Abstract

Provided is an air conditioner capable of accurately detecting a refrigerant leakage. An air conditioner (100) includes a refrigerant circuit (10) and a detector (61). The refrigerant circuit includes a heat source heat exchanger (23), an expansion valve (24), and a utilization heat exchanger (51), and is filled with a refrigerant. The detector detects a refrigerant leakage in the refrigerant circuit. The detector detects the refrigerant leakage by comparing a first value (P1) corresponding to a first estimated flow rate (F1) that is an estimated flow rate (F) of the refrigerant flowing through the expansion valve in a first term (T1) with a second value (P2) corresponding to a second estimated flow rate (F2) that is an estimated flow rate of the refrigerant flowing through the expansion valve in a second term (T2) before the first term.
