Session Beschreibung
Overview:
European heat pump demand is surging, driven by REPowerEU, national fossil fuel phase-outs, and end-user needs for lower heating costs. However, OEMs face challenges: maintaining seasonal efficiency (SCOP) at -15°C outdoor, achieving flow temperatures of 70–75°C without electrical backup, handling low-GWP flammable refrigerants, and meeting strict noise regulations for indoor and outdoor units.
Key Technical Focus Areas:
· Cold climate performance – Hitachi enhanced vapor injection (EVI) and wide-speed-range inverter scroll compressors maintain high heat output and COP down to -25°C ambient.
· High condensing temperature – New bearing and compliance me ...
