Description

Manned outlet {INDUCING DIFFUSER}

The present invention relates to a attractor outlet.

For the purpose of reducing the blowing power, there is a low-temperature air-conditioning system for supplying air from an air outlet provided in an air-conditioned space such as a room with the supply air from the air conditioner at a lower temperature and a smaller air volume than usual.

In such an air conditioning system, when a general blown air outlet is used, since the supply air is low temperature and the amount of excitation is reduced, air draft does not diffuse and cold draft and condensation occur.

Japanese Patent Publication No. 7-41345

In order to prevent this, the same outlet as patent document 1 is proposed. In order to prevent deterioration of the diffusivity, a swirling vane is provided in this outlet, but the structure is complicated, which causes a large pressure loss and noise. In addition, condensation occurs inside the air outlet because the air is attracted from the indoor opening, which is the lowermost surface of the air outlet. For this reason, the heat insulation process of the whole ejection opening is needed. In addition, drafts are liable to occur because the low-temperature supply air and the attracted air are mixed unevenly.

In order to solve the above problem, the attraction draw outlet according to the present invention includes a main body which draws and mixes the air in the air-conditioned space with the supply air blown out from the outside, and blows out the mixed air into the air-conditioned space. And a plurality of air outlets for ejecting the supply air are annularly arranged, and the supply air for ejecting the inlet port from the air outlet is blown to the side where the wind of the air outlet blows. It is divided into each air outlet to attract air in the air-conditioning space, install an induction guideway for introducing the manned air through the entire circumference of the inlet between the inlet and the inlet, and on the side of the wind blowing the inlet , A mixed air blowing air for guiding the mixed air of the supply air and the manned air to the air-conditioning space The formation, and to attract the air from the conditioning space to avoid the formation of an air passage for guiding attracted informing the yuingu the most essential characteristics thereof.

According to the invention of claims 1 and 2,

(1) Since low-temperature supply air and hotter manned air are taken out from the inside of the main body, condensation on the air blowing side can be prevented. Therefore, the heat insulation of the attracting port and the mixed air blow-out winder becomes unnecessary, and the heat insulation processing range becomes small, and manufacture becomes easy.

(2) Since the manned air can be drawn from the entire circumference of the manned port, the pressure loss is small, and the amount of air drawn (mixed ratio) of the manned air can be secured with respect to the amount of air supplied. Therefore, the amount of air blown out of the mixed air can be increased, so that the diffusibility is good and the temperature variation is eliminated.

(3) Since the air ejection port and the inlet port are divided into annular (circumferential directions) or only a part of the annular (circumferential directions), the static pressure decreases and the airflow reach increases, so that the diffusivity is good.

(4) The ejection direction can be freely selected in one direction, two directions, three directions, and four directions simply by changing the number of divisions of the air ejection port and the attracting port according to the arrangement and space of the air-conditioning space.

According to the invention of claim 3,

(1) Since the supply air is swirled along the gap portion of the main body to spread out widely around the entire circumference, the mixed air can be taken out evenly to the air-conditioning space, and the diffusivity is not reduced. Its compact structure makes it compact and does not occupy space, reduces pressure loss, prevents turbulence, smoothly blows out, and reduces noise.

According to the invention of claim 4,

(1) Since air is drawn from the radially outer side of the main body and taken out from the radially inner side of the main body, contamination of the ceiling surface due to the Coanda effect does not occur. Therefore, the ceiling surface is beautiful and no maintenance is required.

According to the invention of claim 5,

(1) By simply changing the circumferential positions of the air ejection port and the attracting port, the air flow distribution corresponding to the heat load distribution in the air-conditioning space can be freely set, and the air conditioning efficiency is good, and the comfort is improved.

According to the invention of claim 6,

(1) Simply by pushing the bolt nut member forward and backward by screw motion, the axial position adjustment and the circumferential position adjustment of the ejection portion can be easily performed. For example, adjustment of the space | interval of a ceiling plate and a blower part, and adjustment of a blowout direction can also be combined.

According to the invention of claim 7,

(1) By swirling the mixed air in a swirling manner, it is possible to accelerate the extraction of the mixed air into the air-conditioned space, thereby improving the diffusibility.

Attracted air enters through the guideway 19 and is sucked from the entire circumference of the inlet 5 and mixed with the supply air. Therefore, the ratio of the supply air flow rate to the intake air flow rate to the mixed air discharge air flow rate can be increased as, for example, 6: 4. The mixed air is blown out in four directions toward the air-conditioning space S via the mixed air blowout air passage 6. For example, during cooling, condensation does not occur in the mixed air blower 6 because low-temperature supply air at 13 ° C. and attracted air at 27 ° C. higher than that are mixed. In addition, the supply air is set so that the absolute humidity is lower than the dew point temperature of the air-conditioned space S at the time of attracting and mixing, but can be changed.
