Abstract
Disclosed is a method and apparatus for refrigeration utilizing a combined mechanical and absorption cycle. Two immiscible or only partly miscible refrigerants are mixed and evaporated in an evaporator to cool a process stream. The refrigerants are separated in an absorber which absorbs one of the refrigerants from the vapor mixture. The non-absorbed refrigerant vapor is compressed and condensed, while the absorbed refrigerant is desorbed and condensed to produce respective liquid refrigerant streams to the evaporator. Optionally the vapor mixture from the evaporator is compressed in a first stage of compression prior to passing to the absorber.
