Abstract (en)

[origin: DE19904923A1] The invention relates to a heating and refrigerating machine, especially a Vuilleumier heat pump or a Stirling engine, in which a gas-air mixture is combusted in a combustion chamber and the exhaust gas radiates thermal energy to the heating head serving as a housing for the hot piston of the engine which forms a portion of the combustion chamber with a part of the outer surface thereof. By virtue of a porous burner and of the adaptation thereof to the heating head, the transmission of heat by means of convection and radiation is improved and a compact machine construction is attained which transmits heat in a highly efficient manner with low pollutant values over a broad modulation range of output.
