PROBLEM TO BE SOLVED: To improve cooling effects in a cooler and securely dry and store a stored object by improving dehumidifying effects by sending a gas refrigerant at as low temperature as possible to the cooler even when reheating is performed.SOLUTION: This drying storage system includes: a compressor 1 discharging a gas refrigerant an exterior condenser 2 for cooling and condensing the gas refrigerant discharged from the compressor 1 a liquid receiver 3 for receiving the gas refrigerant from the exterior condenser 2 an expansion valve 4 for injecting the gas refrigerant from the liquid receiver 3 the cooler 5 for cooling internal air within a warehouse W by heat exchange with the gas refrigerant, blowing out the internal air to inside of the warehouse W and sending the gas refrigerant of which temperature is raised through the heat exchange to the compressor 1 an interior first condenser 6 for warming the blown out air from the cooler 5 by heat exchange with the gas refrigerant and blowing out the air to inside of the warehouse W and an interior second condenser 7 for further warming the blown out air from the interior first condenser 6 by heat exchange with the gas refrigerant and blowing out the air to inside of the warehouse W. The gas refrigerants made to flow out from the interior first condenser 6 and interior second condenser 7 are cooled and condensed by the exterior condenser 2.COPYRIGHT: (C)2010,JPO&INPIT【課題】 再加熱をしても冷却器にできるだけ低温のガス冷媒を送ることができるようにし、冷却器での冷却効果を向上させ、除湿効果を向上させて収容物の乾燥及び貯蔵をより確実に行なう。【解決手段】 ガス冷媒を吐出する圧縮機1と、圧縮機1から吐出されたガス冷媒を冷却凝縮する庫外凝縮器2と、庫外凝縮器2からのガス冷媒を受ける受液器3と、受液器3からのガス冷媒を噴射する膨張弁4と、倉庫W内の内気をガス冷媒との熱交換により冷却して倉庫W内に吹き出すとともに熱交換により温度上昇したガス冷媒を圧縮機1に送る冷却器5と、冷却器5からの吹出空気をガス冷媒との熱交換により加温して倉庫W内に吹き出す庫内第一凝縮器6と、庫内第一凝縮器6からの吹出空気をガス冷媒との熱交換により更に加温して倉庫W内に吹き出す庫内第二凝縮器7とを備え、庫内第一凝縮器6及び庫内第二凝縮器7から流出するガス冷媒を庫外凝縮器2で冷却凝縮させる。【選択図】図1
