Abstract

See full text

A refrigeration cycle device includes a heat source, a first use unit, a second use unit, a first connection flow path, and a second connection flow path. The heat source has a compressor and a heat-source side heat exchanger. The first use unit is separated from the heat source unit and has a first use-side heat exchanger. The second use unit is separated from the heat source unit and has a second use-side heat exchanger. The first connection flow path connects the heat source unit to the first and the second use units and causes a first refrigerant to flow. The second connection flow path connects the heat source unit to the first and the second use units and causes a second refrigerant to flow. A specific enthalpy of the second refrigerant is smaller than a specific enthalpy of the first refrigerant.
