<p>PROBLEM TO BE SOLVED: To provide an indoor machine capable of quickly detecting refrigerant leakage from a heat exchanger or the like due to long-term deterioration.SOLUTION: An indoor machine 1 includes a casing 2, a heat exchanger 3, a control unit 5, a detection sensor 6, and a power supply unit 9. The control unit 5 has an integration section and an activation interval change section. The integration section integrates electrification time electrified to the power supply unit 9. The activation interval change section makes an activation interval of the detection sensor 6 smaller as electrification time integrated by the integration section becomes larger.</p> |
