Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to generators and other main body equipment, and main body control equipment [
This invention relates to improvements in absorption refrigerators, absorption heat pumps, and absorption chiller-heating machines (hereinafter referred to as "absorption refrigerators of this type"), which are constructed by surrounding an exterior panel with an exterior panel.

(B) Conventional technology The conventional technology for this type of absorption refrigerator is to surround the generator, absorber, refrigerator main unit equipment, and refrigerator control equipment (electrical equipment) such as the in-flight control panel with an exterior panel. A small absorption chiller/heater made by
Air Conditioning Equipment Handbook 2”, P513-P525,
[Refer to May 21, 1980, published by Sanyo Electric Air Conditioning Equipment Co., Ltd.] is known.

(c) Problems to be Solved by the Invention The above-mentioned conventional small-sized absorption chiller/heater has the advantage that even if it is installed outdoors, the refrigerator main unit equipment and the in-machine control panel are not exposed to wind and rain. However, it has the disadvantage that the high-temperature thermal power used in the generator is likely to be trapped inside the exterior panel and damage the electrical components of the in-flight control panel. In order to eliminate this drawback as much as possible, it is conceivable to place the in-machine control panel in the lower part of the exterior panel where heat does not accumulate and is far away from the generator. There are various problems such as being limited to a narrow space, making it difficult to install and operate the in-flight control panel, and making it easy for rain and dew to penetrate from above the exterior panel and enter the inside of the in-flight control panel. are doing.

In view of these problems, the present invention provides an absorption refrigerating machine of this type, which has a large degree of freedom in the placement of refrigerator control equipment such as an in-flight control panel, and can reduce damage to the refrigerator control equipment. The purpose is to

B) Means for Solving the Problems The present invention, as a means for solving the above problems, arranges the air inlet of the blower used for the generator burner at the top and arranges the ventilation port at the bottom of the exterior panel. to form a passage for air to flow from bottom to top in the space within the panel, and
This type of absorption refrigerator is constructed by arranging refrigerator control equipment (electrical equipment) and/or equipment for the refrigerator main body in the middle of this passage.

(E) Function This type of absorption refrigerator according to the present invention exhibits a function (function) of forcibly sucking the heat emitted from the refrigerator body equipment into the blower together with the air. This action eliminates heat buildup in the space inside the exterior panel and prevents excessive temperature rise in the space, so no matter which space the refrigerator control equipment is placed in, the equipment Damage to electrical components such as circuits is reduced. Furthermore, since the temperature of the air supplied to the burner is increased, the operating efficiency (thermal efficiency) of this type of absorption refrigerator is also improved.

(F) Embodiment FIG. 1 is a schematic structural diagram showing an embodiment of this type of absorption refrigerator according to the present invention. In Figure 1, (1)

t), space (A)Ic forms passages (R1) and (R1) for air flowing from bottom to top, and this passage (R1)
Refrigerator control equipment ([01 is placed in the middle, and
Equipment for the refrigerator main body is arranged in the middle of the passage (R7).

In addition, α1) is an air circulation duct formed so as to surround most of the chimney (9), and (1) is a bellows-shaped air introduction hose that connects the duct housing 1 and the blower of the burner (B). It is.

Absorption chiller configured in this way (hereinafter referred to as this machine)
In the case of VC oil, from the vents (Ets) and (Bit) to the exterior panel (Pl, Italy)...inner space (Al K It flows and is sucked into the air intake port (Eout).Then,
The heat released from the generators f1+, (3), solution heat exchangers (7), (8), or equipment for the refrigerator main body, such as piping, is transferred to the passage by the suction force of the blower (not shown) of the burner (B). It is forcibly carried to the burner (Bl) together with the air flowing through (R2).For this reason, in this machine, the space [
Particularly in the upper space], heat does not accumulate in the upper space and the temperature rises excessively (the inside of the path (R+) is maintained at a temperature close to the outside temperature. Therefore, in this machine, the refrigerator control equipment (10) The electrical components of the device are hardly damaged by heat, and their performance can be maintained well over a long period of time.

In addition, in this machine, the temperature of the air supplied to the burner (Bl) is raised by the heat radiation of the refrigerator main unit equipment and the heat radiation of the chimney (9), so the combustion efficiency of the burner (Bl) and the high temperature generator (1 ) can improve the thermal efficiency of the machine, which in turn can improve the operating efficiency of the machine.
