Method for operating an absorption refrigeration unit as well as an absorption refrigeration unit

Absorption refrigerating unit comprising

• a pump pipe (3) vertically arranged in the heatable expeller (1),
• a solvent separator (8) subsequent to said expeller (1),
• a condenser (10) subsequent to said solvent separator (8) and slightly inclined downwardly in direction of flow,
• an evaporator (12) subsequent to said condenser (10) and arranged in the chamber to be cooled,
• an absorber (14) subsequent to said evaporator (12) and
• an inlet pipe (17) for introducing a solution poor in working agent into said absorber (14), wherein the individual components of the unit are designed for generally continuous supply of thermal energy and are optimized for power increase such that
• said solvent separator (8) is formed as straight pipe extending vertically and directly following said pump pipe (3) of said expeller 81) and merging into said condenser (10) with a knee (9) and
• the length of the pipe forming said solvent separator (8) amounts to 35 to 55 percent of said pump pipe (3) and
• said pump pipe (3) of said expeller (1) is shortened to an admissible minimum and
• said inlet pipe (17) for the poor solution has a cross-section corresponding to 0.35 to 0.55 times the flow cross-section for the poor solution in said expeller (1).
