Abstract

PURPOSE: To reduce the amount of leakage of refrigerant from the whole flexible hose and the amount of its diffusion to the air by loosely inserting an inner hose used as a passageway for a high-pressure fluid into an outer hose used as a passageway for a low-pressure fluid. CONSTITUTION: A flexible hose 1 has a concentric double-tube structure comprising an outer hose 1a that is made of rubber and is used as a passageway for a low-pressure fluid (arrow A); and inner hose 1b that is made of rubber and is loosely inserted in the outer hose 1a to act as a passageway for a high- pressure fluid (arrow B). The outer hose 1a may be a bellows hose made of a metal. As a consequence, the amount of the leakage from the whole hose can be reduced to an extremely low level since the contact area between the flexible hose and the air is small and the inner hose as the passageway for the high-pressure fluid with a greater leakage amount is surrounded by the inner hose as the passageway for the low-pressure fluid with a less leakage amount.

(Prior technology) In automotive air conditioners, 7 lexiple hoses are used to connect the compressor fixed to the engine and the condenser and cooling unit attached to the vehicle body. Engine vibrations are transmitted from the compressor to the condenser. This prevents p from being transmitted to the cooling unit.

Conventionally, rubber hoses have not been used as 2-7 lexiple hoses, but rubber hoses are easily permeable to 7 leon (trade name of DuPont) gas used as a refrigerant in air conditioners, so they are used only once every few years. It was necessary to replenish the 7 Leon refrigerant, and there was a risk that the 7 Leon refrigerant that passed through the rubber hose would diffuse into the atmosphere and pollute the atmosphere.

(Means for solving the problem) The present invention provides that the amount of refrigerant leaking from the 7 lexiple hose is
The higher the temperature and pressure of the refrigerant flowing through the compressor, the greater the amount of refrigerant.High-temperature, high-pressure refrigerant flows through the 7 Lexipul hose connected to the compressor's discharge port, while low-temperature, low-pressure refrigerant flows through the 7 Lexipul hose connected to the suction port. This was done by focusing on the flow of refrigerant.

(Function) According to the present invention, since the 7 lexiple hose has a double W structure consisting of an outer hose and an inner hose, the contact area between the hose and the atmosphere is reduced, and the inner hose is used for high-pressure fluid with a large leakage amount. Since the outer hose is a passage for low-pressure fluid with a relatively small amount of leakage, the amount of refrigerant leaking from the entire flexible hose and the amount of diffusion into the atmosphere are extremely small.

The automobile air conditioner to which this embodiment is applied has the above configuration, and the refrigerant that has been compressed by the compressor 5 to become a high-temperature, high-pressure gas flows from the discharge port of the compressor 5 to the inner hose 1b.
The liquid is then sent to the condenser 6 through the inner cylindrical portion 2b, where it is cooled to a condensation point and reduced to a high-temperature, high-pressure liquid. The refrigerant reduced to high temperature and high pressure liquid is passed through metal pipe 8,
It passes through the receiver 9 and is sent to a cooling unit (not shown), where it becomes a low-temperature, low-pressure mist due to the action of an expansion valve, absorbs heat from the surroundings in the cooling unit, and becomes a low-temperature, low-pressure gas. Then, the refrigerant, which has become a low-temperature, low-pressure gas, flows from the cooling unit to the metal pipe 7 and the outer hose la,

The vibrations of the compressor 5, which is fixed to the ennon, are absorbed by the 7 lexiple hose 1 and are prevented from being transmitted to the condenser 6 and the cooling unit. Conventionally, two flexible hoses were used, one connecting the discharge port of the compressor 5 and the condenser 6, and the other connecting the suction port of the compressor 5 and the cooling unit, but according to this embodiment, one flexible hose is used. Since the pull hose 1 is sufficient, the contact area of the 7 lexi pull hose 1 with the atmosphere is reduced, and moreover, the high temperature, high pressure refrigerant with a large permeation rate from the 7 lexi pull hose 1 passes through the inner hose 1b, and the low temperature, low pressure refrigerant with a low permeation rate is transferred from the 7 lexi pull hose 1. Since the refrigerant passes through the outer hose 1a, the amount of refrigerant leaking as a whole is extremely small.

According to this embodiment, a high-strength rubber hose is used for the inner hose 1b, which serves as a passage for high-temperature and high-pressure refrigerant, and a metal bellows-shaped hose is used for outer hose 1°a, which serves as a passage for low-pressure refrigerant. By using this method, refrigerant leakage can be completely eliminated, and the metal bellows type hose, which has weak axial strength, is reinforced by the rubber inner hose 1b. 6 By nature, metal bellows type hoses are weak against internal pressure. However, according to the present invention, the outer hose l'a using a metal bellows type hose is used as a passage for low pressure refrigerant, so even a metal bellows type hose can be used satisfactorily.

According to this embodiment, it is possible to completely eliminate refrigerant leakage, and there are also advantages such as extremely easy installation of the flexible hose 1.6 (Effects of the Invention) According to the present invention, low pressure By loosely inserting the inner hose, which is used as a high-pressure fluid passage, into the outer hose, which is used as a passage for high-pressure fluid, the
Since it is made of T construction, the contact area between the flexible hose and the atmosphere is reduced, and the inner hose serves as a passage for high-pressure fluid with a large amount of leakage.The outer hose serves as a passage for low-pressure fluid with a small amount of leakage. The amount of fluid leaking becomes extremely small, and diffusion into the atmosphere can be suppressed. In particular, if the present invention is applied to a 7-leak pull hose for an automobile air conditioner, air pollution caused by 7-leon gas can be prevented, and there is no need for frequent replenishment, which is economical.
