requested operating points:
Depending on the HP categories covered by the application (heating and reversible if appropriate, swimming
pools), the requested operating points shall be detailed in the data and characteristics tables given in § 4 below.
Starting point at -15°C:
For Outdoor Air – Water type heat pumps, an HP starting point must be carried out to validate the operating range.
To enable the laboratory to conduct the test, we ask that you specify below the maximum water temperature, for
an outdoor temperature of -15°C. This value will be restated on the NF mark admission decision for the range.
Maximum water temperature = ………… °C
Specific information about "swimming pool" HPs (to be completed if covered by the application)
Water flow in the swimming pool exchanger (tick the relevant box):
Low flow (temperature condition 26 - 31°C - ΔT = 5°K)
High flow (temperature condition 26 - 28°C - ΔT = 2°K)
Use requested for Air/Swimming pool water type HPs (tick the relevant box).
Seasonal use (2 test conditions: 7°C and 15°C Air)
Year-round use (3 test conditions: 2°C, 7°C and 15°C Air)
