Absorption cooling device

Absorption cooling device including

• an expeller (7) for expelling a working agent in gaseous form from enriched solvent for depleting said working agent in a solvent circuit (5),
• a first connecting line (11) for transferring said expelled working agent from said expeller (7) to a condenser (9) for condensation of said expelled working agent,
• a second connecting line (15) for transferring said condensated working agent from said condenser (9) to an evaporator (13) for evaporating said condensated working agent with absorption of heat from a space to be cooled,
• a third connecting line (16) for transferring said evaporated working agent from said evaporator (13) to an absorber unit (17),
• fourth connecting line (21, 35) for transferring said solvent depleted with working medium from said expeller (7) to said absorber unit (17), said absorber unit (17) comprising a counterflow exchange path (47) extending over a given high difference (51, 53), into which said third connecting line (16) ends on a low level (53) and into which said fourth connecting line (21, 35) ends on a higher level (51) so that in said absorber unit (17) said working agent in said solvent enriches;
• a fifth connecting line (19) for transferring said solvent enriched with working agent from said absorber (17) to said expeller (7),
• wherein at least a part of said fifth connecting line (19) is filled with a liquid portion of said solvent and a first liquid level (25) of said solvent is formed in an area (23) of an end facing said expeller (7), of said fifth connecting line (19) or in said expeller (7) and a second liquid level (29) corresponding with said first liquid level (25) through said fifth connecting line (19) is formed,
• characterized in that
• the total surface of said second liquid level (29) is smaller than ten times, in particular smaller than eight times, in particular smaller than five times, in particular smaller than three times and in particular smaller than twice a medium cross-section of said fifth connecting line (19) or said fourth connecting line (21, 35).
