Abstract:
A method of manufacturing an air-conditioning apparatus serving as a refrigeration cycle apparatus includes: performing an operation test in a factory under a state in which inert gas (nitrogen) is sealed into respective devices mounted on an outdoor unit (such as a compressor and a four-way valve) and an outdoor pipe connecting the devices in place of refrigerant having flammability; and shipping the air-conditioning apparatus under the state in which the inert gas remains sealed.
