1.3 Feature
(1) Extensive application
With the airow ranging from 300 to 1900 m3/h and cooling capacity of 1.4 to 10.1kW, the FCU provides
three air speed settings to satisify users.
(2) High quality and reliability
Good materials and strict technical processing ensure high quality and normal service life of units.
(3) Low noise
In terms of dynamics, the optimized proportion of fan blade angle to impeller inner and outer diameters
improves airow and reduces noises.
(4) Lightweight and compactness
With aesthetic appeal, the unit is only 230mm thick, thus saving installation space.
The decoration panels have a curved surface presenting much thinness visually, which makes the unit
harmonize with any interior.
A track-like design of the top and the margin between castings and sheet metals increase its
uniqueness in appearance.
The color of castings on the top and bottom could be changed in accordance with clients’ needs.
(5) Intelligent control
The control system through micro-computer programs is connected with its thermostat that has a LCD
touch screen displaying many functions such as the cooling mode, heating mode, fan mode, timer and
child lock.
1.4 Working principle
The chilled (or hot) water go in the fan coil and make heat exchange with the indoor circulated air
(outdoor air), to realize cooling(heating), dehumidifying, ltrating or purifying. The processed air will be
supplied to indoor directly or by air duct.

Notes:
(a) Nominal cooling conditions: indoor dry/wet bulb temperature of 27/19°C, entering and leaving water
temperature of 7/12°C. Nominal heating conditions: indoor dry bulb temperature of 20°C, indoor
wet bulb temperature of no more than 15°C, enteringwater temperature of 45°C and leaving water
temperature of 40°C .
(b) The sound level is tested under the semi-anechoic chamber and the actual value will change under
different conditions.
(c) When conditions are out of the range, please contact GREE.
