A new type of consolidated composite sorbent for NH4Cl/CaCl2/MnCl2 is developed by the mixture of ENG-TSA (expanded natural graphite treated by the sulfuric acid)

and its sorption/desorption process is tested under non-equilibrium conditions.Compared with the theoretical Clapeyron curves under equilibrium conditions of three kinds of salt

the consolidated composite sorbent shows combining properties of three salts but there are also some differences.The consolidated composite sorbent shows some properties of the three metal chlorides respectively during the sorption/desorption experiments under non-equilibrium conditions.However

there is almost no sorption hysteresis which is prevalent in single salt-ammonia complexing process.On this basis

the COP and SCP of a single-stage sorption refrigeration cycle using the composite sorbent is calculated.The experiments prove that the performance of the consolidated composite multi-salt sorbent is better than single salt sorbents.
