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.
