Abstract
The present invention provides: a control device that can improve energy efficiency; a cut-off valve circuit device provided with the control device; an air-conditioning device provided with the control device; and a control method. This control device (40) is provided with: a power storage unit (27) that is charged by an external power source (22); and a control unit (21) that controls power supplied from the external power source or the power storage unit. If power is being supplied from the external power source and the amount of charge in the power storage unit is equal to or greater than a prescribed amount, the control unit uses the power charged in the power storage unit to control loads (EV, SV) connected to the outside.
