBJECT OF THE INVENTION
An object of the present invention is to provide an air conditioner in which the width and depth of the apparatus are small, and air from the blower is evenly blown to the entire air heat exchanger and heat exchange failure does not occur. There is.
[0006]
【means】
To achieve the above object, an air conditioner according to the present invention, the casing having an inlet and exhaust port on the upper surface, is divided into an intake port side and exhaust port side by the vertical partition plate bottom opening, An air chamber is provided on the intake port side in the lower part of the opening of the vertical partition plate, an air heat exchanger is provided on the exhaust port side, and a fan is attached to the rotating shaft of the drive motor to discharge the air horizontally. attaching one end of the discharge port to the discharge short pipe, Rutotomoni are relatively the inflow side of the air heat exchanger so as to face the other end of the discharge short pipe into the air chamber, the air inlet of the air heat exchanger the portion where the air discharged from the discharge short pipe definitive on the side is blown directly, the current plate mounting for dispersing the air discharged from the discharge short pipe, also the driving motor, the rotary shaft is vertical To be There as being provided the structure.
[0007]
【Example】
Embodiments of an air conditioner according to the present invention will be described below in detail with reference to specific examples shown in the accompanying drawings.
A casing 3 having an intake port 1 and an exhaust port 2 on the upper surface is partitioned into an intake port side and an exhaust port side by a vertical partition plate 4 having a lower opening 4a. 5, an air passage that reaches the exhaust port 2 through the blower 6, the air chamber 7, the air heat exchanger 8, and the humidifier 9 is formed.
[0008]
The blower 6 includes a fan 10 and a motor 11 that drives the fan. The driving motor is provided so that the rotation axis is vertical, and the fan is attached to the rotation axis of the motor, and the air Is discharged horizontally from the discharge port 10b of the fan.
[0009]
One end of a discharge short pipe 12 is attached to the discharge port 10 b of the fan 10, and the other end of the discharge short pipe faces the air chamber 7, and the air chamber 7 has a lower opening 4 a of the vertical partition plate 4. It is provided to cover.
[0010]
A rectifying plate 13 made of, for example, punching metal is attached to the air inflow side of the air heat exchanger 8. The rectifying plate 13 is not attached to the entire surface of the air inflow side of the air heat exchanger, but is attached to a portion where the air discharged from the discharge short tube 12 is directly blown, and discharge from the discharge short tube. By dispersing the air, the discharge air is made to uniformly flow into the entire surface of the air heat exchanger.
[0011]
The air heat exchanger 8 is provided on the opposite side of the air chamber 7 across the lower opening 4a of the vertical partition plate 4, and this air heat exchanger is supplied with cold water from the outside during cooling to cool the air. A coil 8a and a hot water coil 8b that warms air by supplying hot water from the outside during heating are provided.
Further, the humidifier 9 is supplied with water for air humidification from the outside so as to humidify the conditioned air to a required humidity.
[0012]
Next, the operation of the air conditioner according to the present invention configured as described above will be described.
Air that has been sucked into the casing 3 from the air inlet 1 (outside air or return air from the air-conditioned room) is dust-removed by the air filter 5, and is discharged from the air inlet 10 a of the fan 10 to the outlet 10 b and the outlet short tube 12. After that, the air is blown into the air chamber 7.
[0013]
At this time, pressure loss of the discharge air from the fan is prevented by the discharge short tube 12. The air blown into the air chamber 7 is blown to the rectifying plate 13, a part of which flows into the air heat exchanger 8 through a small hole in the rectifying plate, and the remaining air spreads to the side of the rectifying plate and rectifies. It flows into the air heat exchanger without passing through the plate.
[0014]
Therefore, the air blown out from the discharge short pipe 12 does not flow in a concentrated manner in a part of the air heat exchanger, and the wind pressure is dispersed and flows uniformly over the entire suction side of the air heat exchanger.
[0015]
In the air heat exchanger 8, air from the air chamber 7 is cooled by a chilled water coil 8a during cooling, heated by a heated water coil 8b during heating, and humidified to a required humidity by a humidifier 9, and then ducted from an exhaust port 2 or the like. Is sent to the air-conditioned room.
[0016]
[Operation and effect of the invention]
Since the air conditioner according to the present invention has the above-described structure, the following actions and effects can be obtained.
Air from the intake port is sent into the air chamber by the blower, cooled or heated to a required temperature by the air heat exchanger, and sent from the exhaust port to the air-conditioned room.
[0017]
Since the blower is provided so that the fan rotates on a horizontal plane, it is sufficient that the space for the blower in the casing is sufficient for the width and depth of the fan. The width and the depth can be remarkably reduced as compared with the blower of the conventional air conditioner provided.
[0018]
Moreover, since the baffle plate is attached to the air inflow side of the air heat exchanger at the portion where the air from the blower is directly blown, the air from the blower seems to flow in a part of the air heat exchanger. Therefore, even if there is not much space between the blower and the air heat exchanger, the air flows evenly into the entire air heat exchanger, and a decrease in heat exchange efficiency is prevented.
[0019]
Therefore, the air conditioner can be made smaller than the conventional one without causing a decrease in heat exchange efficiency.
