効率の向上が図れる。 Most of the conventional absorption air conditioners of this type use a water-lithium bromide solution, and this cycle is as shown in FIG. That is, a regenerator 2 is provided which separates a dilute solution into a concentrated solution and refrigerant vapor using a burner 1.
A condenser 3 is connected to the regenerator 2 to condense the separated refrigerant vapor into liquid refrigerant. The liquid refrigerant obtained by the condenser 3 is sent to the evaporator 5 via the pressure reducing valve 4A, where it exchanges heat with the atmosphere to remove latent heat of vaporization from the atmosphere, thereby performing a cooling effect. An absorber 6 is connected to the evaporator 5, and a dilute solution obtained by absorbing the refrigerant vapor in the evaporator 5 is sent to the absorber 6 through a solution circulation pipe having a solution circulation pump 7 to a regenerator. 2 is connected to the regenerator 2, and the pump 7 supplies the regenerator 2 under pressure, and the concentrated solution separated in the regenerator 2 is introduced through the pressure reducing valve 4B. I try to absorb it with high ability. Between the absorber 6 and the regenerator 2, there is heat exchange between the high temperature concentrated solution separated by the regenerator 2 and the low temperature dilute solution fed by the absorber 6 to achieve thermal economy. A solution heat exchanger 8 is provided. Here, a cooling water circuit 9 is connected to each of the condenser 3 and absorber 6 in order to condense the refrigerant vapor, and as shown in the figure, the cooling water is passed through the absorber 6 to the regenerator 2. Heat is removed from the concentrated solution which is separated by the solution heat exchanger 8 and the pressure reducing valve 4B, and then heat is removed from the high temperature separated refrigerant vapor which is passed through the condenser 3. and,
In the case of air conditioning, the hot water obtained by absorbing heat is led to a cooling tower or the like. In this way, thermal efficiency can be improved.

従来技術は次のような欠点や問題点があつた。 The evaporator 5 used in the above-mentioned absorption air conditioner has a structure as shown in FIG. That is, the evaporator 5 includes an evaporation tube 51 made of a copper tube and a tube plate 52 made of a stainless steel or mild steel plate.
The fins 53 made of aluminum or steel are fitted into the through holes drilled in the fins 53 and the fins 53 made of aluminum or steel are fitted, and the joint between the evaporation tube 51 and the tube plate 52 is connected by silver brazing 5.
4. However, in the case of such conventional technology, since the inside of the main body of the water-lithium chlorine absorption type air-conditioner is maintained at a high vacuum, it is necessary to prevent leakage from the outside. Therefore, it is necessary to apply silver brazing 54 to the joint between the evaporation tube 51 made of a steel pipe and the tube sheet 52 made of a stainless steel plate. Leak inspection and silver brazing modifications were required. In addition, if the tube sheet 52 is made of a mild steel plate that is somewhat easy to silver-braze to a stainless steel plate, the part where the tube sheet 52 is used is the evaporator 5, which prevents rusting and leaks due to condensation. Painting is required to avoid this risk. Therefore, the above prior art has the following drawbacks and problems.
(1) 銀ろう付のため、材料費が高くなる。(1) Material costs are high due to silver brazing.
(2) 銀ろう付は、これを施工する上で技術的に高
度であるため、不良率が高くなる。(2) Since silver brazing is technically sophisticated, the defect rate is high.
(3) 管板５２の材料が軟鋼板のものにあつては組
