The invention relates to a system in which a specified quantity of gas flows through the gas pressure reactor by means of pulse transfer. The work necessary for this is only required for overcoming the frictional resistance. The state quantities of the system are quasi-static. The state quantity potential energy, converted into kinetic energy, dissipates the energy in the fluid by friction via the quasi-static compression working pressure, said energy being supplied to a use as irreversible entropy with the heat flow transported by the heat exchanger. Formula (I) is regarded as a special form of the law of conservation of energy. The state change of the phase in an alternate direction of flow is assumed as being quasi-static. When the gas pressure reactor is flown through, the specific entropy s of the fluid changes between the inlet and outlet and attains the value s + ds. Entropy and enthalpy are determined with the aid of the thermal state equation (formula (II)). Indices 1 and 2 denote the control space of the pressure reservoir with a balance region of the gas pressure reactor between a and b.
