AIR CONDITIONER

To solve a problem of a conventional air conditioner performing risk avoidance operation at detection of a refrigerant that there is a possibility of performing the operation when there is no leakage, which causes maintenance cost and deterioration in convenience.SOLUTION: An air conditioner includes first refrigerant shut-off means, second refrigerant shut-off means, state detecting means for estimating a state of a refrigerant in an indoor unit, and refrigerant detecting means. When the refrigerant detecting means detects the refrigerant, detection of the refrigerant is notified by notifying means, refrigerant recovery operation is performed, and refrigerant leakage detection processing is performed so as to determine presence/absence of the leakage of the refrigerant, and unnecessary maintenance can be dispensed with by performing suitable operation and action. Thereby, it is possible to provide the air conditioner environmentally-friendly, having high safety and reliability, and excellent in convenience.SELECTED DRAWING: Figure 1 【課題】従来、冷媒検知から危険回避動作を行う空気調和機では、漏洩がない場合に動作し、メンテナンス費用の発生や、利便性の悪化をまねく可能性があった。【解決手段】 第１冷媒遮断手段と、第２冷媒遮断手段と、室内機の冷媒状態推定のための状態検知手段と、冷媒検知手段を備え、冷媒検知手段が冷媒を検知した場合、告知手段により冷媒検知を告知し、冷媒回収運転を行い、冷媒漏洩の有無を判定する冷媒漏洩判定処理し、適切な運転、動作を行うことで、不要なメンテナンスなどをなくし、環境負荷が小さく、高い安全性と信頼性を有し、利便性の高い空気調和機を提供する。【選択図】 図１
