Abstract

PROBLEM TO BE SOLVED: To perform a local or heating of only a place where a specific person is present when a pew number of persons are scatteringly present in a wide area. SOLUTION: This local cooling or heating method is carried out in such a way that an air curtain blowing-out device 2 is fixed to a duct 1 for deeding cooling or heating air, a downward-directed narrow air blowing-out port 3 enclosing a relative narrow range is formed at a lower surface of the air curtain blowing-out device 2, either cold or hot air is blown out of the air blowing-out port 3 toward a floor surface or a ground surface so as to form an air curtain 4 with cold or hot air flow and to enclose a space around a specified person, this enclosed space 6 is shut off against a surrounding area, and the cold or hot air in the air curtain 4 is heat exchanged with hot air within the aforesaid space 6 so as to cool or heat the space. An infrared ray generator is fixed to the air curtain blowing-out device 2 as a case may be, and the infrared ray is radiated into the space 6 during heating operation to improve a heating effect.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf driving range, a factory, etc.
The present invention relates to a local cooling / heating method for spot-wise cooling / heating only the place.

[0002]

2. Description of the Related Art When there are many people in a wide area,
When it is open to the outside like a golf driving range, it is extremely wasteful and extremely uneconomical to air-condition the whole, so conventionally, it is a spot that locally blows cold and warm air only to the place where people are. The air conditioner was being used.

[0003]

The conventional spot air conditioning described above blows cold air or warm air directly to a place where a person is present. In this case, since it is affected by the ambient temperature, the general indoor space is air-conditioned. Since the effect cannot be obtained unless the air conditioner is heated and cooled more strongly than in the case, there is a problem that the cold or warm air having a large difference from the ambient temperature may directly affect the health.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, according to the present invention, only a specific place where a person is located is locally surrounded by an air curtain composed of a cold air stream or a warm air stream to directly cool the human body.・ Without blowing warm air, it encloses a person with a cold / warm air curtain to block it from the outside, and also indirectly heats the air temperature of the enclosed space with the temperature of the air curtain to perform local cooling / heating. There is. Further, in the case of heating, infrared rays can be radiated into the area surrounded by the warm air flow to enhance the heating effect.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is an air curtain based on a cold air flow or a warm air flow, in which cool air or warm air is blown to a floor surface or the ground from an air curtain blower having a downward narrow air outlet that surrounds a relatively narrow area. To form a space to enclose a specific one or a small number of people, to block the enclosed space from the outside, and to exchange heat with the air temperature in the enclosed space due to the temperature of the air curtain. It is a local cooling and heating method for cooling or heating the space.

Further, a local heating method for enhancing the heating effect by radiating infrared rays from an infrared ray generator mounted on the air curtain blower within a range surrounded by blowing out the air curtain by the warm airflow from the air curtain blower. Is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments will be described in detail with reference to the drawings. FIG. 1 shows an example in which the present invention is applied to a golf driving range. A duct 1 for sending cooling and heating air above a position where a golfer stands in practice. As shown in FIG. 2, the air curtain blower 2 attached to the tip of the air curtain blower 2 has a circular lower surface, and an air outlet 3 having a narrow circular gap is formed near the circumference of the circle. Has been formed. The air curtain blower 2 and the blow-out port 3 are not limited to the illustrated circular shape, but can be formed in a square shape or the like.

An air curtain 4 consisting of a cold air stream or a warm air stream blown out from the air outlet 3 surrounds the golfer and reaches the floor surface 5 to confine the golfer in a space 6 which is surrounded by a cylindrical shape. The air temperature in the enclosed space 6 is cut off from the outside space and is heat-exchanged by the cold air flow or the warm air flow of the air curtain 4 and approaches the temperature of the air curtain 4 and becomes almost the same temperature in a short time. Become.

Reference numeral 7 denotes an infrared generator, which is attached to the lower surface of the air curtain blower 2 and emits infrared rays 8 toward the golfer downward. In the illustrated example, a ring-shaped one that radiates the infrared rays 8 in a substantially conical shape is shown, but one or several rod-shaped ones may be attached. Further, the infrared generator 7 may be attached to the outer peripheral portion other than the lower surface of the air curtain blower 2 so that the radiation direction is directed to the inside of the space 6.

[0010]

The present invention is embodied in the form described above and has the following effects.

When a small number of people are scattered in a large area, when locally heating and cooling only a person's place, the person is surrounded by an air curtain of cold and warm air to cut off from the external space, and the air curtain is cooled and heated. Air is cooled or heated by exchanging heat with the air temperature in the enclosed space, which cools or heats this enclosed space indirectly, unlike the conventional spot air conditioner that directly blows cold or warm air onto a person. Therefore, it is possible to locally form a comfortable environment with little adverse effect on the human body.

In the case of heating, the heating effect may be insufficient with only the air curtain, but a sufficient heating effect can be obtained by attaching an infrared generator.

Most of the equipment is an air curtain blower having a simple structure attached to a duct for blowing air from an air-conditioning equipment, so that it is inexpensive, and a cooling and heating effect can be efficiently obtained in a small area.
