Experimental investigation of a new resorption cycle using ammonia as refrigerant.

Author(s) : HELLE K., MORSCHEL M., PEIL S., et al.

Summary

Using the resorption principle and two solvent loops a new advanced absorption chiller with 1-2 kW cooling power has been developed. In contrast to classical absorption design strategies the hot ammonia gas is not condensed but absorbed in a second solvent loop. Instead of evaporation the absorbed ammonia is desorbed to produce cooling energy. Using two solvent loops a rectification is avoided. The reduced pressure compared with pure ammonia evaporation allows for the application of commercially available and inexpensive plastic raw materials. The construction method makes compact plants possible, thus enabling mobile applications in near future. Design and experimental results of a prototype with 1-2 kW cooling power are presented along with the start-up strategy and process stability. Its advantages over existing technology will be discussed.
