开发了一种新型零能耗冷室（ZECC），由两个冷却系统、一个太阳能驱动的吸附式制冷机和一个蒸发冷却系统组成，并被评估为低成本、环保的冷藏库，用于储存中等呼吸率的水果。太阳能驱动的吸附式制冷机由含有活性炭作为吸附剂的太阳能集热器、冷凝器和蒸发器组成，通过蒸发甲醇并将其吸附在活性炭上来冷却水，然后制冰。吸附在活性炭上的甲醇通过施加太阳热而解吸。然后用冰来冷却存储空间，这可以在不需要电力的情况下长时间完成。蒸发冷却系统还通过从含有湿填料的湿墙壁蒸发水来冷却存储空间。两个冷却系统的结合使用将新 ZECC 的平均内部温度降低至 12.07 °C，而外部平均温度为 31.5 °C，并将西红柿的保质期从 7 天延长至 23 天。这些结果表明，这里提出的新 ZECC 成本低且节能，可用于在没有电力的地区储存水果和蔬菜。
A new zero energy cool chamber (ZECC) consisting of two cooling systems, a solar-driven adsorption refrigerator and an evaporative cooling system, was developed and then evaluated as low-cost and eco-friendly cooling storage for storing fruit with moderate respiration rates. The solar-driven adsorption refrigerator, consisting of a solar collector containing activated carbon as an adsorbent, a condenser and an evaporator, cools water based by evaporating methanol and adsorbing it on activated carbon, and then makes ice. The methanol adsorbed on the activated carbon is desorbed by applying solar heat. The ice is then used to cool the storage space, which can be done for a long time without the need for electricity. The evaporative cooling system also cools the storage space by evaporating water from the wet walls containing wet filler. The combined use of two cooling systems reduced the average inside temperature of the new ZECC to 12.07 °C compared with an average outside temperature of 31.5 °C and extended the shelf life of tomatoes from 7 to 23 days. These results suggest that the new ZECC proposed here is low-cost and energy-saving and is useful for storing fruit and vegetables in areas where electricity is unavailable.
