Abstract
Described herein is the use of organic materials in methods of barocaloric cooling. The barocaloric effects may be exhibited where the organic material is near a non-isochoric phase transition, such as a non-isochoric first-order phase transition. The organic material has one or more carbon atoms and may be an organic compound or a salt thereof. In some cases that organic material is a soft matter material, such as a plastic crystal or a liquid crystal. The methods may be adapted for use of the organic material as a heating agent.
Claims23
A method comprising employing an organic material as a barocaloric cooling or heating agent, wherein the method comprises:
- (i) applying hydrostatic pressure to an organic material;
- (ii) permitting heat flow from or to the organic material;
- (iii) releasing hydrostatic pressure from an organic material that is under applied pressure;
- and
- (iv) permitting heat flow to or from the organic material.
A method of barocaloric cooling or heating, the method comprising the steps of:
- (i) applying hydrostatic pressure to an organic material;
- (ii) permitting heat flow from or to the organic material;
- (iii) releasing hydrostatic pressure from an organic material that is under applied pressure;
- and
- (iv) permitting heat flow to or from the organic material.
A cooling or heating apparatus comprising an organic material as a barocaloric cooling or heating agent and a means for transferring heat to and from the organic material, wherein the means for transferring heat to and from the organic material is suitable to transfer heat for a barocaloric transition with a latent heat, |Q0|, that is at least 25 kJ kg−1.
