PROBLEM TO BE SOLVED: To provide a refrigeration cycle system exhibiting sufficient energy efficiency.SOLUTION: A refrigeration cycle system includes a compressor, a condenser, an expansion valve, and a heat exchanger. The heat exchanger exchanges heat among air passing through an air passage, a refrigerant passing through a refrigerant passage, and a cold storage material, and cold storage heat conductivity and cold radiation heat conductivity are different from each other. Driving force to the compressor is controlled so that the highest temperature contained in temperature variation of the air passing through the air flow passage is higher than a lower limit temperature in a latent heat temperature region of the cold storage material and is equal to or lower than an upper limit temperature in the latent heat temperature region, or the lowest temperature contained in the temperature variation is lower than the upper limit temperature in the latent heat temperature region and is equal to or higher than the lower limit temperature in the latent heat temperature region.SELECTED DRAWING: Figure 5
