Abstract (en)

[origin: EP3115730A1] Provided is a refrigeration cycle apparatus, including a load-side heat exchanger (15) and a heat source-side heat exchanger (13) each including tubes with inner grooves, each of the tubes having inner grooves (23) extending obliquely with respect to a direction of a tube axis, and inner fins (24) each being formed between the inner grooves (23). In the refrigeration cycle apparatus, at least two of a first relationship, a second relationship, and a third relationship are satisfied: the first relationship of ±1>±2; the second relationship of H1>H2; and the third relationship of ¸1 <¸2, where ±1 and ±2 represent lead angles of the inner grooves (23) of the load-side heat exchanger (15) and the heat source-side heat exchanger (13), respectively, H1 and H2 represent heights of the inner fins (24) of the load-side heat exchanger (15) and the heat source-side heat exchanger (13), respectively, and ¸1 and ¸2 represent apex angles of the inner fins (24) of the load-side heat exchanger (15) and the heat source-side heat exchanger (13), respectively.
