Abstract

PURPOSE:To reduce the generation of vibration noise by connecting freely a T-shaped or cross-shaped manifold which is provided with an outside air intake port and exhaust port respectively open to an intake port and an exhaust port provided on the upper part of an airconditioner so that their shape may be selected freely. CONSTITUTION:A large-sized ventilation pipe is designed to form branch pipes 15 and 16 which are T-shaped, U-shaped or cross-shaped. Their respective ends are opened into a plurality of air suction ports 15' and exhaust ports 16'. which are directly connected with an upper air suction port 11 and an exhaust port 12 on an equipment body 1 or with an air suction port 13' and an exhaust port 14' of sound absorbing chambers 13 and 14 and then they are fixed respectively. Care is exerted to their connection method so that the orientation of the air suction port 15' and the exhaust port 16' are freely selected or changed to meet the environment and their positions round the ports. This construction makes it possible to absorb easily the optimum open air in any direction by changing the air suction port 15' on the suction side manifold 15 on one side. Therefore, an airconditioner can be installed even when the space is quite limited. In the case of exhaust air, this construction makes it possible to change a part of vibration noise leaked from the aforesaid exhaust port 16' in any direction by changing the exhaust port 16' of the exhaust side manifold 16 on one side.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is suitable for outdoor installation with the main purpose of suppressing exhaust noise of air conditioners such as heat pump chiller units installed outdoors, preventing raindrops from entering, dispersing exhaust gas, etc. This invention relates to an air intake and exhaust system for a commercial air conditioner.

[Conventional technology]

As a means of supplying heating and cooling indoors, for example, a primary air conditioner such as an air-cooled heat pump chiller unit or a heat pump packaged air conditioner can be installed indoors with a fan coil unit or a secondary air conditioner such as an air handler. The heat pump chiller unit used in the above-mentioned downstream air conditioner was Most of these have the function of sucking air in from the local part of the fuselage and exhausting it from the top, and because they generate particularly loud noises, most of them were installed outdoors.

[Problem to be solved by the invention]

However, as mentioned above, installing a heat pump chiller unit outdoors not only causes a great deal of noise and nuisance to the neighbors, but also rainwater, water, etc. from the outside air intake, exhaust vent, etc. Impurities such as dust were blamed for entering the interior of the machine and causing serious problems with the internal mechanism, and these were also said to be the cause of the failure.

The present invention has focused on these drawbacks and attempts to fundamentally solve the various drawbacks described above by connecting an extremely simple mechanical device described below to a heat pump chiller unit that can be installed outdoors.

[Means to solve the problem]

As a means of solving the above problem, the present invention provides an air conditioner in which an air conditioner such as a blower, a heat exchanger, etc. are arranged inside the air conditioner. An object of the present invention is to provide an air intake/exhaust device for an outdoor air conditioner, characterized in that manifold pipes formed in a T-shape, a cross-shape, etc. with openings are connected in a selectable manner in any direction. .

[Example and operation]

Hereinafter, a heat pump chiller unit exemplifying an embodiment of the present invention will be explained in detail.The heat pump chiller unit is divided into left and right sides by a partition plate (2) inside the airframe (11), and has a heat exchange chamber (3) and a ventilation chamber (3). A U-shaped ventilation passageway (5) forming a chamber (4) is provided, and a heat exchange coil (6), an air blower (7), an electric motor (8), and a compressor (9) are installed in each of the chambers.
), a silencing mechanism al, and other various mechanical devices are arranged.

In addition, there is an intake port 0υ opened at the top of the aircraft body (1), an intake-side silencing chamber (end) equipped with an internal silencing mechanism (not shown), and an exhaust-side silencing chamber (
(b) are arranged in series so that they can be removed as necessary.

Next, the intake/exhaust dispersion device is shown in Figures 1 and 2 (2),
(As shown in O, the large diameter ventilation pipe is formed into a T-shaped, U-shaped, or cross-shaped branch pipe 119Ql, and each branch end is connected to a plurality of intake ports a4 and exhaust ports. a4, and directly into the upper air intake port aυ or exhaust port (6) of the above-mentioned body (1), or into the silencing chamber (13Q4).
Connect to the intake and exhaust ports d and αJ and secure them. The above-mentioned connection method is to arbitrarily change and install the one-way positions of the intake port t4 and the exhaust rod ad in order to adapt to the surrounding environment, position, etc.

Incidentally, in FIG. 2, the respective intake and exhaust directions in the intake/exhaust device are indicated by arrows.

In other words, number 11! ! ! In I, outside air is sucked into the fuselage (1) vertically from above and below through one branch pipe opening, heat is exchanged within the fuselage (1), and air is drawn into the fuselage (1) in the vertical direction from one branch pipe α. It sends out more exhaust gas. Furthermore, by forming each of the branch pipes υ and M into a large number of branch pipes as shown in the second diagram (2) (2), exhaust can be simultaneously performed in multiple directions such as up and down and forward. be.

Although the above shows an example of a heat pump chiller unit for outdoor installation, it is not limited to outdoor use, and can be widely used for outdoor air conditioners etc. depending on the installation location. It can be done.

〔Effect of the invention〕

As described above, the present invention has an air intake and an exhaust port a-yu which are opened in the upper part of the fuselage (1), and an intake port Q9 and an exhaust port α6 at the end of the pipe in the part (2).
Since this is made by connecting manifolds α9Q1e each having an opening, when taking in outside air, the optimum outside air can be drawn from any direction by simply changing the intake port a4 of one of the manifolds I19 on the intake side. can be easily incorporated,
Therefore, the air conditioner can be installed even in a narrow place, and in the case of exhaust, by changing the exhaust port α of one exhaust side manifold θ, the part leaking from the exhaust port α6 can be removed. The noise can be changed in any direction.

Therefore, it completely solves the damage to the surrounding area caused by noise, which was a drawback in the past, and even if there was a risk of leakage, since it is a branch pipe, it is dispersed in multiple directions, significantly reducing the generation of noise. It has the following effects.

Furthermore, by attaching the above-mentioned manifold pipe port 〇Q to the intake and exhaust side silencing chambers (to) and the exhaust port part of αΦ according to claim 0, the generation of noise and vibration inside the fuselage (1) can be suppressed. This makes it possible to more effectively suppress the effects of air pollution, thereby making it possible to easily obtain a low-noise and quiet air conditioner.

Further, as claimed in claim 0, the connection base pipe portions (B) and (G) of the manifold (Ls os) are bent in a slightly downwardly slanted shape, and these are bent in the vertical direction of the fuselage (1). By connecting them, the intake ports a9, υ and the exhaust ports QQ, α6 are vertically oriented, and because they are formed by downwardly sloping connections, they prevent raindrops from entering the inside of the machine. It also has the advantage of reliably preventing breakdowns of various mechanical devices inside the machine due to rainwater.

Moreover, in the present invention, even in the case of countermeasures against oil smoke, which has been a concern in the past, the branch pipe a9αQ filter device can be easily removed or replaced, so oil smoke can be eliminated quickly and easily. Therefore, this invention is most suitable as a device for preventing oil smoke.
