Air-cooled absorption type refrigerating plant

Abstract

In an air-cooled two-stage absorption type refrigerating plant, a plant main body (1) is provided in its longitudinal middle with a machine chamber (2) having a high-temperature regenerator (G2), a low-temperature regenerator (G1) and a heating-purpose heat exchanger (B). The machine chamber (2) is provided on its longitudinal opposite sides with air-cooled heat exchange sections (3, 3) each having an air-cooled heat exchange unit (X) consisting of air-cooled absorbers (A, A), an air-cooled condenser (C) disposed between the lower ends of the air-cooled absorbers (A, A) and fans (F) disposed in the upper region between the air-cooled absorbers (A, A), and an evaporator (E) disposed substantially in the middle between the air-cooled absorbers (A, A). As a result, the air-cooled heat exchange sections (3, 3) are positioned on opposite sides of the machine chamber (2).

Description

technical field [0001] The invention relates to an air-cooled absorption refrigeration device. Background technique [0002] The conventional air-cooled absorption refrigeration device is formed by forming an air suction port on three sides of a cube-shaped device body. In order to make it correspond to it, two air-cooled absorbers and an air-cooled condenser are arranged, and an air-cooled condenser is placed above the center. It is constructed by installing a fan. With this configuration, the heat transfer area of ​​the air-cooled absorber and the air-cooled condenser is ensured as large as possible (for example, refer to JP-A-1-225868). [0003] In addition, in the case of the air-cooled absorption refrigeration device with the above-mentioned structure, the air sucked in by the fan from the air inlet formed on three sides passes through the air-cooled absorber and the air-cooled condenser, effectively cooling the absorption liquid and the refrigerant vapor.

AI Technical Summary

Problems solved by technology

[0005] However, in the case of the air-cooled absorption refrigerating apparatus of the above-mentioned well-known example, since the air suction port is formed on three sides, the remaining one side has to be used as a maintenance space.

As a result, if a plurality of units are connected to achieve a large amount of refrigeration, it becomes difficult to secure maintenance space and suction space for the air suction port.

[0006] In addition, in order to obtain a large cooling capacity of the refrigeration device, if the method of enlarging the heat dissipation area of ​​the air-cooled absorber and the air-cooled condenser is adopted, there will be a problem of increasing the size of the device body.
