COLD GENERATION METHOD IN ABSORPTION-DIFFUSION REFRIGERATING AGGREGATE Russian patent published in 2007 - IPC F25B15/10 

FIELD: domestic refrigerating equipment.

SUBSTANCE: method is realized due to supplying liquid cooling agent to separator and further to additional evaporator. Cooling agent is supplied from lower part of evaporator by means of vapor-lifting pump. The last works with use of vapor of liquid cooling agent generated during heat exchange process between thermally loaded portions of refrigerating aggregate and liquid cooling agent from cavity of lower part of additional evaporator. Liquid cooling agent from cavity in lower part of additional evaporator by means of additional vapor-lifting pump operating with use of vapor of cooling agent from separator and mounted in communication line by liquid cooling agent vapor between separator and condenser is fed to additional separator. Liquid cooling agent is fed to additional separator and then through hydraulic seal it is directed to next additional evaporator. Liquid cooling agent is fed to additional separator till level no less than that of adding liquid cooling agent to next additional evaporator. Evaporator, additional evaporator and next additional evaporator are mutually coupled by vapor. Evaporator and additional evaporator are mounted in liquid cooling agent communication line between condenser and next additional evaporator.

EFFECT: lowered size of evaporator of absorption-diffusion refrigerating aggregate.
