See full text

A refrigerant cycle system includes: a primary-side cycle of a vapor compression type that circulates a first refrigerant; a secondary-side cycle of a vapor compression type that circulates a second refrigerant; and a cascade heat exchanger that exchanges heat between the first refrigerant and the second refrigerant. The secondary-side cycle includes a secondary-side heat exchanger that uses cold or heat obtained by the second refrigerant from the cascade heat exchanger. The secondary-side heat exchanger includes a flat multi-hole pipe.
