  • Compressor service tool
    Patent number: 8745865
    Abstract: In a method for servicing an apparatus having a compressor (22) mounted to a support structure (32, 38, 40), a guide structure (102, 104; 202, 204) is placed adjacent to the support structure. The compressor is lifted from an installed position. The compressor is withdrawn by rolling the compressor along the support structure and guide structure.
    Type: Grant

  • Refrigerating system with economizing cycle
    Patent number: 7654109
    Abstract: The invention relates to refrigerating systems, primarily, to refrigerating systems employing compressors with economizing inlets and multi-pass condensers. In accordance with the invention a refrigerating system with economizing cycle employs a compressor unit with an economizer inlet and a condenser unit having a first condensation stage, a second condensation stage, and means to remove liquid refrigerant portion between the condensation stages. An intermediate liquid outlet from the first condensation stage feeds a circuit with the evaporator and a liquid outlet from the second condensation stage feeds a circuit with the economizer inlet. The invention provides a high efficiency refrigerating system incorporating of advantages of cost-effectiveness provision of liquid sub-cooling or/and liquid temperature inherent for refrigerating systems with economizing cycle and cost-effectiveness advantages of two-stage condensation condensers.
