AIR-CONDITIONING APPARATUS

摘要

An air-conditioning apparatus includes an outdoor unit equipped with an outdoor-side heat exchanger formed by inserting a plurality of heat transfer pipes made of a metal material, such as aluminum or an aluminum alloy, into a plurality of fins, and an indoor unit equipped with an indoor-side heat exchanger formed by inserting a plurality of heat transfer pipes made of a metal material, such as aluminum or an aluminum alloy, into a plurality of fins. The heat transfer pipes in the outdoor-side heat exchanger are each internally provided with a plurality of straight grooves substantially parallel to the pipe axial direction. The heat transfer pipes in the indoor-side heat exchanger are each internally provided with a plurality of spiral grooves having a predetermined lead angle.
