There is a problem that when the warm air in the room, which is induced as such, comes into direct contact with the portion of the outlet device 100 facing the indoor space, dew condensation occurs. Conventionally, in order to prevent such dew condensation, heat insulation treatment such as flocking or attaching a heat insulating material to the entire surface of the air outlet device 100 has been performed. In addition to the increase in the manufacturing cost, there is a problem that the manufacturing process is complicated and the manufacturing is troublesome. In addition, when the heat insulation treatment is performed on the surface of the outlet device 100, it is difficult to make the appearance harmonized with the surrounding ceiling surface or wall surface, and there is a problem that the installation location is limited. Furthermore, even if the heat insulation treatment is performed, the state in which the induced secondary air contacts the edge 101 does not change.
1 has a problem in that dust contained in the secondary air adheres and may become dirty or mold may occur.

For this reason, there has been a problem that the edge protruding from the ceiling surface or the wall surface may give a sense of incongruity, which does not match the surrounding situation.

することができる。As described above, according to the present invention, the outer nozzle is disposed outside the middle nozzle, and a predetermined gap is provided between the middle nozzle and the outer nozzle. In the case of cooling, the outer nozzle is less likely to be deprived of heat by the cooled middle nozzle, and the outer nozzle hardly loses its temperature. Even if warmer gas in the space comes into contact with the outer nozzle surface, the induced gas does not cool down to the dew point, preventing condensation on the outer nozzle surface,
Cost can be reduced by simplifying the heat insulating structure of the outer nozzle. In addition, when the edge of the outer nozzle is separated from the middle nozzle by which the air-conditioning gas is blown out by the gap, the flow state of the induced secondary air changes, and the secondary air flows to the edge of the outer nozzle. It is difficult to adhere to the outer nozzle, and there is no dew condensation, dust adhesion to the outer nozzle edge, generation of mold, and the like. In addition, the air nozzle for blowing air conditioning gas is separated from the ceiling surface or wall surface outside the outer nozzle to reduce sticking of airflow to the ceiling surface or wall surface. The amount of protrusion of the edge of the nozzle from the ceiling surface or wall surface can be reduced, and discomfort with the surroundings can be further reduced.

The conditioned air supplied from the duct 51 enters the middle nozzle 2, passes through the middle nozzle 2, and is blown out from the front end opening on the indoor side into the indoor space. When the high-speed airflow blows out from the middle nozzle 2, the air existing in the gap 4 between the middle nozzle 2 and the outer nozzle 3 is attracted to the room side, and further the gap is divided by the amount of the induced gas. Gas flows into the space 4 from the space inside the ceiling 50, and a gentle airflow toward the room side is generated in the gap 4 (see FIG. 1). Since the middle nozzle 2 and the outer nozzle 3 are thermally separated from each other by the airflow, heat transfer hardly occurs between the middle nozzle 2 and the outer nozzle 3, and the outer nozzle 3 is not cooled to the indoor space without being cooled. Maintain approximately equal temperatures.

Is provided with a gap portion 4 communicating with each of the spaces. When the conditioned air is blown out from the middle nozzle 2 into the indoor space, a gentle airflow is generated in the gap portion 4 toward the indoor side. 3 can be in a state in which heat transfer is difficult to be performed, the temperature of the outer nozzle 3 hardly drops, and dew condensation occurs even when the warmed air in the room in contact with the surface of the outer nozzle 3 comes into contact.

きるという効果を有する。As described above, according to the present invention, the outer nozzle is provided outside the middle nozzle, and a predetermined gap is provided between the middle nozzle and the outer nozzle. In the case of cooling, the outer nozzle is less likely to be deprived of heat by the cooled middle nozzle, and the outer nozzle hardly loses its temperature. Even if warmer gas in the target space for air conditioning comes into contact with the outer nozzle surface, the induced gas does not cool down to the dew point, preventing condensation on the outer nozzle surface and simplifying the heat insulation structure of the outer nozzle. This has the effect of reducing costs. In addition, when the edge of the outer nozzle is separated from the middle nozzle by which the air-conditioning gas is blown out by the gap, the flow state of the induced secondary air changes, and the secondary air flows to the edge of the outer nozzle. This has the effect of preventing dust from adhering to the outer nozzle edge and the occurrence of mold on the outer nozzle edge in addition to dew condensation, preventing contamination of the outlet and its surroundings, and maintaining an aesthetic appearance. In addition, the air nozzle for blowing air conditioning gas is separated from the ceiling surface or wall surface outside the outer nozzle to reduce sticking of airflow to the ceiling surface or wall surface. The protrusion amount of the edge portion of the nozzle from the ceiling surface or the wall surface can be reduced, and there is an effect that the feeling of strangeness with the surroundings can be further reduced.

効果を有する。Further, according to the present invention, the gap between the middle nozzle and the outer nozzle communicates with the space to be air-conditioned and the space in the ceiling or wall, and the air-conditioning gas is supplied from the middle nozzle. When blown out to the air conditioning target space, the gas present in the gap is attracted to the airflow coming out of the middle nozzle,
Further, gas flows from the space in the ceiling or the wall into the gap portion by the amount of the induced gas, and a gentle airflow toward the air conditioning target space side is generated in the gap portion, so that the middle nozzle and the outer nozzle In this state, heat transfer is more difficult to be performed between the nozzles, and in the case of cooling, it is possible to reliably prevent heat from being taken out from the outer nozzle by the cooled middle nozzle, and it is possible to keep the temperature of the outer nozzle substantially at the temperature of the air conditioning target space As a result, dew condensation on the outer nozzle surface can be reliably prevented, heat insulation treatment such as flocking is not required on the surface of the air conditioning target space side including the edge of the outer nozzle, and the appearance of the outer nozzle can be freely set, and the surrounding environment can be set. This has the effect that the aesthetic appearance can be improved by properly harmonizing with the image.

By generating a stronger airflow in the gap, heat transfer between the middle nozzle and the outer nozzle is reliably prevented, and the temperature of the outer nozzle can be maintained at the temperature of the air-conditioned space. Insulation process can be simplified,
This has the effect that the cost can be further reduced and the manufacturing process can be greatly reduced in labor.

に省力化できるという効果を有する。Further, according to the present invention, a pressure difference is generated between the space for air conditioning, in which the gap between the outer nozzle and the middle nozzle communicates with each other, and the space in the ceiling or in the wall. A gas flow having substantially the same temperature as the air-conditioned space is generated in the gap due to the pressure difference between the nozzles, thereby reliably preventing heat transfer between the middle nozzle and the outer nozzle to reduce the temperature of the outer nozzle to the air. The temperature of the space to be conditioned can be maintained, the heat insulation treatment for the outer nozzle can be further simplified, the cost can be further reduced, and the manufacturing process can be significantly reduced in labor.
