Refrigerating cycle device used in an air conditioning apparatus, a refrigerating device and the like

A refrigerating cycle device comprising:

• a plurality of use-side heat exchangers;
• a first inter-heat-medium heat exchanger having one port connected to each heat-medium inlet of the use-side heat exchangers by a pipeline and the other port connected to each heat-medium outlet of the use-side heat exchangers;
• a second inter-heat-medium heat exchanger having one port connected to each heat-medium inlet of the use-side heat exchangers by a pipeline and the other port connected to each heat-medium outlet of the use-side heat exchangers;
• a plurality of first heat-medium channel switching devices, each of which is disposed on the heat-medium inflow side of each of the use-side heat exchangers, switching between a first inflow-side channel, which connects the first inter-heat-medium heat exchanger and the heat-medium inlets of the use-side heat exchangers, and a second inflow-side channel, which connects the second inter-heat-medium heat exchanger and the heat-medium inlets of the use-side heat exchangers;
• a plurality of second heat-medium channel switching devices, each of which is disposed on the heat-medium outflow side of each of the use-side heat exchangers, switching between a first outflow-side channel, which connects the first inter-heat-medium heat exchanger and the heat-medium outlets of the use-side heat exchangers, and a second outflow-side channel, which connects the second inter-heat-medium heat exchanger and the heat-medium outlets of the use-side heat exchangers;
• a heat source device that is connected to the first inter-heat-medium heat exchanger and the second inter-heat-medium heat exchanger and supplies heating energy or cooling energy to the first inter-heat-medium heat exchanger and the second inter-heat-medium heat exchanger so as to heat or cool a first heat medium flowing from the first inter-heat-medium heat exchanger to the use-side heat exchangers and a second heat medium flowing from the second inter-heat-medium heat exchanger to the use-side heat exchangers;
• an auxiliary heat exchanger having a first heat-medium inlet which is connected to the first inter-heat-medium heat exchanger by a pipeline and which the first heat medium flows into, a first heat-medium outlet which allows the first heat medium having flowed in from the first heat-medium inlet to flow out to the use-side heat exchangers through the plurality of first heat-medium channel switching devices, a second heat-medium inlet which is connected to the second inter-heat-medium heat exchanger by a pipeline and which the second heat medium flows into, and a second heat-medium outlet which allows the second heat medium having flowed in from the second heat-medium inlet to flow out to the use-side heat exchangers through a plurality of the first heat-medium channel switching devices, and performing heat between the first heat medium flowing from the first heat-medium inlet to the first heat-medium outlet and the second heat medium flowing from the second heat-medium inlet to the second heat-medium outlet through a heat transfer material or performing heat exchange by mixing the first heat medium flowing in from the first heat-medium inlet and the second heat medium flowing in from the second heat-medium inlet and allowing the mixture to flow out of the first heat-medium outlet and the second heat-medium outlet;
• and
• a heat-medium channel that connects a bypass pipeline that bypasses the auxiliary heat exchanger and an opening/closing valve disposed in the bypass pipeline to the heat-medium outlet of either the first inter-heat-medium heat exchanger or the second inter-heat-medium heat exchanger that the heat medium flows out from.
