An absorption chiller makes it possible to generate cold using thermal energy. In contrast to a compression chiller, a two-substance system is used in which a solvent circuit serves as a thermal compressor. First, the refrigerant is vaporized in an expander using thermal energy. The refrigerant is then cooled using a condenser and fed into a virtually evacuated evaporator. There, the refrigerant evaporates while absorbing the ambient heat and the actual efficiency is created. The refrigerant is then fed into the absorber, where it is absorbed by the solvent. A solvent pump now feeds the enriched solution back to the ejector. From there, the process begins again.
