USER-SIDE AIR CONDITIONING DEVICE AND AIR CONDITIONING DEVICE COMPRISING SAME

摘要

A usage-side air-conditioning apparatus (3a, 3b) has: a casing (31a, 31b); a usage-side heat exchanger (33a, 33b) to cool or heat air inside the casing (31a, 31b) through the use of a refrigerant supplied from a heat-source-side air-conditioning apparatus (2); 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 (48a, 48b) to detect the refrigerant. When the refrigerant leakage detection device (48a, 48b) 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 (31a, 31b).
