Solution pump 1
1. Consists of a refrigerant pump 12. The aqueous lithium bromide solution in the high-temperature regenerator 2 is heated by the burner 9 to generate refrigerant vapor and concentrate the solution. The generated refrigerant vapor passes through the refrigerant line 13 to the heating pipe 14 in the low temperature regenerator 3.
flows into. The lithium bromide aqueous solution in the low-temperature regenerator 3 is
It is heated by the refrigerant vapor in the heating tube 14, and refrigerant vapor is also generated here. Here, the refrigerant vapor in the heating tube 14 is liquefied, and the lithium bromide aqueous solution is concentrated.

冷媒ライン２１から蒸発器５に流入する。The refrigerant vapor generated in the low temperature regenerator 3 enters the condenser 4 through the refrigerant line 15, while the liquefied refrigerant passes through the refrigerant line 16 and joins the refrigerant in the refrigerant line 17. The condenser 4 has fins 18 on the outside of the tube, and since outdoor air flows through the fins 18 by a fan 19, the refrigerant vapor in the condenser 4 is cooled and liquefied. The liquid refrigerant flows from the refrigerant line 17, merges with the liquid refrigerant from the refrigerant line 16, and further merges with the liquid refrigerant discharged from the refrigerant pump 12.
The refrigerant flows into the evaporator 5 from the refrigerant line 21 .

イン２５、冷媒ポンプ１２、冷媒ライン２６を通って、
再び冷媒ライン２１に戻る。ここで蒸発した冷媒蒸気は
、冷媒流路４８を上昇して吸収器６に流入する。Since the inside of the evaporator 5 is maintained under reduced pressure, the liquid refrigerant evaporates and its latent heat is taken away from the cold water in the cold water pipe. The liquid refrigerant that has not completely evaporated accumulates in the refrigerant reservoir 24 and passes through the refrigerant line 25, the refrigerant pump 12, and the refrigerant line 26.
It returns to the refrigerant line 21 again. The refrigerant vapor evaporated here ascends the refrigerant flow path 48 and flows into the absorber 6.
吸収器６は垂直管２８及び管外にあるフィン２９で構成

The concentrated solution that has passed through the concentrated solution line from the A solution pump 11 is sprayed from the sprayer 30. The sprayed concentrated solution is cooled by the outdoor air flowing outside the vertical pipe 28 while flowing down along the wall of the vertical pipe 28, and its water vapor pressure is lowered. There, it absorbs the refrigerant vapor from the evaporator 5 and becomes a dilute solution.
吸収器６のまわりにはダクト３２があり、そのダク１−
は、吸収器６を包み、ファン２ｏの吸込ダクトになる。There is a duct 32 around the absorber 6, and the duct 1-
wraps around the absorber 6 and becomes the suction duct for the fan 2o.

風が生じ、この風によって吸収器フィン２９及び垂直管
２８が冷却される。An air passage 34 is formed between the absorber vertical pipe 28 and the duct 32, and an upward wind is generated in the air passage 34 by the rotation of the fan 2o, and the absorber fins 29 and the vertical pipe 28 are cooled by this wind. .
また、風路３４を流れる空気は、吸気口３３を通して室
外空気が吸引される。Furthermore, outdoor air is sucked into the air flowing through the air passage 34 through the intake port 33 .

An air-cooled absorber is thus realized. Also, fin 28
A slit 35 is provided in order to improve heat transfer. Furthermore, within the vertical tube 28 there is a spiral plate or padding (
(not shown) to improve contact between the concentrated solution and the pipe wall and between the concentrated solution and the refrigerant. Additionally, the inner surface of the vertical tube 28 may be provided with fins or grooves (not shown) to improve intra-tube heat transfer.

2, the dilute solution in the heat transfer tube 63 or the dilute solution partially flowing together with the refrigerant vapor and the refrigerant vapor rising in the refrigerant flow path 48 exchange heat, and the dilute solution is further cooled to reduce the lithium bromide concentration. This creates a solution with even lower levels of water and at the same time promotes the wicking action. The concentration of lithium bromide in the dilute solution made here is
Because it is sufficiently thin, water chillers with air-cooled absorbers can be realized. The dilute solution sucked into the solution pump 10 is preheated by the solution heat exchanger 7 from the dilute solution line 36, and is divided into streams and enters the low temperature regenerator 3 from the dilute solution line 38. Further, the remaining dilute solution is preheated by the solution heat exchanger 7 and flows into the high temperature regenerator 2 through the dilute solution line 39.

It merges with the concentrated solution that has flowed into the middle part of the heat exchanger 7, further heats the dilute solution, and then flows into the absorber 6 from the concentrated solution line 31.

ポンプ１０に吸引される。The second absorber 62 includes the evaporator shell 27 and the refrigerant flow path 48
It consists of a jacket 65 provided on the outside. In the second absorber 62, heat is exchanged between the dilute solution flowing in the jacket 65 or partly with the refrigerant vapor and the refrigerant vapor in the evaporator 6 and the refrigerant flow path 48, and the dilute solution is further cooled. As a result, the lithium bromide concentration is further reduced to a solution, which is sucked into the solution pump 10.
