The present invention relates to an absorber of an absorption type air conditioner that generates a rare solution by allowing a refrigerant vapor to be absorbed in a concentrated solution in an absorption type air conditioner that outputs cooling and heating using a lithium bromide solution. By dispersing the agricultural liquid into a large number of solution distributors by the distribution means, the agricultural liquid flows thinly to the surface of the cooling pipe to improve the absorption efficiency of the absorber and at the same time improve the cooling and heating efficiency of the absorption air conditioner. Relates to an absorber.

In general, various types of absorption air conditioners for outputting heating and cooling using lithium bromide solution have been proposed in various forms.

An example is Patent Application No. 94-10823 filed on May 16, 1994 in the Republic of Korea by the present applicant.

As shown in FIGS. 1 and 2, the absorption type air conditioner according to the prior patent application 94-10823 includes a generator 10 for separating a rare solution into a concentrated solution and a refrigerant vapor, and in the generator 10. In an absorption type air conditioner including condenser 20 for condensing the separated refrigerant steam to generate an output of cooling and heating, the refrigerant liquid condensed in the condenser 20 is evaporated and the refrigerant vapor passes through one surface of the refrigerant liquid. The evaporator 30 in which the refrigerant separating member 301 is disposed to pass through, and the refrigerant vapor passing through the refrigerant separating member 301 of the evaporator 30 are absorbed by the agricultural solution generated from the generator 10 and are a rare solution. Refrigerant vapor passing through the refrigerant separation member 301 to be converted to the same and at the same time the solution separation member 401 that blocks the concentrated solution supplied from the generator 10 to the evaporator 30 is one side Excreted in It is characterized by consisting of an absorber (40).

In addition, the absorber 40 is provided with a cooling pipe 43 for guiding the flow of cooling water, and the concentrated liquid separated from the generator 10 is disposed on the surface of the cooling pipe 43 at the upper part of the absorber 40. The solution distributor 42 which inject | pours a concentrated solution so that it may flow to the inside may be arrange | positioned.

The present invention has been made in view of the above-described problems, and an object of the present invention is to supply the agricultural liquid to the absorber so that the liquid film thickness of the agricultural liquid flowing to the surface of the cold and bad pipe is thinner, and the agricultural liquid evenly cools the cold pipe. By absorbing the refrigerant vapor to be more smoothly absorbed in the agricultural solution and at the same time the absorber of the absorption air-conditioner that can improve the heating and cooling efficiency by easily dissipating the heat of absorption generated when the refrigerant vapor is absorbed in the agricultural solution To provide.

In order to achieve the above object, the absorber of the absorption type air conditioner according to the present invention includes a plurality of cooling pipes disposed through the inside of the absorber so as to lower the temperature inside the absorber, and the cooling liquid generated from the generator passes through the absorber. In the absorber of the absorption air conditioner having a guide pipe connected to the absorber so as to flow to the surface of the pipe, the guide pipe is made of a plurality so that the agricultural liquid is ejected toward the cooling pipe in a plurality of places inside the absorber, The absorber side end of the guide pipe is characterized in that the solution dispersing member for dispersing the concentrated solution so that the liquid film thickness of the concentrated solution flows to the surface of the cooling pipe is coupled.

According to the absorber of the absorption type air conditioner according to the present invention, since the liquid film thickness of the concentrated liquid flowing through the surface of the cooling pipe is reduced, the refrigerant vapor is more smoothly absorbed into the agricultural liquid, and the cold rice vapor is absorbed into the agricultural liquid. The heat of absorption can be more easily released to the outside of the absorber.
