Heating mode (2-pipe coil): entering air temperature 20°C, entering water temperature 50°C, high fan speed, same water flow rate as in cooling mode. Heating mode (4-pipe coil): entering air temperature 20°C, entering water temperature 70°C, high fan speed, water temperature difference = 10 K. Based on a hypothetical acoustic attenuation for the room and the air distribution system of -9 dB(A). 624 C A R R I E R 2 0 1 6 / 2 0 1 7
