Warmer Alpine Winters May Help Heat Pumps, but Start-Stop Losses Still Drag Performance
Italian researchers modeling air-to-water heat pumps in Alpine climates found that rising temperatures can modestly reduce defrost losses, but frequent start-up cycling remains a stubborn efficiency penalty.
Key Takeaways
- Italian researchers modeled PV-linked air-to-water heat pumps in Alpine regions under current and future climate conditions.
- Warmer temperatures modestly reduced efficiency losses associated with defrost cycles.
