<p>An object of the present invention is to reduce the detection error by correcting the judged refrigerant quantity. An air conditioner (1) is an air conditioner that performs a refrigerant quantity judging operation to judge the refrigerant quantity in a refrigerant circuit (10), and includes a heat source unit (2), utilization units (3a to 3c), expansion mechanisms (V2, V9a to V9c), a first refrigerant gas pipe (52), a second refrigerant gas pipe (53), a refrigerant liquid pipe (51), switching mechanisms (4a to 4c), temperature detecting means (T8, T12a to T12c), and a controller (8). The heat source unit includes a compression means (21) and a heat source side heat exchanger (22). The first refrigerant gas pipe is connected to the discharge side of the compression means. The switching mechanism can switch between a first state and a second state. The temperature detecting means are mounted on the first refrigerant gas pipe, and configured to detect a refrigerant temperature on the first refrigerant gas pipe side and output a refrigerant temperature detection value. The controller corrects the refrigerant quantity judged by a refrigerant quantity judging operation based on the refrigerant temperature detection value.</p> |
