Information

Data record for performance data that describe the normalized temperature difference versus the change in the rate of heating or cooling. The normalized temperature difference is defined as

r_ΔTⁱ= ΔTⁱ ⁄ ΔT_nominal = (T_wⁱ-T_z) ⁄ (T_w,nominal-T_z),

where T_wⁱ is the water inlet temperature, T_z is the zone air temperature and T_w,nominal is the nominal water inlet temperature.

The normalized temperature difference r_ΔT must be strictly increasing, i.e., r_ΔTⁱ < r_ΔTⁱ⁺¹. Both vectors, r_ΔT and f must have the same size.
