    • A method for preparing a ternary or higher zeotropic refrigerant mixture comprising components of different volatilities is described. The method comprises: mixing together the less volatile components of the mixture in a pre-blending process; and separately adding the most volatile component to the pre-blended mixture by pressure or mass flow control so that the desired initial liquid composition is attained. The liquid zeotropic refrigerant mixture that is prepared may be transferred from a container in which it is held to another container or to a piece of equipment that is to use the refrigerant mixture. This method comprises the steps of: removing at least a portion of the prepared liquid zeotropic refrigerant mixture from a container in which it is held; charging the liquid zeotropic refrigerant mixture that is removed to another container or to a piece of equipment in which it is to be used; and adding at least the most volatile component of the refrigerant mixture to the holding container to compensate for the removal of liquid refrigerant mixture therefrom.
    • 描述了一种制备包含不同挥发性组分的三元或更高级非共沸混合制冷剂混合物的方法。 该方法包括:在预混合过程中将混合物中较不易挥发的组分混合在一起; 并通过压力或质量流量控制分别将最易挥发的组分加入到预混合混合物中,使得获得所需的初始液体组合物。 制备的液体非共沸混合制冷剂可以从其被容纳的容器中转移到另一个容器中,或者转移到使用制冷剂混合物的一件设备上。 该方法包括以下步骤:将至少一部分制备的液体非共沸混合制冷剂混合物从其保持的容器中除去; 将除去的液体非共沸混合物装入另一个容器或使用其中的一件设备; 并且至少将所述制冷剂混合物中最易挥发的组分添加到所述保持容器以补偿从其中除去液体制冷剂混合物。
