Abstract
A usage-side air-conditioning apparatus has: a casing; a usage-side heat exchanger to cool or heat air inside the casing through the use of a refrigerant supplied from a heat-source-side air-conditioning apparatus; an air supply/exhaust mechanism to take room air and/or outdoor air in from an air-conditioned space or outside of the air-conditioned space, supply the air as supply air to the air-conditioned space, and exhaust the air as exhaust air out of the air-conditioned space; and a refrigerant leakage detection device to detect the refrigerant. When the refrigerant leakage detection device has detected the refrigerant, a refrigerant exhaust operation is performed by the air supply/exhaust mechanism to exhaust the refrigerant out of the air-conditioned space along with the air inside the casing.
