Abstract
Energy saving of a refrigerating cycle device is achieved by equalizing heat-medium inlet temperatures of a plurality of use-side heat exchangers. There are provided with a plurality of use-side heat exchangers, inter-heat-medium heat exchangers, a channel that connects the inter-heat-medium heat exchanger and the use-side heat exchanger, a heat-medium circulation circuit having heat-medium channel switching devices that switch between a first heat-medium channel, which connects the inter-heat-medium heat exchanger and the use-side heat exchanger, and a second heat-medium channel, which connects the inter-heat-medium heat exchanger and the use-side heat exchanger, and a heat source unit that heats or cools the heat medium with the inter-heat-medium heat exchangers, in which an auxiliary heat exchanger that performs heat exchange between the heat mediums flowing out from the inter-heat-medium heat exchangers is disposed so as to equalize the heat-medium temperatures flowing into the use-side heat exchangers to realize energy saving of the refrigerating cycle device.
