- Abstract:
- A closed-cycle solar-powered adsorption cooling system is designed. The system is mainly composed of the evacuated tubular solar collectors with an area of 150 m2, two adsorption chillers with a rated cooling capacity of 15 kW, a cooling tower, fan coils and circulating pumps.The experiments were carried out to study the operating characteristics and the performance of the system.It is found that the operation of the system presents wave characteristics because of low water capacity.The water temperatures of the inlet and the outlet of the solar collector array cyclically swing since the water entering the solar collector array comes directly from the adsorption chillers.Besides, the inlet water temperature of the adsorption chillers varies distinctly.However, the cooling effect of the system is satisfactory.Compared with an open-cycle system, the closed-cycle system has the advantage of a high electric COP(coefficient of performance)because of the reduced use of circulating pumps.
