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
