Abstract: A device for climate control of an interior space includes comprising a heating and/or air-conditioning device fitted with a flow channel for an air current that is to be conditioned. On the inlet side there is an evaporator in the flow channel, and there is a first heat exchanger and a second heat exchanger in the flow channel downstream from said evaporator. The first heat exchanger is configured as a fuel-powered air-air heat exchanger. In addition, a method for climate control of an interior space using the heating and/or air-conditioning device.
