Abstract

This paper experimentally investigates the chemisorption refrigeration technology, mixing carboncoated Nickel and Iron (Ni@C and Fe@C) with the conventional composite of MnCl2-EG as the sorbents. A modified manufacture methodology is developed and reported. The thermal conductivity is improved by the nanomaterials with a maximum increase of 3.0 %, and adsorption and desorption are accelerated as well. SCP of the sorbents is enhanced up to 11.02 %, indicating the enhancement of the low-grade heat conversing into the cooling power, by the application of MnCl2-EGNi/Al@C chemisorption.
