8. TECHNICAL DATA
(1)
ratio between the thermal gain of the inlet air (0 °C) and the thermal loss of the exhaust air (20 °C), both referred to the external temperature, measured under dry
reference conditions, with balanced mass flow and a thermal difference of the internal/external air of 20K, excluding the thermal gain generated by the fan motors and
the internal leakage, in accordance with the provisions of attached V of EU Regulation No 1253/2014
(2)
performance with clean filters
(3)
sound power level calculated in accordance with EN 3744
(4)
sound pressure level measured at 1 m free field distance, in accordance with EN 3744
