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
【課題】良好なエネルギ効率を有する冷凍サイクルシステムを提供する。【解決手段】冷凍サイクルシステムは、圧縮機、凝縮器、膨張弁及び熱交換器を備える。熱交換器は、空気通路を通過する空気、冷媒通路を通過する前記冷媒、及び蓄冷材間で熱交換を行い、蓄冷熱伝導率と放冷熱伝導率とが異なるように構成されている。圧縮機への駆動力は、空気流路を通過する空気の温度変化に含まれる最高温度が蓄冷材の潜熱温度領域の下限温度より高く、かつ、潜熱温度領域の上限温度以下となるように、又は、温度変化に含まれる最低温度が潜熱温度領域の上限温度より低く、かつ、前記潜熱温度領域の下限温度以上となるように制御される。【選択図】図5
