ABSORPTION REFRIGERATOR OF TWO-STEP ABSORPTION METHOD

摘要

PROBLEM TO BE SOLVED: To prevent cavitation of a solution pump and perform energy-saving operation in a two-step absorption type absorption refrigerator. SOLUTION: A low temperature absorption liquid pipe 30 between a low temperature absorption liquid pump 22 and a solution heat exchanger 2 and an absorption liquid pipe 31 for sprinkling between the solution heat exchanger 2 and a first absorber 1A are connected via an absorption liquid branch pipe 32 and an absorption liquid pool part 33A at a lower part of the first absorber and an absorption liquid pool part 33B at a lower part of the second absorber are connected via a liquid pool communication pipe 34. At the time of starting and controlling heating heat volume by load change, to avoid liquid quantity shortage of the absorption liquid pool parts of the lower part of the first absorber and the lower part of the second absorber and unbalanced state of right and left absorption liquid pool parts, an automatic first bypass valve 41 is provided at the absorption liquid branch pipe 32 and an automatic second bypass valve 42 is provided at the liquid pool communication pipe 34.
