    • Disclosed is a refrigeration or air conditioning system comprising a refrigeration cycle that uses a refrigerant mixture of at least two kinds of refrigerants consisting of 45 to 55 weight percent of R32 and 55 to 45 weight percent of R125, and that includes at least a compressor, a condenser, a throttling device, and an evaporator. In some cases the temperature and pressure in a line leading from the inlet of the evaporator to the suction port of the compressor is controlled below a specific temperature and pressure point corresponding to the critical decomposition point of a clathrate that contains water as a host solution and the refrigerant mixture as guest molecules, and within a prescribed control range bounded by a formation limit line of the clathrate and a saturated liquid pressure line representing the pressure versus temperature relationship of saturated liquid of the refrigerant mixture (a first control mode), and a dryer for moisture removal is provided in the refrigeration cycle.
    • 公开了一种制冷或空调系统,其包括制冷循环,其使用由45至55重量%的R32和55至45重量%的R125组成的至少两种制冷剂的制冷剂混合物,并且至少包括压缩机, 冷凝器,节流装置和蒸发器。 在一些情况下,从蒸发器入口到压缩机吸入口的管线中的温度和压力被控制在对应于包含水作为主体溶液的包合物的临界分解点的特定温度和压力点, 作为客体分子的制冷剂混合物,并且在由包合物的形成界限线限定的规定的控制范围内,表示制冷剂混合物的饱和液体(第一控制模式)的压力 - 温度关系的饱和液体压力线,以及 在制冷循环中提供用于除湿的干燥器。
