The branch pipe branches from a third refrigerant pipe for connecting the radiator and the second expansion mechanism, and merges with the second refrigerant pipe. A third expansion mechanism is provided to the branch pipe.

摘要： A refrigeration apparatus uses a refrigerant that operates in a supercritical range. The refrigeration apparatus includes a compression mechanism, a heat source-side heat exchanger, an expansion mechanism, a usage-side heat exchanger, a switching mechanism, an intercooler, a bypass tube, and an injection tube. The switching mechanism is configured to switch between cooling and heating operation states. When the switching mechanism is switched to the cooling operation state to allow refrigerant to flow to the heat source-side heat exchanger and a reverse cycle defrosting operation for defrosting the heat source-side heat exchanger is performed, the refrigerant is caused to flow to the heat source-side heat exchanger, the intercooler and the injection tube. After the defrosting of the intercooler is detected as being complete, the bypass tube is used so as to ensure that the refrigerant does not flow to the intercooler and the injection valve is controlled so that the opening degree is increased.

摘要： A refrigeration apparatus includes a multi-stage compression mechanism, heat source-side and usage side heat exchangers each operable as a radiator/evaporator, a switching mechanism switchable between cooling and heating operation states, a second-stage injection tube, an intermediate heat exchanger and an intermediate heat exchanger bypass tube. The intermediate heat exchanger bypass tube ensures that refrigerant discharged from the first-stage compression element and drawn into the second-stage compression element is not cooled by the intermediate heat exchanger during a heating operation. Injection rate optimization controls a flow rate of refrigerant returned to the second-stage compression element through the second-stage injection tube so that an injection ratio is greater during the heating operation than during a cooling operation. The injection ratio is a ratio of flow rate of the refrigerant returned to the second-stage compression element through the second-stage injection tube relative to flow rate of the refrigerant discharged from the compression mechanism.
