In this paper, one novel heat pipe solar adsorption chiller with mass-heat recovery was designed. 65 kg of micro-porous silica gel was used as adsorbent in each adsorbent bed. The influence of operating conditions on the chiller was investigated. The chiller was applied in Green Building in Dezhou city (north latitude of 36°41′) in China. Under the typical summer weather conditions, the average thermal efficiency of solar collector, the average COP (coefficient of performance) of the adsorption refrigerator and the average solar COP of the system are 0.36, 0.44 and 0.16, respectively. The results show that the adsorption cooling performance rises as the hot water inlet temperature, chilled water outlet temperature rise, and it declines as the cooling water inlet temperature rises. The performance can be improved by mass-heat recovery significantly. When the hot water inlet temperature, cooling water inlet temperature, chilled water outlet temperature are 79.0 °C, 25.4 °C, 13.7 °C, respectively, the cooling capacity and COP are 17.9 kW and 0.63, respectively.
