Abstract

PURPOSE:To prevent turbulence in an air-conditioner, control a blow-off air velocity and thereby enable comfortable conditioning of air by a structure wherein a blow-off chamber part in the air conditioner is made to have a layered structure and devices for opening and closing a plurality of blow-off passages are disposed for control. CONSTITUTION:A blow-off chamber 5 in a cabinet 1 is made to have a layered structure by providing partition plates 8a and 8b therein, so as to prevent turbulence in blow-off passages 5a, 5b, 5c and 5d. Moreover, devices 9a and 9b for opening and closing the blowing passages are disposed so as to control the quantity of air, and thereby a blow-off air velocity is controlled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having a blower section, a heat exchanger section and a blowout chamber section in a cabinet.

[0002]

2. Description of the Related Art In a conventional air conditioner, the blowout chamber has a single-layer structure, and the blowout air velocity is not adjusted.

[0003]

In the above prior art, in an air conditioner having a blower section, a heat exchanger section and a blowout chamber section in a cabinet, conditioned air that has undergone heat exchange is blown out into a room through a blowout passage. Before that, there was a heat loss due to the wall surface of the blow-out chamber part, and because the blow-out passage of the chamber part had a single-layer structure, it was impossible to adjust the blow-out air velocity during the small air volume operation.

In particular, during a small air volume operation in the heating operation, the temperature distribution in the air-conditioned room is deteriorated due to the characteristic of a natural phenomenon that the wind speed from the outlet is slow and the warm air is light. Therefore, there is a problem that comfort in an air-conditioned room is impaired.

[0005]

In an air conditioner having a blower section, a heat exchanger section, and a blowout chamber section in a cabinet, an apparatus for opening and closing the blowout passageway having a layered structure in which a partition is provided in the blowout passageway It is characterized by the provision of. Further, in the air conditioner, an opening / closing device arranged in the blowout passage is interlocked with the airflow control according to the airflow control.

[0006]

In the heating operation and the cooling operation, since the blowout passage of the blowout chamber portion has a multi-layer structure, turbulent flow in the blowout passage can be prevented.

Further, by disposing the device for opening and closing the blowout passage, the plurality of blowout passages can be opened and closed according to the blown air volume, heat loss in the blowout passage of the blowout chamber portion can be suppressed, and a small airflow amount can be obtained. It is possible to secure the blowing air velocity at the time. Thereby, the reaching distance of the conditioned air can be secured, and the comfort of the air-conditioned room can be enhanced.

Further, when the air conditioner is operating at the maximum air volume, it is possible to increase the blowing wind speed by opening and closing a plurality of blowing passages. This allows
It is possible to increase the ceiling height margin, which is one of the installation conditions for air conditioners.

EXAMPLES Examples of the present invention will be described below with reference to FIGS.
Will be explained. A conventional example is shown in FIGS.

The embodiment shown in FIG. 2 is an air conditioner having a blower 2, a heat exchanger 3 and a blowout chamber 5 in a cabinet 1, and blowout passages 5a, 5 in the blowout chamber 5 are provided.
Partition plates 8a, 8 are provided to make b, 5c, 5d multi-layered.
This is a structure provided with b. Furthermore, the structure is such that devices 9a and 9b for opening and closing the outlet passages 5a and 5b are provided.

With this structure, the conditioned air that has passed through the heat exchanger 3 from the blower 2 is placed in the blowing chamber 5 with the partition plate 8a,
By providing 8b, a plurality of outlet passages 5a, 5b, 5
It will pass through c and 5d. At this time, the blowing passages 5a, 5b, 5c, and 5d in FIGS. 2 and 4 are subdivided with respect to the conventional blowing passages 5a and 5b in FIGS. 1 and 3, and are disturbed by reducing the cross-sectional area of the blowing passage. The flow can be prevented. Further, when the air volume is large, the devices 9b and 9a for opening and closing the outlet passages 5a and 5d are positioned in the vertical direction, and when the air amount is small, the devices 9b and 9a for opening and closing the outlet passages 5a and 5b.
Is for controlling so as to be positioned in the horizontal direction. As a result, it is possible to secure the blowing air velocity at the air outlets 7a and 7b during the small air volume operation, the arriving distance of the conditioned air becomes longer than in the conventional case, and the comfort can be improved.

Further, when the ceiling height of the room to be installed in the air conditioner exceeds the conventional ceiling height, the devices 9b and 9a for opening and closing the blowout passages 5a and 5b during a large air volume operation are made horizontal. By controlling it to be positioned, the air outlet 7
It is possible to increase the blowing air velocity of a and 7b as compared with the conventional case. As a result, it is possible to increase the ceiling height margin, which is one of the installation conditions for the air conditioner, and to expand the range of buildings in which the air conditioner can be installed.

[0013]

According to the present invention, a partition is provided in the blowout passage of the blowout chamber to form a multi-layered structure, and a device for opening and closing one or a plurality of locations of the blowout passage is provided. The reaching distance of the conditioned air can be secured, and the comfort of the air-conditioned room can be enhanced. In addition, since the blowout passage is provided with a partition to have a multi-layered structure, turbulent flow in the blowout passage can be prevented and noise can be reduced. Furthermore, when the air conditioner is operating at the maximum air volume, the above structure can increase the reaching distance of the conditioned air, and the ceiling height, which is one of the installation conditions of the air conditioner, can be increased. It is possible to increase the margin.
