AIR-COOLING ABSORPTION TYPE REFRIGERATOR

PROBLEM TO BE SOLVED: To make an air-cooling absorption type refrigerator compact by reducing a pressure drop in a heat transfer pipe of an air-cooling absorber.SOLUTION: An air-cooling absorption type refrigerator includes a regenerator 1, air-cooled condensers 4, 8, evaporators 26, 29, air-cooled absorbers 12, 19, a solution heat exchanger 45, a refrigerant pump 43, a concentrated solution pump 44, and a diluted solution pump 49. The air-cooled absorber 12 has an upper header 14, an upper-stage air-cooled heat exchanger 15, an intermediate header 16, a lower-stage air-cooled heat exchanger 17, and a lower header 18 arranged in order from above, and includes a refrigerant steam pipe 37 for guiding refrigerant steam from the evaporators to the upper header, and a branch refrigerant vapor pipe 37' branching off halfway from the refrigerant vapor pipe and connected to the intermediate header. A partition plate is provided in the intermediate header, and includes an upper space as an intermediate tank part where a solution from the upper-stage air-cooled exchanger gathers and also have a scatter hole formed to scatter the solution of the intermediate tank over the lower-stage air-cooled heat exchanger, and the branch refrigerant vapor pipe is connected to a lower space of the partition plate in the intermediate header.
