Abstract: The present invention relates to a gas heat pump and a control method therefor and, according to the present invention, the method for controlling a gas heat pump, which comprises an ignition plug and a gas engine having an engine combustion unit including a plurality of combustion spaces, may include: a target setting step of setting a target ignition energy amount on the basis of a refrigerant load amount determined according to a driving condition of the gas heat pump; an ignition step of igniting fuel injected into the combustion spaces; a comparison step of comparing an output energy amount emitted in the ignition step with a target ignition energy amount set in the target setting step; and a step of changing an energy amount required to ignite the fuel when the output energy amount and the target ignition energy amount do not coincide in the comparison step.
