Abstract

A small refrigerator based on resorption technique, employed MnCl ₂ and NH₄Cl as sorbent salts and ammonia as refrigerant, was presented for simultaneously cooling at 0-6 °C and freezing at -16 to -14.5 °C in this work. The cooling capacity of this device was investigated by measuring the mass amount of the ice generated during a certain period of 3 h operation, and the experiments were conducted at different ambient temperature ranging from 20 °C to 35 °C. The total cooling capacity was calculated 475 kJ per kg of NH₄Cl salt, and the mean specific cooling power (SCP) was 43 W per kg of NH₄Cl salt, the effective cooling production responsible for making ice accounted for 25-42% of the total cooling capacity depending on the different operating conditions studied in this work.
