PROBLEM TO BE SOLVED: To ensure an optimum fuel injection amount and prevent an outdoor unit from stopping operating even if an engine is driven in a state of opening a maintenance/inspection door or a state of detaching a panel.SOLUTION: An open/close detection sensor 13 or 14 detecting an open/closed state of at least either a maintenance/inspection door 11 or a panel 12 and transmitting an open/close signal to a control unit (ECU) 5 is provided in a casing 2. The control unit (ECU) 5 stores therein in advance an open-time control map for calculating an optimum fuel injection amount from a relation between an engine rotational speed and an inlet air supply amount in response to an inlet air amount of an engine 1 within the casing 2 when either the maintenance/inspection door 11 or the panel 12 is opened. If the open/close signal transmitted from the open/close detection sensor 13 or 14 is an open signal, the control unit (ECU) 5 switches a control based on a normal operation control map to a control based on the open-time control map to control the engine 1 to operate. |
