Résumé

A novel CaCl2/expanded graphite-NH3 adsorption refrigerator is developed and tested. Only three valves are installed in this refrigerator and they all work at the same positive pressure condition, so the operating reliability of the refrigerator is greatly improved. The experimental results show that the refrigerating power Q(CP), COP, SCP, electricity COP(El), and volume refrigerating density Q(CP-V) of the refrigerator are 11.4 kW, 0.27, 422.2 W/kg, 32.6 and 57 kW/m3, respectively, under the following conditions: the temperature of heating vapour is from 120 to 140.3°C, the cooling water temperature is 25°C, the evaporation temperature is -15°C, the heating/cooling time is 25 min including 45 s mass recovery time. The SCP and volume refrigerating density of this refrigerator are about 1.8 times and 1.5 times that of the maximum of the former test results by other researchers.
