Multi-effect absorption refrigerating machine

摘要

The present invention is provided with an evaporator, a primary absorber, a plurality of generators, a condenser and a direct contact type heat exchanger which is provided with auxiliary evaporator-absorber stages in a plural set. These evaporator-absorber stages in a plural set are divided into a plurality of groups and connected so that a solution is sent from the final absorber stage of each group into each generator. By this construction, the solution in a first generator of a plurality of generators can be made to work at a lower level of temperature than usual.
