Abstract
A method for operating cyclic process-based systems, with a hot-side reservoir (1) and a cold-side reservoir (2) for a fluid (3), and at least one heat exchanger unit (4) with mechanocaloric material, wherein the mechanocaloric material of the heat exchanger unit (4) is actively connected to the fluid (3) such that heat is transferred between the mechanocaloric material and the fluid (3). It is essential that the transfer of heat between the mechanocaloric material and the fluid (3) takes place essentially by latent heat transfer. A corresponding heat-transfer unit (4) and a corresponding apparatus are also provided.
Claims16
A method for operating cyclic-process-based systems having a hot-side reservoir (1, 11, 21) and a cold-side reservoir (2, 12, 22) for a fluid (3) and at least one heat exchanger unit (4) with a mechanocaloric material, the cyclic-process-based system being a heat pump having at least two heat exchanger units (14.1, 14.2), including the at least one heat exchanger unit, the heat exchanger units having the mechanocaloric material, the method comprising:
- arranging the mechanocaloric material of the heat exchanger unit (4) to be operatively connected to the fluid (3) in a gas-tight fluid circuit, such that a heat transfer takes place between mechanocaloric material and fluid (3), transferring heat between mechanocaloric material and the fluid (3) substantially by latent heat transfer via evaporation heat and condensation heat of the fluid (3), and alternately opening and closing a hot-side valve (7, 17) and a cold-side valve (8, 18) with respect to one another.
