摘要： A heat pump system includes a heat pump circuit, a load distribution element, and a controller. The heat pump circuit includes low-stage and high-stage compression mechanisms having a fixed capacity ratio relationship. The load distribution element establishes a load distribution between first and second heat loads subjected to heating processes by heat exchange with refrigerant discharged from the low-stage and high-stage compression mechanisms, respectively. The controller performs distribution control to maintain a ratio of 1 between temperatures of the refrigerant discharged from the low-stage and high stage compression mechanisms and after heat exchange with the first and second heat loads, respectively. Alternatively, the controller performs distribution control to reduce a difference between the temperatures of the refrigerant discharged from the low-stage and high stage compression mechanisms and after heat exchange with the first and second heat loads, respectively.

摘要： A heat pump system includes a heat pump circuit, a heat load circuit, first and second heat exchangers, a flow rate regulation mechanism and a controller. A first passage connects branching and converging portions of the heat load circuit. A second passage connects the branching and converging portions without converging with the first passage. The first and second heat exchanger perform heat exchange between discharge refrigerant from the low and high stage compression mechanisms and fluid in the first and second passages, respectively. The flow rate regulation mechanism regulates a ratio between flow rates through the first and second passages. The controller controls the flow rate regulation mechanism so that the fluid is allowed to flow to the first heat exchanger when a temperature of refrigerant flowing into the first heat exchanger is lower than a heating target temperature of converged fluid flowing through the heat load circuit.

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.

摘要： A refrigeration apparatus uses a refrigerant that operates in a region including critical processes, and includes a compression mechanism having first and second compressors, a heat-source-side heat exchanger, an expansion mechanism, a utilization-side heat exchanger, an intercooler, and an intermediate refrigerant pipe. The first compressor has a first low-pressure compression element and a first high-pressure compression element to increase pressure of refrigerant more than the first low-pressure compression element. The second compressor has a second low-pressure compression element and a second high-pressure compression element to increase pressure of refrigerant more than the second low-pressure compression element. The intermediate refrigerant pipe causes refrigerant discharged by the first and second low-pressure compression elements to pass through the intercooler and be sucked into first and second high-pressure the compression elements. The intake sides of the first and second low-pressure compression elements are connected. The discharge sides of the first and second high-pressure compression elements merge.
