Abstract
In this paper the design scheme of a new continuous combined solid adsorption–ejector refrigeration and heating hybrid system driven by solar energy was proposed, the thermodynamic theory of this system was constructed, and the performance simulation and analysis were made under normal working conditions. In the combined hybrid system, zeolite–water working pair was chosen in view of environment protection and solar energy utilization. From simulation the combined hybrid system had a cooling capacity of 0.15 MJ per kg zeolite in the day-time and a cooling capacity of 0.34 MJ per kg zeolite in the evening, and could furnish 290 kg hot water at 45 °C for family use. Furthermore, under the same working conditions, compared with an adsorption system without an ejector with a COP of 0.3, the combined system's COP was improved by 10% totally and reached 0.33.
