4.1.2. Coil
The coil used in the AHU models consists of a fin-tube heat exchanger for higher efficiency. The model-specific distribution
can ensure the even distributions of chilled water in each loop and improve the heat exchanger's efficiency significantly
apart from minimizing the water resistance of the heat. It also minimizes the water press drop. The coil has a hydrophilic
coating as standard.
4.1.3. EPIV
EPIV-Electronic Pressure Independent Valve. The water flow of the unit can be controlled very accurately, even if the water
pressure fluctuates, the water flow can be kept stable with EPIV. EPIV has the characteristics of high reliability, maintenance-
free, fast response, and direct flow control.
4.1.4. 9-inch Color Display
AHU is available with 9-inch touch screen as a standard display, using multi-color 800×480 dot-matrix liquid crystal touch
screen with white backlight as shown in
Figure
4-3. The operation of the unit becomes simpler and more convenient, and the
status view of the unit is more visualized.
