A method and a device for operating a heating and cooling machine, in particular a Vuilleumier heat pump, that functions on the basis of a regenerative gas cyclic process are described. The device includes a burner as the source of thermal driving, energy in which, to increase its efficiency or to maximize an output number of the heating and cooling machine, the combustion air conveyed to the burner is preheated in a heat exchange with exhaust gases. It is proposed that, for increasing the output performance of the heating and cooling machine, the preheating of the combustion air is forestalled at least partially. In response to a simultaneous increase of the burner output, the hot exhaust-gas mass-flow is conveyed to an exhaust-gas-water heat-exchanger.In this manner, a output of the heating and cooling machine system is increased in an advantageous manner, without having to change the design data or the size of the heating and cooling machine. |
