Abstract

A method is disclosed of absorbing heat for subsequent re-use from a thermal source comprising: passing a high pressure stream of a working fluid through or close to the thermal source so as to absorb heat from the thermal source, thereby producing a higher temperature stream comprising a liquid component and a vapour component; and separating the vapour component from the liquid component; wherein the working fluid comprises a lubricant (for example EMKARATE RL 32H), in which a natural refrigerant (eg carbon dioxide) is dissolved. The thermal source may have a temperature of no more than 150°C, and optionally 40°C or more.
