Abstract

An air-conditioning apparatus includes an injection pipe allowing a part of a refrigerant, as discharged from a compressing device, to flow into an intermediate portion of a compression stroke of the compressing device, and an injection internal heat exchanger that exchanges heat between a refrigerant stream that flows through the injection pipe and a refrigerant stream that flows into a heat-source-side heat exchanger after passing through an indoor unit.
