Operation analysis of the zeolite-NH3-H2O sorption chiller.

Summary

This paper presents a novel type of zeolite-NH3-H2O sorption chiller. The use of zeolite-NH3-H2O makes it possible to improve the running pressures. A zeolite-NH3-H2O sorption chiller was tested to obtain the running pressure at near ambient pressure. The large differential pressure between NH3 and H2O at the evaporating temperature ensured that most of the vapour was NH3 (adsorbed by zeolite), so that the ammonia distiller in absorption refrigeration is no longer needed. The NH3 vapour is absorbed by H2O in the condenser during the desorption process and the pressure of the system is much lower than that encountered in pure NH3 condensation. Results are promising.
