Abstract

PURPOSE:To conduct the air-conditioning and ventilation of a room without using fans, recirculation ducts and the like by drawing in the air of the room by means of a nozzle having an ejector effect in blowing off the conditioned air by recirculating the mixture of the conditioned air and air of the room. CONSTITUTION:A nozzle 13 is constituted in such a manner as to extend in the axial direction of an aircraft in the passenger cabin, to blow off a regulating air into an air passageway 12, and to obtain an ejector effect drawing in the air of the passenger cabin from a space provided between the nozzle 13 and the inner wall panel 11 of the aircraft. When the regulating air is therefore blown off into the passageway 12 from the nozzle 13 through an air supply duct 2 from an air conditioner 1, the air of the passenger cabin is drawn into the air passageway 12 by the ejector effect. The mixture of the conditioned air in the passageway 12 and a blown air is blown off to the passenger cabin from the upper air passageway 12, the air-conditioning and ventilation being carried out. On the other hand, a part of the air in the passenger cabin is discharged to the underneath the floor from an exhaust port 4, and is discharged from an disused louver 6 through an outflow valve 5 to the atmosphere.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air conditioner applied to aircraft, automobiles, railway vehicles, ships, buildings, and the like.

[Conventional technology]

A conventional air conditioner for an aircraft will be explained with reference to FIGS. 4 to 6.

In the apparatus shown in FIGS. 4 and 5, the empty UR11 unit O1
The conditioned air whose temperature has been adjusted is guided into the machine through the air supply duct 02, and is blown out from the air outlet o3. This conditioned air is heated and ventilated inside the aircraft, and then
4 to below the floor 09, a part of which is guided by a fan 010 through a recirculation duct 07 to an air supply duct 02, where it is mixed with conditioned air and used again for heating and cooling ventilation inside the aircraft. The remainder of the air that has flowed from the exhaust port 04 to the underfloor area passes through the outflow valve 05 and is discharged from the exhaust looper 06 to the outside of the machine.

In the device shown in FIG. 6, an air supply manifold 08 is attached to the lower end of an in-machine wall baffle 011 having an air passage 012 on the back side, and the conditioned air flows through the air passage 012 on the back side of the in-machine wall panel 011, and After the panel 011 is heated and cooled, it flows out into the machine from the air outlet 03 at the upper end.

[Problems to be Solved by the Invention] The conventional devices shown in Figure 4 and Part 5 perform heating and cooling simply by blowing out conditioned air into the cabin. In this case, there is a large temperature difference between the conditioned air temperature, the cabin cabin temperature, and the interior panel temperature, which impairs passenger comfort. Additionally, the conventional device shown in Figure 6, which requires a special duct and fan in the recirculation system, solves the problem associated with the temperature difference described above, but requires a special duct and fan in the recirculation system. Nothing will change.

The present invention aims to solve the above-mentioned problems of conventional air conditioners for aircraft and the like.

[Means to solve the problem]

The air conditioner of the present invention includes an inner wall panel having an air passage formed on the back side, and an ejector effect provided at one end of the air passage to blow out conditioned air into the air passage and suck indoor air. It includes a nozzle and an air outlet provided at the other end of the air passage.

[Function] By providing a nozzle with an ejector effect at one end of the air passage formed on the back of the inner wall panel, when the conditioned air is blown out from the nozzle, indoor air is attracted and sucked into the air passage. Since indoor air is recirculated by mixing with the conditioned air blown out from the nozzle, there is no need for a special recirculation system such as a fan or recirculation duct.

In addition, since the mixed air of indoor air and conditioned air passes through the air passage on the back of the inner wall panel, heat exchange occurs between the inner wall panel and the mixed air, and the inner wall panel acts as a heat transfer surface. This contributes to indoor heating and cooling. Therefore, the temperature difference between the surface temperature of the inner wall panel, the indoor temperature, and the blown air temperature is reduced, and indoor comfort is improved.

[Example] An example of the present invention will be described with reference to FIGS. 1 to 3. 1 is the air space 1liil provided in the rear of the aircraft fuselage.
It is a small vessel. An air passage 12 is formed on the back side of the interior wall panel 11 in the aircraft cabin, and at the lower end of the air passage 12 there is a nozzle through which conditioned air from the air conditioner 1 is supplied via the air supply duct 2. 13 are provided. As shown in FIG. 2, the nozzle 13 extends inside the cabin in the axial direction of the aircraft, blows out conditioned air into the air passage 12, and
The nozzle 13 is configured to have an ejector effect of blowing air inside the cabin through a gap provided between the nozzle 13 and the interior wall panel 11. At the upper end of the air passage 12, an air outlet 3 is formed into the passenger compartment. Furthermore, a plurality of exhaust ports 4 leading to the underfloor are provided on both sides of the floor 50, and the air exiting the exhaust ports 4 is discharged outside the aircraft from an exhaust halo provided on the nose side of the aircraft via an outflow valve 5. It looks like this. Note that arrows in the figure indicate air flows.

In this embodiment, conditioned air is blown out from the air conditioner l through the air supply duct 2 and into the air passage 12 from the nozzle 13, and at this time, the air in the cabin is sucked into the air passage 12 by the ejector effect. . The mixed air of the conditioned air in the air passage 12 and the blown air is blown out from the upper end of the air passage 12 into the cabin, and air conditioning, heating, and ventilation are performed.

A part of the air in the cabin is exhausted from the exhaust port 4 to the floor below.
It passes through the outflow valve 5 and is discharged from the exhaust halo to the outside of the machine.

In this way, in this embodiment, the air in the cabin is blown into the air passage 12 as the conditioned air is blown out from the nozzle 13, and this air is recirculated into the cabin.
The cabin can be heated, cooled, and ventilated without the need for recirculation ducts.

Furthermore, since the mixed air of the above-mentioned conditioned air and the air sucked into the cabin flows through the air passage 12 on the back of the in-flight wall panel 11, heat exchange takes place between the in-flight wall panel 11 and the mixed air. The interior wall panel 11 acts as a heat transfer surface and contributes to heating and cooling the cabin.

This reduces the temperature difference between the surface temperature of the interior wall panel 11, the temperature inside the cabin, and the temperature of the blown air, improving passenger comfort.

[Effects of the Invention] The present invention uses a nozzle with an ejector effect to suck in indoor air when blowing out conditioned air, and recirculates the mixed air of conditioned air and indoor air into the room. It is possible to heat, cool, and ventilate the room without using any equipment. Further, the inner wall panel exchanges heat with the mixed air of the conditioned air in the air passage on the back side and the indoor air blown in, and the inner wall panel acts as a heat transfer surface and contributes to heating and cooling the room. As a result, the temperature difference between the surface temperature of the inner wall panel, the room temperature, and the blown air temperature can be reduced, and comfort can be improved.
