A1 Wang, Liwei T1 EXPERIMENTAL STUDY OF A THERMALLY DRIVEN COMPOSITE ADSORPTION REFRIGERATOR JF Heat Transfer Research JO HTR YR 2015 FD 2014-12-17 VO 46 IS 4 SP 333 OP 345 K1 thermal energy K1 composite adsorbent K1 adsorption refrigerator K1 mass recovery AB A thermally driven adsorption refrigerator using CaCl2 (calcium chloride)/AC (activated carbon) composite adsorbent has been developed. Through the optimal design, fewer valves are used, the vibration and noise are lowered, and the size of the adsorption bed is decreased, i.e., the adsorption refrigerator is more compact. The performance of the refrigerator is tested, and the experimental results showed that the cooling capacity, COP (coefficient of performance), SCP (specific cooling power per kilogram of adsorbent), and VCD (volume cooling density) are equal respectively to 3.74 kW, 0.26, 440.0 W kg−1 and 69.73 kW·m−3 under the conditions of 140°C heating temperature, 28°C cooling water temperature, and −12.5°C evaporation temperature. The system's dynamic characteristics indicated the cyclical variations in temperature and pressure as well as the obvious eff ects of desorption action and mass recovery process on the system performance. Meanwhile, experimental results showed that the performance of the system can be improved significantly by the higher heating temperature, mass recovery process, and the reasonable ratio of the adsorption/desorption time to the mass recovery time.
