Flow Rate - Samsung EHS AE050RXYDEG/EU Manual

Flow rate

The heat pump delivers its rated capacity at exactly the designed flow rate (also standard or nominal flow). Therefore it is
required to always meet with the designed flow rate as indicated in our product specifications. The installer is responsible
to meet with the exact designed flow rate (Water Flow Rate (Std)[H/C], as stated in the applicable TDB).
• In case the flow is too high, it should be balanced out by increasing the pressure drop of a balancing (or flow regulator)
valve.
• If the flow is too low, an additional pump must be installed to assist the built-in pump.
The control logic for the PWM pump can adjust the flow between 50% and 100% of the standard flow to meet with the
required temperature differences in the heating and cooling processes.

If the flow rate is too low, the generated heat might not meet with the designed capacity.
If the flow rate is too high, it may cause noise, cavitation and erosion and impact the efficiency of the product.
