Title:
吸収式冷凍機
Document Type and Number:
Japanese Patent JP7080001
Kind Code:
B2
Abstract:
To provide an absorption-type refrigerator which can increase a solution spray amount by a low-pressure absorber more than a high-pressure absorber, increases a wet heat transmission face of a vertical pipe in which a solution flows down, and can maximize an effective heat transmission area which can contribute to heat exchange.SOLUTION: A low-pressure absorber 15 and a high-pressure evaporator 16 have a plurality of pieces of vertically-extending vertical pipes (heat transmission pipes) 14, respectively, the inside of each vertical pipe 14 constitutes the high-pressure evaporator 16, and the outside of the vertical pipe 14 constitutes the low-pressure absorber 15. Then, solution piping 29 connected to a regenerator 1, and sending a solution which is condensed by the regenerator 1 to a high-pressure absorber 6 and the low-pressure absorber 15 has a branch part A, and is branched to solution piping 30 for sending the solution to the high-pressure absorber 6, and solution piping 31 for sending the solution to the low-pressure absorber 15.SELECTED DRAWING: Figure 1
