Barocaloric cooling and heating.

Number: 572

Author(s) : ROSE R., LAWTON R., MOYA X.

Summary

Barocaloric effects are nominally reversible thermal changes that occur in mechanically responsive materials when subjected to changes in hydrostatic pressure. These effects are analogous to the pressure-induced thermal changes in fluids that are exploited in current refrigerators, air-conditioners and heat pumps, but they promise higher energy efficiencies and obviate the need for ozone-depleting and greenhouse gases. Barocal Limited has recently designed and built the first proof-of-principle prototype barocaloric cooling and heating system, which is capable of delivering external cooling and heating of more than 5°C. This proof-of-principle prototype exploits a solid organic barocaloric material that displays colossal barocaloric effects under moderate applied pressures of 150 MPa.
