Frequently Asked Questions (4)

  • How does the Samsung CNH NDB Series heat pump provide heating and cooling?

    The Samsung CNH NDB Series heat pump provides cooling by pushing air through 15,000 micro holes in the panel, creating a dispersed and gentle flow of "still air". The unit is also capable of providing warmth in temperatures as low as -20°C, indicating its heating capability. The unit supports both Cooling Only and Heat Pump modes.


    For more information, see pages 3, 4, 5 and 7 of the manual.
