Résumé

The objective of this study is to estimate cooling and heating energy from adsorption refrigeration and heat pump system driven by solar thermal energy. The system composed of a CPC type collector and zeolite (FAM-Z02)/water adsorption system. We evaluated numerically the supplied cooling and heating energy at 20°C from the system every hour for a year with an assumption of the adsorption equilibrium theory using solar irradiation, dry air and wet-bulb temperatures at Fukuoka of Japan in 2004. The cooling and heating energies decreased 10 % and 4 % by counting heat capacity of the adsorbent heat exchanger. The ratio of supplying energy to the collected solar was also 1.16 which was 0.08 smaller than the ratio without a counting the heat capacity. Additionally, this influence was significant at low heat source temperature condition. Consequently, a development of an adsorbent heat exchanger with low heat capacity will be urgent issue.
