[0030] Refer to the attached figure 1 with figure 2 , the first embodiment of the present invention will be described.

[0031] exist figure 1 In , the overall structure of the absorption refrigerator equipped with the high-temperature heat accumulator related to this embodiment is schematically described.

[0032] exist figure 1 Among them, 1 is the evaporator absorber shell (lower shell), and the evaporator 2 and the absorber 3 are accommodated on the lower shell 1. 4 is the high-temperature heat storage device related to this embodiment, equipped with a burner 5. In the middle of the lean absorption liquid flow pipe 6 from the absorber 3 to the high temperature heat storage 4, an absorption liquid pump P, a low temperature heat exchanger 7 and a high temperature heat exchanger 8 are arranged.

[0033]10 is an upper casing, and a low-temperature heat storage device 11 and a condenser 12 are housed in the upper casing 10 . Moreover, 13 is a refrigerant steam pipe arran...

[0053] Refer to the attached image 3 A second embodiment of the present invention will be described. Components having the same functions as those described in the preceding drawings are denoted by the same reference numerals, and the corresponding descriptions are omitted within the scope not to hinder the understanding of the present invention (the same applies to the embodiments described later).

[0054] In the aforementioned first embodiment, the liquid inlet 47 is arranged above the middle of the last tube row of several parallel tube rows of the third liquid tube group 37C (see figure 2 (A)), and in the second embodiment as image 3 As shown, it is arranged on the upper part of the left and right sides of the position on the opposite side of the burner 5 in the kettle wall 41 . In other words, the pipes constituting the liquid inlet 47 may be branched to the left and right, and dilute absorption liquid may be dispersed from the upper parts of the side portions 41C o...

no. 3 approach

[0057] Refer to the attached Figure 4 A third embodiment of the present invention will be described.

[0058] In the foregoing second embodiment, the opening position of the manifold 48 of the pipe constituting the liquid inlet 47 is as follows: image 3 As mentioned above, the position of the opening is at the last tube row position of the several parallel tube rows of the third liquid tube group 37C in the flow direction of the combustion gas, and in the direction at right angles to the flow direction of the combustion gas, that is, in the left and right direction. At the position of the side portion 41C of the kettle wall 41 .

[0059] However, as in the third embodiment Figure 4 As shown, make the pipe manifold 48 that constitutes the liquid inlet 47 on a plane (see Figure 4 (A)) is bent into a U shape, and extends along the upper part of the side part 41C of the left and right sides of the kettle wall 41, and is distributed with dilute absorption liquid in the longi...

Abstract

In a high-temperature regenerator which has vertical liquid pipe groups in the proximity of which a combustion flame and combustion gas from a burner pass and a double can wall which communicates with upper and lower portions of liquid pipes forming the vertical liquid pipe groups and is arranged at a position of a furnace wall and which heats and concentrates a diluted absorption solution passing through the vertical liquid pipe groups and the double can wall, a solution inlet for sprinkling the diluted absorption solution in an open state is provided above liquid pipes arranged on a side opposite to the burner.

Description

technical field [0001] The invention relates to the construction of high temperature heat storage for absorption refrigerators. Background technique [0002] The high-temperature heat accumulator installed on the absorption chiller (including devices called absorption cold and hot water machines, etc.) occupies a relatively large proportion of weight and volume in the overall absorption chiller. Therefore, in order to reduce the overall size of the absorption refrigerating machine, it is necessary to reduce the size of the high-temperature heat accumulator. Moreover, from the perspective of environmental protection, the high temperature heat storage should also achieve low NO X change. [0003] However, although most of the original high-temperature heat storage devices adopt the furnace smoke tube method or the furnace liquid pipe method, it is impossible to remove the combustion chamber as the furnace drum due to the use of these two high-temperature heat storage devices...
