Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a nozzle-type outlet structure of an air conditioner, for example, a nozzle-type outlet structure for blowing out cool air when air-conditioning a large space area such as a factory, a warehouse, and a stadium.

[0002]

[Prior Art]

 When performing heating and cooling in large areas such as factories, warehouses, and stadiums, there is a so-called bunker louver as an outlet structure that allows treated air to freely reach the target load. There are various types of blowout nozzle portions (cylindrical portions) at the tip of the bunker bar, and for example, the structure shown in FIG. 5 is typical. In this bunker bar, a circular opening 2 is formed in a duct 1, a collar-shaped member 3 is fixed to the opening 2, and the side surface of the collar-shaped member 3 is formed in an R shape. The fixing member 4 is fixed. A nozzle body (ball portion) 5 having a substantially semicircular shape is disposed in the fixing member 4 so as to be movable in any direction via its central axis, and the lower end portion side of the nozzle body 5 is cylindrical. Of the speech bubble section 6.

[0003]

[Problems to be solved by the device]

 In this bunker bar, when the cool air A is blown out from the blowing section 6, the surrounding untreated air B is attracted near the blowing section 6. The untreated air B is hotter than the cool air A, and therefore causes the condensed water 7 to be generated in the nozzle body 5 and the blowing portion 6. The condensed water 7 becomes water droplets and falls on the indoor floor, human body, devices, documents and other parts.

FIG. 6 shows a state in which the nozzle body 5 and the blowing portion 6 are inclined with respect to the central portion thereof, and in this case also, condensed water is generated in the same manner as described above.

As a countermeasure against these problems, there has been no particular solution in the related art. Usually, the cold water temperature is raised, or the return air is mixed in the duct 1 so that the surface temperatures of the nozzle body 5 and the blowout portion 6 are untreated air. Measures were taken to design the dew point temperature above A. However, in this way, in order to obtain sufficient latent heat and to secure the necessary cooling performance, it is necessary to increase the amount of water and to largely select the coils and fans of the air conditioner.

An object of the present invention is to solve the above-mentioned conventional problems, and to prevent the generation and fall of dew condensation water without restricting the setting conditions of cooling, which is a nozzle-type outlet of an air conditioner. To provide the structure.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a nozzle-type outlet structure of an air conditioner including a nozzle body and a blowing portion connected to the nozzle body, and at least the outer surface of the nozzle body and the blowing portion. And are formed of a polymeric water-absorbing material.

[0008]

[Action]

 During the cooling operation, untreated air having a temperature higher than that of the cool air blown out from the blowout portion is attracted to the nozzle body side around the outer periphery of the nozzle body and the blowout portion to generate dew condensation water on the surface thereof. The condensed water is retained on the surface of the nozzle body made of a polymer water absorbing material and on the blowing portion. The dew condensation water in the polymer water absorbent moves downward and reaches the inner wall surface of the blowout section, where it is evaporated and treated by the cool air passing through the blowout section, and is discharged to the outside as cool air.

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing an embodiment of the nozzle-shaped outlet structure of an air conditioner according to the present invention. In the nozzle-type outlet structure of this air conditioner, a circular opening 2 is formed in the duct 1, and a collar-shaped member 3 is fixed to the opening 2, and a side surface of the collar-shaped member 3 is A fixing member 4 having an R-shaped packing is fixed. A nozzle body (ball portion) 5 having a substantially semicircular shape is disposed in the fixing member 4 so as to be movable in any direction via its central axis, and the lower end portion side of the nozzle body 5 is cylindrical. Of the speech bubble section 6.

The nozzle body 5 is formed of the polymer absorbent sheet 7, and the outer surface and the inner wall surface of the blowing portion 6 are formed of the polymer absorbent sheet 7. The inner wall surface side upper end portion 6a of the blowing portion 6 is chamfered so as to form a similar inclined surface at the inner wall surface lower end of the nozzle body 5, thereby preventing an increase in pressure loss and noise generation. It is supposed to do.

As the material of the polymer absorbent sheet 8, a composite material of fine particles of a high-performance thermosetting resin and a reinforcing material such as a polyester nonwoven fabric is preferably used. This type of polymer absorbent sheet 8 has excellent hydrophilicity with a water absorption rate of 50% or more and a water drop absorbency of 1 second or less without uneven hydrophilicity.

The operation of the nozzle-type outlet structure of the air conditioner in the above configuration will be described with reference to FIG. The cool air in the duct 1 which has been cooled and dehumidified by passing through the heat exchanger is blown out as the main cold air A through the nozzle body 5 and the blowing portion 6. In this case, the untreated air around the punk louver has a temperature higher than that of the main cold air, and this untreated air is attracted by the blowing of the main cold air A and comes into contact with the nozzle body 5 and the blowing portion 6. When the nozzle body 5 and the blowing portion 6 are exposed on the metal surface, the amount of dew condensation water is large, but the surface of the nozzle body 5 is the polymer absorption sheet 7, and the dew condensation water is exposed on the surface by the water absorption action. There is no. The condensed water in the polymer absorbent sheet 7 forming the nozzle body 5 moves downward and a part of it reaches the inner wall surface of the nozzle body 5, where it is evaporated by the cold air passing through the nozzle body 5. It is processed and reaches the blow-off section 6 as cold air.

The dew condensation water that has moved from the polymer absorbent sheet 7 that constitutes the nozzle body 5 to the polymer absorbent sheet 7 that constitutes the blowout portion 6 moves downward inside the polymer absorbent sheet 7 and part of it It reaches the inner wall surface of the blow-out portion 6, where it is evaporated and processed by the cool air passing through the blow-out portion 6, and is blown out from the blow-out portion 6 as cold air.
