DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an air-cooled absorption type refrigerating apparatus.
BACKGROUND ART
For example, as shown in FIG. 35 through FIG. 38, the prior art air-cooled absorption type refrigerating apparatus is constructed by providing a fan 2 in a center portion of a roughly cubic apparatus main body (main body housing) 1, forming air inlets 3a through 3c on three side walls of the body, providing air-cooled absorbers 4a and 4b and an air-cooled condenser 5 inside the inlets and providing evaporators 6 and 6 above the air-cooled absorbers 4a and 4b.
Then, the air taken in from the air inlets 3a through 3c by the fan 2 is made to pass through the air-cooled absorbers 4a and 4b for the cooling of an absorbent fluid and thereafter blown out upwardly from an air outlet 7 provided on the upper side of the apparatus main body 1 while being changed in direction (refer to. for example, the prior art reference of Japanese Patent Laid-Open Publication No. HEI 1-225868 as a known similar example).
However, the above prior art construction has the following problems.
(1) Since the air intake surfaces are formed in three surface directions of the apparatus main body, there are necessitated air intake spaces outside these three surface directions. As indicated by an imaginary line in FIG. 36, there is necessitated a wide installation space S expanded in four surface directions S.sub.2, S.sub.3 and S.sub.4 including a working space S.sub.1 for maintenance service in addition to the occupation area of the apparatus main body 1 itself.
(2) Since the air stream path extending from the air inlets to the air outlet varies perpendicularly from the horizontal direction to the vertical direction, as shown in FIG. 39, there is a nonuniformity in the flow velocity distribution of the air stream passing through the heat exchangers of the air-cooled absorbers and the air-cooled condenser. This leads to a reduction in the heat exchange performances of the heat exchangers and an increase in draft loss, causing the generation of noises.
SUMMARY AND OBJECTS OF THE INVENTION
The object of the present invention is to provide an air-cooled absorption type refrigerating apparatus capable of solving the aforementioned problems.
In order to achieve the above object, the air-cooled absorption type refrigerating apparatus of the present invention is characterized in that an air inlet is formed in a single surface of an apparatus main body, an air stream path that extends from the air inlet of the single surface to an air outlet that is formed also in a single surface provided in the opposite direction is formed and an air-cooled absorber and an air-cooled condenser are arranged in the air stream path.
Therefore, the air stream path has a form which smoothly continues from the air inlet to the air outlet without perpendicularity, so that the draft loss is reduced to uniform the flow velocity distribution of the air streams of the heat exchangers of the air-cooled absorber and the air-cooled condenser, thereby improving the heat exchange performance and reducing the noises. Then, as compared with the prior art construction in which a plurality of surfaces in different directions of the apparatus main body must be each provided with an air inlet, the present apparatus main body can be formed compact, or in small size. In addition, it is sufficient to provide a relatively small installation space including the air intake space corresponding to the single air inlet surface and the working space necessary for maintenance service, so that the installation space of the apparatus main body can be reduced.
In an embodiment of the present invention, the air outlet is arranged upwardly aslant, and a fan is provided with its fan axis arranged upwardly aslant in correspondence with the air outlet.
Accordingly, with this construction, the stream of air to be blown outward is directed upward, and the installation area on the frontward side can further be reduced.
In an embodiment of the present invention, the air outlet is arr
