    摘要: A casting mold member is produced from a master which has a section with a spirally symmetrical outer contour such that the casting mold member surrounds the section in an azimuthally closed manner with respect to the axis of symmetry. The casting mold member is used to provide a casting mold. The casting mold member is filled by feeding a cast iron melt, and solidifying the melt by using a graphitization pressure to prevent cavities and pores in the casting and by chilling the melt to obtain shell hardening.

    摘要: The invention present disclosure relates to a refrigeration system for cooling the interior of a mobile refrigerated space, for example a refrigerated container, comprising two speed-controlled compressors, which can be operated in parallel as a single stage or one after the other as two stages by means of one controllable bypass line per compressor and a controllable valve device between the pressure side and the suction side of each compressor. The valve devices receive signals from a controller having algorithms, into which the usage temperature and ambient temperature are fed as a target value or measured value. The most energy-efficient operating modes and the rotational speeds of the compressors result from the requirements profile of the container refrigeration.
