(Field of Industrial Application) The present invention relates to an air conditioning hose for sending air conditioning air from air conditioning equipment installed in an airport to parked aircraft. (Prior Art) Generally, the engine and auxiliary power unit of an aircraft are turned off while the aircraft is parked after landing, so it is not possible to use the air conditioning equipment installed in the aircraft that receives power from them. Therefore, while the aircraft is parked, the air conditioning equipment installed in the airport is activated and the air conditioned air is sent into the aircraft through an air conditioning hose to maintain the air conditioning inside the aircraft in a comfortable state. I try to do that. In this case, the work of supplying air conditioning air (cooling and heating air) to parked aircraft is first carried out at a narrow PIT6, as shown in Figure 2, which is buried in a specific area within the airport where the aircraft approaches. An aircraft parked next to an aircraft where a worker is dragging an air conditioning hose across concrete in order to take out an air conditioning hose stored inside and connect the end to a supply port on a distant aircraft. The vehicle was quickly transported to the aircraft while taking a detour so as not to disturb the departure preparation vehicles and the workers in the vicinity. After connecting the air conditioning hose to the aircraft, the air conditioning equipment was activated and the air conditioning Commercial air (cooling and heating air) is sent to the aircraft via air conditioning hoses. Furthermore, after the supply work is completed, the air conditioning hose is immediately stored in the PIT 6 by reversing the process described above. The above-mentioned work of supplying air conditioning air (cooling/heating air) and storing the air conditioning hose in PIT6 is carried out 10 times a day.
It is done frequently, about once. (Problem that the invention attempts to solve) However, conventional hoses for aircraft air conditioning,
Because they were made of fabrics mainly made of nylon, Tetron, etc. coated with rubber or vinyl, they deteriorated when exposed to the hot sun or direct sunlight, and the heat loss of the air conditioning air, which is the internal air conditioning air, was large. There was a problem that the air blowing efficiency was not good. In addition, even if a hose were made from existing insulating fabrics, it would be extremely heavy compared to conventional air conditioning hoses, making it inconvenient to handle and store, and having poor durability, flexibility, and elasticity. There is a problem. The present invention aims to solve the above problems. (Means for Solving the Problems) The present invention achieves the above object, and includes a surface fabric in which a heat-resistant and durable fabric is coated with the same kind of heat-reflective coating, and a heat-resistant, durable fabric. durability,
It is made by sandwiching a flexible foam insulation material between a stretchable inner fabric and heat-vulcanizing it with a thermosetting adhesive. (Function) The present invention has the above configuration, and according to this, the outer layer of the air conditioning hose is made of a surface fabric made of a heat-resistant and durable fabric with the same type of heat-reflective coating formed thereon. With this structure, direct sunlight can be reflected under the scorching sun, and deterioration of the hose due to direct sunlight can be prevented. In addition, since the middle layer of the air conditioning hose is made of an insulating material made of flexible foam, it is lightweight, easy to handle and store, and the loss of heat from the air inside the air conditioner is reduced. The air blowing efficiency is improved, and it is also possible to reduce the capacity of air conditioning equipment. (Example) Fig. 1 shows an example of the implementation of the present invention.
A heat insulating material 1c made of foamed urethane is sandwiched between the inner fabric 1b made of knitted nylon fibers and a highly elastic inner fabric 1b, and heat vulcanized with a thermosetting adhesive 1d. As shown in FIG. 2, the air conditioning hose 1 has both ends connected to the tip opening 2a of a buried pipe 2 that connects to air conditioning equipment installed in the airport, and an air conditioning air supply coupler that connects to an air conditioning duct in the aircraft body 3. 4 by a band 5, and is used to send air conditioning air from the air conditioning equipment into the aircraft body 3. Tables 1 to 3 show the results of a comparison experiment conducted by the inventor of the present application with a conventional hose and the inventor's hose during cooling by air conditioning equipment installed in an airport, and according to the results, When the same amount of cold air is supplied to the hose at approximately the same temperature, the temperature difference between the inlet and outlet of the hose is 6.
℃, while the hose of the present invention has a temperature of just over 3℃.The hose of the present invention clearly has less heat loss and can send cold air at a lower temperature. It can be seen that the hose has better insulation efficiency in air supply. In addition, the weight of the conventional hose fabric is approximately 670g/m 2
In contrast, the hose of this invention has a weight of about 400 g/m 2
It was found that the hose of the present invention is clearly lighter and easier to handle. Furthermore, it was found that the pressure resistance of the hose was the same between the conventional hose and the hose of the present invention. (Conditions) Outside temperature 33℃ Outside humidity 56%

Note that both ends of the air conditioning hose 1 of the above embodiment are machine sewn, and a spiral 8 containing a steel wire 7 is spirally wound around the outer circumferential surface of the hose 1 except for the machine-sewn parts as shown in FIG. If you turn it and sew it on, you can make it even stronger. The air conditioning hose 1 having such a configuration is shown in FIGS. 3A, B,
As shown in C, the tip was narrowed and a spiral 8 containing steel wire 7 was sewn along the entire length, and the tip was narrowed and a spiral 8 containing steel wire 7 was sewn on both ends. Three types were prepared: one without a constricted part, and one with a spiral 8 of steel wire 7 sewn over the entire length. (Effect of the invention) As described above, according to the invention, the outer layer of the aircraft air conditioning hose is made of a surface fabric made of a heat-resistant and durable fabric with the same type of heat-reflective coating formed thereon. Therefore, it has the effect of preventing the hose from deteriorating due to direct sunlight. Furthermore, since a heat insulating material is interposed between the outer layer and the inner layer of the hose for aircraft air conditioning, heat loss is reduced compared to the conventional hose, and the efficiency of blowing air for cooling and heating is improved. Furthermore, since the aircraft air conditioning hose has a special three-layer structure, it has excellent heat resistance, durability, flexibility, and elasticity.
