Pascal rolled out a heat‑pump prototype that swaps traditional metal fins for a porous, sponge‑like absorbent. The startup says the material lifts the system’s coefficient of performance by roughly 20%.

The claim comes with a full‑scale test plan and a partnership with an unnamed HVAC manufacturer. Pascal’s engineers highlighted the material’s ability to store and release thermal energy more evenly than conventional …

A different kind of heat‑exchange surface

Conventional heat pumps rely on metal plates or fin arrays to move heat between a refrigerant loop and indoor air. Those surfaces conduct heat quickly but also suffer from uneven flow and pressure drops. Pascal’s spon…
