Notes:
1.Cooling/Heating capacity, water flow rate, water resistance, and noise parameters are all based on ultra-high speed mode.
2.Cooling test conditions: Air inlet DB/WB = 27/19.5℃, chilled water supply/return = 7/12℃; Heating test conditions: Air inlet DB = 21℃, WB ≤15℃, hot water supply/return = 60/45℃, water flow rate same as cooling condition.
3.Rated air volume is measured under standard air conditions with coil dry condition (DB:20℃).
4.The unit noise level is tested in a semi-anechoic room with rear return air box, without filter, in accordance with GB/T19232-2019.
5.Sound pressure is a noise level model designed to meet cooling capacity requirements.
