Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention enables simultaneous axial flow and radiant flow through a single outlet.
Axial flow that can be switched to one or the other depending on usage
The present invention relates to a combined outlet for radiant flow.

[0002]

2. Description of the Related Art For example, in factories, kitchens, etc., heat generation and radiant heat are large due to their environmental characteristics, and the target area is wide. Therefore, an air conditioning system by general ventilation is not always effective. Therefore, generally, a spot air-conditioning system that directly supplies conditioned air to a limited range centered on the worker is adopted. In this case,
Usually, an axial flow outlet such as a ceiling nozzle outlet, a slot outlet, or a pan carver is used.

[0003]

However, in this spot air-conditioning system, only the limited area such as the work area is subject to air conditioning from the purpose, and the blowing area is almost fixed. It cannot follow when moving. As a method of coping with this, it is unavoidable to plan the spot air conditioning over the range including the moving area in advance, or to ignore the spot air conditioning from the beginning and plan the air conditioning.

In addition, when the ceiling is low and the outlets are close to each other, there is a problem that an appropriate working environment cannot be obtained, such as an excessively high wind speed or an excessively small spot target area at the axial flow outlet. doing.

[0005] Further, in a multipurpose hall or the like where the use is changed for each event, such as an exhibition hall or a party hall, it is convenient if it is possible to selectively use the axial flow or the radiation blow according to the use.

Therefore, the main object of the present invention is to carry out spot air conditioning by means of axial flow blowing, while at the same time making it possible to blow conditioned air around it by means of radiant flow blowing, and it is possible to switch to either one if necessary. The purpose is to provide a combined outlet for axial flow and radial flow.

[0007]

The object of the present invention is to provide a single outlet device in which an axial flow outlet and a radiant flow outlet are formed independently of each other, and each of these outlets is used for adjusting a flow rate and closing. This can be solved by providing a damper.

[0008] As a specific example of the device, for a cylindrical body having a large number of radiating air outlets formed therearound, the radiating air outlet is provided with an air volume adjusting and closing damper.
An axial outlet is provided at the distal end of the cylindrical body, and an air flow adjusting and closing damper is provided at the axial outlet.

As another device, an axial flow outlet is provided substantially at the center of the lower surface of the blow-off body, and a radiant flow outlet is provided around the axial flow outlet, and blown air is diffused around the radiant flow outlet. A blowout guide is provided for each of the axial flow outlets and the radiation flow outlets, and an air outlet device provided with a damper for air volume adjustment and closing, or an axial flow outlet of a pan carousel installed on a ceiling. An air outlet device having a cylindrical body having a number of air outlets for radiation at the end and having an air outlet for axial flow at the tip, and having a damper for adjusting air volume and closing each of the air outlet for air flow and the air outlet for axial flow. And the like.

In these cases, the tubular body is a cylindrical body, and the air flow rate adjusting and closing damper is internally provided by slidingly contacting the inner wall of the cylindrical body having a large number of through holes in the peripheral wall. It can be a cylinder. Further, a pan carousel can be directly attached as the axial flow outlet.
Further, a blowing guide may be provided in an eaves shape with respect to the radiation blowing outlet.

[0011]

In the present invention, in one blow-off device, the axial-flow blow-out outlet and the radiation-flow blow-out outlet are formed independently of each other, and each of the blow-out outlets is provided with a flow rate adjusting and closing damper. Therefore, by adjusting the air flow rates of the axial flow outlet and the radiant flow outlet and adjusting the closing damper, the conditioned air is sent to the area around the spot target area while performing the spot air conditioning for the limited work area. Therefore, proper air conditioning can be performed over a wide range to some extent.

If the ceiling is low or the position of the outlet is close to the work area for some reason, the outlet on the axial flow outlet side is throttled, and the outlet on the radiation outlet side is fully opened. By doing so, the wind speed can be arbitrarily adjusted in the work area to an appropriate value, and air conditioning over a wide range becomes possible.

On the other hand, if it is desired to use only one of the axial flow blowout and the radiation flow blowout depending on the use condition, the axial flow blowout and the radiation flow blowout are controlled by adjusting the air flow and opening / closing the closing damper. By opening only one of them and closing the other, conditioned air can be selectively blown out only from one side.
