Patent ID: 7827820

Claim:
A thermodynamic machine for absorption and emission of heat at different temperatures, the thermodynamic machine comprising: at least one thermodynamic device comprising at least one membrane separating a gas phase and a liquid phase provided for transport of heat, respectively, wherein the at least one membrane is permeable for at least one component contained in the gas and liquid phases and wherein the gas phase and the liquid phase are circulated in a common closed circuit and are separated by the at least one membrane; wherein the at least one membrane is a porous membrane or a solution diffusion membrane; wherein the at least one thermodynamic device has a heat exchanger for supplying heat to or removing heat from one of the gas and liquid phases and wherein the heat exchanger is arranged inside the at least one thermodynamic device; wherein the at least one membrane is comprised of hollow fiber membranes combined to bundles or stacks in order to generate high surface density, wherein spaces between the hollow fiber membranes in the bundles or stacks are sealed relative to each other.
