Abstract
This air conditioning device, in which an outdoor unit provided with a compressor and an indoor unit provided with an expansion valve are connected through a refrigerant pipe, is provided with: a first opening/closing valve provided on a refrigerant inlet side of the indoor unit; a second opening/closing unit provided on a refrigerant outlet side of the indoor unit; a state detection means which detects the state, inside the refrigerant pipe, between the first opening/closing valve and the second opening/closing valve; and a control device which controls the first opening/closing valve and the second opening/closing valve. The control device detects a leak of the refrigerant between the first opening/closing valve and the second opening/closing valve on the basis of the state detected by the state detection means when the first opening/closing valve and the second opening/closing valve are closed.
