Air Conditioner

Abstract: The objective of the present invention is to provide a heat exchanger with which the heat exchange performance of an indoor heat exchanger can be increased and the efficiency of an air conditioner can be improved without increasing pressure loss in the pipes of an outdoor heat exchanger. The present invention is equipped with: an outdoor unit in which is mounted an outdoor heat exchanger (3) formed by inserting through multiple fins (12) multiple heat transfer pipes (23) formed with a metal material such as aluminum or an aluminum alloy; and an indoor unit in which is mounted an indoor heat exchanger (2) formed by inserting through multiple fins (11) multiple heat transfer pipes (21) formed with a metal material such as aluminum or an aluminum alloy. Multiple straight grooves (24) are formed substantially parallel to the axial direction of the pipe on the inside of the heat transfer pipes (23) of the outdoor heat exchanger (3) and multiple spiral grooves (22) having a prescribed lead angle are formed on the inside of the heat transfer pipes (21) of the indoor heat exchanger (2).
