A new waste heat district heating system with CHP based on ejector heat exchangers and absorption heat pumps (DH-EHE) is presented to decrease heating energy consumption of existing CHP systems by recovering waste heat of exhausted steam from a steam turbine, which could also increase heat...

A complete review of working fluids of absorption cycles is presented. Absorption cycles contain absorption heat pumps, absorption chillers and absorption transformers. Working fluids are divided into five series according to different absorbents.
