DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-cooled absorption refrigeration apparatus, and more particularly to a structure of an outdoor unit in the refrigeration apparatus.

[0002]

2. Description of the Related Art Air-cooled absorption refrigeration systems and water-cooled absorption refrigeration systems are conventionally known as absorption refrigeration systems. There is a universal problem that heat transfer efficiency is poor, and therefore, an absorber and a condenser in an air-cooled absorption refrigeration system,
When these are compared with those of a water-cooled absorption refrigeration system, the air-cooled absorber or the like must be larger in size than the water-cooled absorber or the like in terms of securing a heat transfer area.

On the other hand, in general refrigeration systems, not limited to absorption refrigeration systems, the occupied space of the refrigeration system itself,
In addition, there has been a strong demand for a reduced installation space including a space for sucking air into the refrigeration apparatus after installation and a service space for maintenance.

In view of such circumstances, for example, Japanese Patent Laid-Open No. 1-22
In Japanese Patent No. 5868, as shown in FIG. 9, an air-cooled absorber 32, which must be large in shape from the viewpoint of securing a heat transfer area, is bent into an “L” shape, and is formed into a rectangular shape. The air-cooled condenser 33 is arranged on the other side of the casing 31 while the air-cooled condenser 33 is arranged on the other side of the casing 31 while the air-cooled condenser 32 and the air-cooled condenser are arranged on the other side of the casing 31. While surrounding with 33,
A fan 35 is disposed in the upper center of a space surrounded by the air-cooled absorber 32 and the air-cooled condenser 33 with its blowing direction directed upward, and suction ports provided on three side surfaces of the casing 31 respectively. The air-cooled absorption type outdoor unit 30 is made compact by reducing the size by sucking air from the air-cooled absorber 32 and passing the air-cooled absorber 32 and the air-cooled condenser 33, respectively, and then blowing the air upward by the fan 35. Has been proposed.

In FIG. 9, reference numeral 34 denotes an evaporator disposed above the air-cooled absorber 32, 36 denotes a low-temperature regenerator disposed above the air-cooled condenser 33, and 37 denotes an air-cooled absorber 32. And a high-temperature regenerator arranged on the opening side of a space surrounded by the air-cooled condenser 33.

[0006] Further, a problem specific to the air-cooled absorption refrigeration system is that the air-cooled absorption refrigeration system partially has a cycle condition exceeding atmospheric pressure. It belongs to "simple boiler" in terms of laws and regulations, and the boiler capacity is subject to legal restrictions, so that a large-capacity refrigeration system cannot be constituted by itself. Therefore,
In order to obtain a refrigeration apparatus having a boiler capacity larger than the legally regulated boiler capacity, it is conceivable to unitize a plurality of refrigeration apparatuses having a boiler capacity not subject to the legal regulation in accordance with the required capacity. Even in the case where a large-capacity refrigeration apparatus is obtained by combining a plurality of small-capacity refrigeration apparatuses to obtain a large-capacity refrigeration apparatus, it is necessary to sufficiently consider the installation space.

[0007]

However, the air-cooled absorption type outdoor unit 30 as in the above-mentioned known example has a rectangular shape, has a "three-sided suction / top-out" structure, and has a remaining one side. Since equipment requiring maintenance such as the high-temperature regenerator 37 is arranged, for example, when this is installed and used alone, as shown in FIG.
It is necessary to provide a suction / service space S of a required width over the entire circumference of the air-cooling absorption type outdoor unit 30, and there is a problem that the installation space cannot be sufficiently reduced.

Further, even when a plurality of air-cooled absorption outdoor units 30 are combined and unitized to obtain a large-capacity refrigeration system, as shown in FIG. 11, each of the air-cooled absorption outdoor units 30, 30,.・ The required suction / service space S is required around the device, and it is not possible to meet the demand for a reduced installation space.

Accordingly, the present invention has been made to provide an air-cooled absorption refrigeration apparatus that can easily reduce the installation space.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be specifically described based on preferred embodiments. FIG. 1 shows an air-cooled absorption outdoor unit X applied to an air conditioner as a preferred embodiment of an air-cooled absorption refrigeration apparatus according to the present invention. The air-cooled absorption type outdoor unit X has the greatest feature in the arrangement and configuration of each component constituting the air-cooled absorption type outdoor unit X, and includes a casing 1 having a substantially long rectangular appearance. Note that the rear surface 1b of the casing 1 (that is, the air-cooling absorption type outdoor unit X)
On the back surface X _1b ) of the suction port 21 over substantially the entire area thereof.
(See FIG. 3), and a suction port 22 (see FIG. 3) is further provided at a lower position of the suction port 21.

An air-cooled absorber 3 is disposed in the casing 1 so as to face the suction port 21, and is located in front of the air-cooled absorber 3 and at a middle position in the vertical direction of the casing 1. The air-cooled condenser 4 is disposed substantially horizontally. The air upstream side of the air-cooled condenser 4 faces the suction port 22. Further, the front 1a (i.e., front X _1a of the air-cooled absorption type outdoor unit X) of the casing 1 to and above the said air-cooled condenser 4 in side,
A pair of left and right fans 7, 7 composed of propeller fans
However, they are arranged in a state where the blowing direction is directed obliquely upward. In this case, the pair of left and right fans 7, 7
Are arranged eccentrically by a predetermined dimension in the longitudinal direction of the casing 1 (see FIG. 5).

In FIG. 1, reference numeral 5 denotes a high-temperature regenerator,
6 is a low-temperature regenerator, 8 is a receiver, 9 is a gas-liquid separator, 10
Denotes a high-temperature solution heat exchanger, 11 denotes a low-temperature solution heat exchanger, and 12 denotes a blower. These devices, the air-cooled absorber 3, the air-cooled condenser 4, and the fans 7,
Is configured.

[0038] In air-cooled absorption type outdoor unit X of such a configuration, by the fans 7, 7 is operated, the air-cooled absorber 3 so that the air sucked from the suction port 21 is indicated by air flow A ₁ absorbing liquid and the heat exchange in the air-cooling the absorber 3 as it passes through, also the air-cooling condenser when passing through the air-cooled condenser 4 so that air sucked from the suction port 22 is indicated by air flow a ₂ Heat exchange with the primary refrigerant in 4 is performed. Then, air that has passed through these air-cooled absorber 3 and the air-cooled condenser 4 is then merged as shown by the airflow A ₃ blown out obliquely upward from the fans 7, 7.

The capacity of the air-cooled absorption type outdoor unit X is set so as to belong to the capacity range of a “simple boiler” which is not subject to legal restrictions in the “Boiler and Pressure Vessel Safety Rules”.

As described above, the air-cooled absorption type outdoor unit X has the above-described suction ports 21 and 22 connected to the casing 1.
Is formed only on the rear surface 1b side of the casing 1 and maintenance of each device in the casing 1 is possible from the rear surface 1b side. Therefore, as shown in FIG. What is necessary is just to secure on the back 1b side. Therefore, the installation space of the air-cooled absorption type outdoor unit X is made smaller than that in the case where it is necessary to secure the suction / service space S on the entire circumference as in the above-mentioned known example (reduction of the installation space). ) Will be promoted.

On the other hand, since the capacity of the air-cooled absorption outdoor unit X is within the legally regulated range as described above, it can be used alone. A plurality of Xs can be installed in parallel to form a unit, and a large-capacity air-cooled absorption refrigeration system exceeding the legally regulated range can be obtained. Hereinafter, the configuration and the like in the case of the multiple installation will be described.

FIGS. 2 and 3 show a pair of refrigerator modules X ₁ and X having the same structure as the air-cooled absorption type outdoor unit X.
_2, front surface 1a of the casing 1, 1a (i.e., refrigerator module X _1, X ₂ of the front X _1a, front X _1a) with is closely opposed to each other, the outdoor unit by integrating these by the connection frame 15 This shows a case where the unit Z is configured. In the outdoor unit Z, when the fans 7, 7 of each chiller module X _1, X ₂ is operated, respectively, as indicated by the airflow A _3, A _3, each of the refrigerating machine module X ₁ , fan 7,7 X _2, blowing air is blown obliquely upward respectively from the same 7,7. In this case, the respective fans 7 of the respective refrigerator modules X ₁ and X ₂ ,

Of the blowing air blown out from the fan 7 and 7, the other of the refrigerator module X ₂ interference with blowing air blown out from the fan 7, 7, and the outlet air and the other from one of the refrigerator module X ₁ each outlet air of the refrigerator module X ₂ is the generation of short-circuit to be sucked into the other of the refrigerator module X ₂ or one chiller module X ₁ side is prevented as much as possible. However, in this embodiment, in order to further prevent the mutual interference of the blown-out air and the occurrence of the short circuit as described above, these portions are provided on the opposing portions of the refrigerator modules X ₁ and X _2. A wind direction guide member 16 for partitioning the two is arranged upright, and blown air blown obliquely upward from each of the refrigerator modules X ₁ and X ₂ is forced upward by the wind direction guide member 16. To be deflected.

It is sufficient to provide the service space S, for example, when it is necessary to secure a suction / service space all around the plurality of refrigeration systems as in the case of arranging a plurality of refrigeration systems of the above-mentioned known examples and unitizing them. In comparison with the above, the installation space can be reduced, and the range of application of a large-capacity refrigeration system can be expected.

Further, by setting each of the refrigerator modules X ₁ and X ₂ to a capacity that is not subject to legal restrictions, the capacity of each of the refrigerator modules X ₁ and X ₂ is originally restricted to legal restrictions. Such a large-capacity refrigeration apparatus can be obtained within legal regulations, and it is easy to cope with diversification of the capacity of the outdoor unit Z as a product and to form a series.

Further, a small-capacity refrigerator module X ₁ ,
Since a combination of X ₂ constitutes a outdoor unit Z of large capacity, it is possible to perform the capacity control of the mass as a whole and each capacity control refrigerator module X _1, X ₂ of small volume, e.g. Compared to a single-unit, large-capacity outdoor unit that is controlled in capacity, the capacity control is easier and the operation control can be simplified accordingly.

Further, since the outdoor unit Z is constituted by the pair of refrigerator modules X ₁ and X ₂ , for example, if one of the refrigerator modules X ₁ fails, the other refrigerator module X _{1 and} X ₂ become faulty. machine module X ₂ only continuous operation at are possible, as compared with the case stop forced operation itself of the refrigeration system by the failure such as when the refrigeration apparatus having a large volume of unitary construction, The risk distribution for the failure can be performed, and the operational reliability of the outdoor unit Z is improved accordingly.

FIG. 7 shows four refrigerator modules X ₁ , X ₂ , X ₃ , and X having the same structure as the air-cooled absorption type outdoor unit X as an example of the development of the outdoor unit Z shown in FIG. ₄ is divided into two sets, and a pair of refrigerator modules X ₁ , X ₂ and X ₃ , X ₄ belonging to each set are arranged with their front surfaces being close to each other, and the air-cooling absorption type outdoor unit is provided. The figure shows an outdoor unit Z having a capacity four times that of the case where X alone is installed. Also in this case, the outdoor unit Z including only the pair of refrigerator modules X ₁ and X _2.
As a matter of course, the same operation and effect as described above can be obtained.

FIG. 4 shows a pair of refrigerator modules X ₁ , X ₂ having the same structure as the air-cooled absorption type outdoor unit X, and the rear surfaces 1 b, 1 b of the casings 1, 1 (that is, the refrigerator module X). The outdoor unit Z is configured such that the back surfaces X _1b , X _2b of X ₁ , X ₂ are turned back at predetermined intervals. In this case, FIG. 8 shows an outdoor unit Z having four refrigerator modules X ₁ , X ₂ , X ₃ , and X _4. As shown in the figure, only the capacity is different from that provided with the machine modules X ₁ and X _2, and the operational effects that can be achieved are the same.
Each of the refrigerating machine module X _1, may be ensured shareable suction service spaces S on both the back direction portion of X _2, for example, a refrigerator module X _1, X ₂ as shown in FIG. 6 or FIG. 7 The size of the suction / service space S to be ensured is １ ／ of that in the case of the opposed arrangement, so that the installation space can be further narrowed.
