Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides an ultra-low-noise air conditioner that fundamentally suppresses the noise generated during air blowing by forming a silencing chamber inside the air conditioner body. It is related to.

[Conventional technology]

In recent years, air conditioning with noise has become a problem, especially in hospitals, hotels, research institutes, etc., and various noise reduction mechanisms have been developed as a means to eliminate it, but all of them are structurally complex, expensive, and difficult to install. difficult,
Furthermore, when the air volume of the air conditioner is large, a complete noise reduction effect cannot be expected.

[Problem to be solved by the invention]

The present invention has been developed in view of the above-mentioned problems, and as a result of research, it has been found that the root cause of noise is particularly severe at the air outlet of the blower. Focusing on the fact that the generated noise can be significantly alleviated and eliminated, we have created a large-capacity silencing chamber in front of the above air outlet to fundamentally eliminate the noise generated during air conditioning, which has been a concern in the past. Its main purpose is to perform suppression and elimination.

[Means to solve the problem]

In order to achieve the above object, the present invention divides the inside of the fuselage 1 into a blower chamber 3 and a heat exchange chamber 4 using a partition plate 2, as shown in the illustrated example. A blower 9 is arranged below, and a heat exchange coil 10 is installed diagonally in the heat exchange chamber 4 adjacent to one side, and a drain pan 14,
Various mechanisms such as the humidifier 17 are disposed, and a sound deadening chamber 11 made of a suitable sound deadening member is provided below the drain pan 14 and in front of the air outlet a of the blower 9 in communication with each other. The aim is to widely provide ultra-low noise air conditioners with the following characteristics.

In addition, the above-mentioned rectifier plate 1 of an appropriate shape is installed in the sound deadening chamber 11.
It is also a consideration to install 3.

[Effect]

The present invention performs the following operations in the above configuration.
The air introduced from the suction port 5 at the top of the fuselage 1 passes through a filter 8, and when the blower 9 is operated, it flows into the adjacent heat exchange chamber 4 through the discharge port a, and the air is heated to an appropriate temperature by the heat exchange coil 10. Heat exchange is carried out, and cold and warm air is blown into each room from the air outlet 6 on one side of the fuselage directly or via a doubt (not shown).

Normally, in such a body, the noise generated by the blower 9 during the air blowing is combined with various noises generated inside the machine, causing noise in the room.

However, in the present invention, a silencing chamber 11 having a silencing mechanism is formed in front of the air outlet a of the blower 9, and in particular, the air is blown in the silencing chamber 11 having a larger capacity than the air outlet a having a small diameter. Because of the flow, the noise generated within the silencing chamber 11 is naturally suppressed, and the current flows naturally and smoothly into the heat exchange chamber 4 through mechanisms such as the rectifying plate 13, and most of the noise is suppressed. It is possible to supply cool and warm air in a quiet manner.

The air blower 9 is placed in communication with the outlet a of the blower 9.

Furthermore, a rectifying plate 13 of an appropriate shape is installed in the air ventilation path 7 at an intermediate portion between the sound deadening box 21 and the heat exchange chamber 4 to rectify the air flow to the heat exchange coil 10.

Fig. 5 shows a case in which the air outlet a is biased to one side and a rectifying plate 13 of a unique shape is installed inside the sound deadening chamber 11, and Fig. 6 shows a part of the shape of the drain pan 14 modified as shown in the example. The one using a drain pan, as shown in Fig. 7, has a specially shaped partition plate 22 between the heat exchange chamber 4 and the silencing chamber 11, and each mechanism ensures and naturally regulates the airflow from the silencing chamber 11. It is said that

Furthermore, due to the installation location, etc., FIG.
