Description

  The present invention relates to an air conditioning system, and more particularly to a duct air conditioning system using a rectangular duct installed in a ceiling space or the like.

2. Description of the Related Art In recent years, in office buildings and the like, there is an example in which a design that exposes and arranges equipment and air-conditioning ducts without using a ceiling material or a base material is used to eliminate the feeling of pressure in an indoor overhead space. In addition, the introduction of grid system ceilings that can relatively freely arrange the positions of air-conditioning outlets, lighting, and the like in accordance with the arrangement of personal spaces at the interior construction stage is also in progress.
On the other hand, for the purpose of reducing the number of inspection ports on the ceiling surface from a design standpoint, a technique has been proposed that makes it possible to use both an air conditioning air control port and an inspection port (for example, Patent Document 1). As shown in FIG. 5, the air outlet installation structure 100 according to the same document is connected to the air outlet 101, which is detachably disposed in an opening 107 formed in the ceiling surface 103, and the air outlet 101. A flexible duct 103 that is connected to the tip of the air-conditioning duct 102 that is fixedly installed and can be swung in a horizontal plane; one end that is disposed inside the ceiling and is pivotally supported by a vertical axis; Holding arm 104. With such a structure, the flexible duct 103 can be shifted to the left and right when performing maintenance and inspection of devices and instruments installed on the ceiling 108.

  Usually, in an office, a plurality of personal spaces are provided below one blowing panel (air vent). However, there are individual differences in comfortable temperature and air volume, and it is difficult to make air conditioning settings that make all the residents feel comfortable. For this reason, there is a need for a system that improves the air conditioning comfort by making it possible to adjust the wind direction and air volume according to each person's preference for each personal space.

In recent years, there has been a growing interest in the relationship between office layout and intellectual productivity, and there are cases in which users frequently change their layout.
However, the current situation is that no attention is paid to the air-conditioning outlets such as the ceiling surface, and a duct type air-conditioning system corresponding to each of the above problems has not been proposed so far.

The present invention is for solving the above-described problems, and particularly provides a duct air-conditioning system capable of improving the working environment in an office space and achieving both comfort and energy saving.
The gist of the present invention is as follows. That is, the duct air conditioning system according to the present invention is
(1) A duct air conditioning system that air-conditions a room by supplying warm or cold air by an air conditioning duct disposed in a ceiling space or the like,
A rectangular air conditioning duct having a plurality of openings at predetermined intervals in the longitudinal direction on the lower surface side;
An air outlet unit comprising air blowing means for blowing hot air or cold air, and configured to be detachably attached to the opening, and
The air outlet unit can be installed in the opening directly above the air-conditioning location.
It is characterized by that.

(2) In the invention of the above (1), the air outlet is further provided with a lighting device in place of or in addition to the air flow blowing means.

(3) In each of the above inventions, the power source of the air flow blowing means and / or the lighting device can be taken out from the adjacent power taps among the plurality of power strips arranged along the rectangular air conditioning duct. It is characterized by comprising.

  According to the present invention, particularly in an office personal space, it is possible to realize air conditioning and lighting according to the preferences of each resident, and also contribute to the suppression of energy consumption.

  In addition, when the office layout is changed, the interior work accompanying the change of the air vent and the lighting position can be minimized, so that the construction period can be shortened and the cost can be reduced.
