1.3 Product Features
1.3.1 Features
FCU is the most widely used terminal unit of the air conditioning system, used fo supplying cooling
(hot) water, with the air flow below 2500m3/h and the external static pressure less than 100Pa. For
cooling, enthalpy loss of the air generally is 15.9kJ/kg. For hot water under 60℃, the cheating capacity is
1.5 times of the cooling capacity.
As the terminal unit of the central air conditioning system, it is widely used in public areas with the
following main features:
a. Three speeds are selectable for the air flow. According to the set point of the room temperature,
the water system can be controlled by the hot/cool water automatic regulating valve so that
temperature for each room can be controlled separately for meeting different requirements.
Where no one is inside the room, it can be turned off manually or by the timing function, which
will lower the operation cost of the whole system.
b. The zone control is available based on direction, height, utilization and service time, which can
avoid unreasonable conceptualized control of the large-sized duct system.
c. Compact structure, flexible arrangement, and easy installation will save installation space and
facilitate indoor decoration.
There are various structures with the same air flow and cooling capacity for different room structure,
different decoration and duct arrangement.
(1) Plastic Fan
a. Light-weighted, which will lead to increased air flow driven by the same motor.
b. Good compatibility of the angle of the blades and the cavity of the volute, which will lead to silent
operation.
c. CFD designed flow and angle of fan blades, for high operation efficiency
d. The volute is divided into the upper and lower parts, which will facilitate disassembly.
(2) CFD Designed Fan
a. Optimized flow structure
b. Evenly distributed air flow and low flow noise
c. less eddy flow
d. Novel style and advanced structure
e. Decreased height , saving installation space
f. Low noise and three fan speeds
g. High-quality material and strict processing control for guaranteeing quality and service life of
the whole unit.
h. Die formed drain pan with the entirely pressured and pasted insulation, generating no

Enginnering Data
12
condensate
i. Optimized location of the exhaust and drain valves, for better heat exchanging effect and
preventing from frost cracks in winter.
(3) High-efficiency copper tubes
The copper tubes are made of pure red copper with female threads on the inner wall. There are also
raised teeth at the inner wall, used for increasing turbulent flows and damaging the boundary layer of
water for better heat exchanging capacity.
(4) The Cooler with the Interchangeable Left/Right Structure
During installation, the left-type and right-type structure can be selected flexibly as steps stated below:
Step 1: Remove the centrifugal fan, cover plate and screws of the electric box.
Step 2: Move the side plate at the air outlet to the other side.
Step 3: Rotate the fan assembly and the cover plate for 180°and then fix them.
Step 4: Remove the electric box to the other side and then fix it..
1.: Cover plate; 2. Centrifugal fan; 3. Side plate at the air outlet
Left-type Unit Right-type Unit
1.4 Working Principle
The cool (hot) water goes in the fan coil and makes heat exchanging with the indoor circulated air
(outdoor air), to realize cooling(heating), dehumidifying, filtrating or purifying. The processed air will be
supplied to indoor directly or by air duct.

Notes:a) The left and right modes can be switched over on site. The correction coefficient for both
cooling and heating is 0.9.
b) Nominal cooling conditions: (27/19.5℃) indoor dry/wet bulb temperature, (7/12℃) entering
and leaving water temperature. Nominal heating conditions: 21℃indoor dry bulb
temperature, 60℃entering water temperature.
c) The noise is tested under the semi-anechoic chamber and the actual value will change
under different environments.
