Page 8: How Split Systems Work
The outdoor air is routed through the outdoor unit by means of a fan. The indoor and outdoor units are connected through refrigerant lines. Due to the defrosting mode integrated into OCHSNER air/ water heat pumps, the system also operates flawlessly at temperatures below -15°C. - Page 9 How split systems work 00_400_200_202_01_split_Funktionsweise_EN | www.ochsner.com...
