Abstract
Proposed are a refrigeration cycle apparatus and a leakage inspection method for refrigerant piping of a refrigeration cycle apparatus, in both of which leakage inspection of joints of the refrigerant piping can be readily performed regardless of where the joints of the refrigerant piping are provided, including a space being hard-to approach, inaccessible, and extremely narrow. A refrigeration cycle apparatus includes: a plurality of pipe materials; refrigerant piping including a joint that joins the pipe materials by brazing or welding; and a piping cover that covers at least part of the refrigerant piping including the joint and has a leakage inspection port that allows a gas to flow out from the inside to the outside.
