DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a device for forming a zone (air-conditioned space) by an air curtain, and more particularly to a ventilation means thereof.

[Conventional technology]

FIG. 7 shows a conventional zone-forming fluid adjusting device filed by the applicant as Japanese Patent Application No. 1-217125.

In FIG. 7, 1 is a guide member, 2 is an axial blower that is a jet flow generating means, 3 is a fixed wall such as the ground or floor, and 4 is an air conditioner that is a fluid adjusting means.

The guide member 1 has an umbrella-shaped guide surface 1a extending radially while inclining so as to descend from the central portion toward the outer peripheral edge.

The axial blower 2 has a cylindrical casing 21, an impeller 22 coaxially arranged therein, a motor 23 for driving the impeller 22, a stay 24 for fixing the motor 23 to the casing 21, and an air blower. It comprises a guard 26 attached to the suction port 25 and a guide 28 attached to the air outlet 27, and is connected to the upper central portion of the guide member 1 by a bracket 29.

A heat exchanger 43 is arranged inside the casing 41 of the air conditioner 4 so as to face the air suction grill 42, and a blower 44 arranged at the center of the heat exchanger 43 is driven by a motor 45. The motor 45 is supported by the indicator plate 46.
A plurality of adjusted air outlets 47 are arranged on the circumference of the top of the housing 41, and the inclinations of these adjusted air outlets 47 can be freely changed.

A table 48 is attached to the upper part of the housing 41 via a vibration-proof material 49, and a control panel is attached to the side surface of the housing 41 below the table 48.
50 is installed.

The column 5 hermetically penetrates the bellows 49 at the center of the top of the housing 41, the lower end thereof is supported by the support plate 46, and the guide member 1 and the jet flow generating means 2 are fixed to the upper end thereof. If the pillar 5 is placed in the hollow, an electric wire or the like can be wired inside the pillar 5.

The condensing unit 6 is connected to the air conditioner 4 via a refrigerant pipe 7. In the casing 61 of the condensing unit 6, a compressor 62, a heat exchanger 63, and this heat exchanger.
A fan 64 for blowing air to the 63, a diaphragm 65, etc. are stored.

Thus, the guide member 1 is supported in the space 8 by the pillars 5 so as to face the fixed wall 3 with a predetermined space therebetween, and the axial blower 2 is integrated with the fixed member 3 outside the upper portion of the guide member 1. It is supported by columns 5. The air conditioner 4 is arranged on the fixed wall 3 below the central portion of the guide member 1 inside the zone 9 described later, and the condensing unit 6 is arranged outside the zone 9.

Then, when the operation panel 50 is operated to operate the axial blower 2, the impeller 22 is rotationally driven by the motor 23.

Then, the air outside the guide member 1 enters the casing 21 through the air inlet 25 through the guard 26, is urged by the impeller 22, and jets toward the center of the umbrella-shaped guide surface 1a of the guide member 1. It becomes A and is ejected. And an umbrella-shaped guide surface
It collides with the central portion of 1a and is guided by the guide 28 to become a flow B along the guide surface 1a and diffuse toward the outer peripheral edge 1c. Then, a film-shaped annular jet C is discharged from the entire circumference of the outer peripheral edge 1c obliquely downward. As the jet C advances, the direction of the jet C gradually changes and becomes downward, and the jet C collides with the fixed wall 3 and collides with the fixed wall 3.
Towards the outside of zone 9.

As a result, an air curtain extending from the outer peripheral edge 1c of the guide member 1 to the fixed wall 3 is generated by the annular jet C, and a locally closed space surrounded by this air curtain, that is, a zone 9 is formed in the space 8 in the guide member. There is a limit between 1 and the fixed wall 3.

Since the annular jet C has a property of attracting and dragging the air around it, the recirculation flow D is generated in the zone 9 and the pressure in the zone 9 becomes smaller than the pressure in the space 8, thus, The streamlines of the jet C are bent by the mutual attraction of the annular jets C, and the streamlines of the jet C are determined so that the negative pressure and the centrifugal force acting on the jet C are balanced.

On the other hand, when the operation panel 50 is operated to cool the air conditioner 4 and the condensing unit 6, the refrigerant discharged from the compressor 62 of the condensing unit 6 enters the heat exchanger 63 and is sent by the fan 64 here. It is condensed by exchanging heat with the generated air, adiabatically expanded at the throttle 65, and then enters the heat exchanger 43 of the air conditioner 4 through the refrigerant pipe 7, and after evaporating here, it is condensed again through the refrigerant pipe 7. Returning to the unit 6, it is sucked into the compressor 62. At the same time, the blower 44 of the air conditioner 4 is rotationally driven by the motor 45, so that the air in the zone 9 passes through the air suction grill 42, enters the housing 41, and flows through the heat exchanger 43. After being cooled, it is urged by the blower 44 and blown into the zone 9 from the plurality of adjusted air outlets 47. And zone 9
It is recirculated inside, and in the process, a part of it mixes with the jet flow C to urge it and prevent the jet flow C from diffusing into the space 8. The drain condensed on the surface of the heat exchanger 43 during the cooling operation is discharged through the drain hose 52. Air conditioner 4
Since the specific volume of the air in the zone 9 becomes small during the cooling operation of, the pressure in the zone 9 becomes low, and therefore the jet C
By this, the zone 9 can be easily formed, and the inside of the zone 9 can be cooled.

When the air conditioner 4 is operated for heating, the refrigerant circulates in the direction opposite to that during cooling, and the blower 44 of the air conditioner 4 rotates in the direction opposite to that during cooling, so that the air in the zone 9 adjusts air outlets. It is sucked into the housing 41 from 47 and is heated in the process of passing through the post heat exchanger 43 which is urged by the blower 44, and then is blown from the air suction grill 42 into the zone 9.
Thus, the person M in the zone 9 is heated in the condition of a cold head heat. Note that the fan 44 may be rotated in the same direction as during cooling even during heating operation. In addition, the housing 41 of the air conditioner 4
If a dust filter or a deodorizing filter is arranged in the air flow path inside, the air in the zone 9 can be dedusted or deodorized.

Since the inside of the zone 9 is partitioned by the space 8 and the air curtain C, the noise of the space 8 can be prevented from entering the zone 9 and the inside of the zone 9 can be efficiently air-conditioned or purified. The equipment cost and operating cost of the air conditioner 4 are also low.

Further, since the inside of the zone 9 is only partitioned by the space 8 and the air curtain C, the person M therein can see the four directions through the air curtain C and freely go through the air curtain. You can go in and out.

[Problems to be solved by the device]

The conventional zone forming fluid treatment device has the following problems to be solved.

That is, the zone 9 surrounded by the umbrella-shaped guide member 1 and the air curtain generated by the annular jet C serves as an air-conditioned space.
