Based upon the idea of a new hybrid system with combined cycle of solar heating and refrigeration and simulation calculations of the hybrid system, a device for experiment is constructed, and some experimental works of simulating solar radiation are carried out. The results of these experiments show that this hybrid system is very efficient. On the condition of accepting 49MJ heating energy from outer circumstances, the hybrid system can provide 10.5 kg -2℃ ice and 150kg\ 98℃ hot water, the coefficient of performance of refrigeration cycles is COP\-\{cycle\}=0.386, the coefficient of performance of the system is COP\-\{system\}=0.067, the heating efficiency to the water in the tank is η=0.758. The successful experimental works show that solar energy can be utilized quite efficiently.
