摘要：

This paper presents a mathematical model that has been developed to study the effect of the water storage tank volume and working fluids mass flow rate on the efficiency of a Hybrid Solar Collector (HSC) system for different Romania climates. The thermal storage system consists of three separate fully mixed tanks. It means that the temperature in the tank is uniform. The simulation results show that the system performance increases about 2.1% for a 500L volume of the storage tank with constant air flow rate 0.06 kg/s compared to the system with 300L volume of storage tank. Moreover, the HSC system performance is significantly affected by the air channel shape. The efficiency of the HSC system can be improved through the use a large thermal storage system.
