Working medium, useful for cooling- and heating processes and for operating e.g. absorption heat pump, comprises an ionic liquid as an absorbent comprising tetra(alkyl)ammonium cation and a cooling- or heating agent

摘要

Working medium comprise (a) at least one ionic liquid as an absorbent, which comprises at least one tetra(1-3C alkyl)ammonium cation and (b) at least one cooling- or heating agent. Independent claims are also included for: (1) operating an absorption heat pump, absorption refrigerator unit, absorption based heat transformer or a heat engine with the working medium; and (2) an absorption heat pump, absorption refrigerator unit, absorption based heat transformer or a heat engine with the working medium.
