Main Features General The new ACW-D FCUs are specifically designed to satisfy high cooling capacity application requirement. They represent one of the most cost effective solutions to provide a comfortable environment for both commercial and residential applications. Their quiet operation, compact dimensions and particularly low height, make units ideal for ceiling concealed installation even in buildings with narrow ceiling spaces. Units are standard supplied with soundproofed suction plenum and air filter. Centrifugal fans, with forward-curved blades, are statically and dynamically balanced and driven by single-phase motors with three speeds.they feature elegant design, advanced structure, high efficiency, low noise, convenient installation and low maintenance. They are widely used in houses, shopping malls, hospitals and office etc. Higher Cooling Capacity in High Delta T Application These units are particularly suitable for high External Static Pressure and high Delta T(chilled water temperature difference) applications. They can delivery more cooling capacity in high Delta T conditions with the specially designed fans & motors, coils and excellent combination of them. Low Chilled Water Pressure Drop In order to meet even the most demanding customer requirements, the new FCUs adopt the most reasonable and optimization water circuit design and utilize the national level thermal test room to guarantee both the perfect performance and a low chilled water pressure drop. Extra High Air Flow Volume at High ESP These units can supply more air flow at high ESP. 10 models of ACW-D cover an air flow range from 340 to 2380CMH at medium speed with ESP of 75Pa in wet coil condition. Air Filter All units can provide up to one-inch thick washable filters. Filters are held by a removable metal strip and can be easily pulled out from the bottom for cleaning or replacement. High Efficiency Heat Exchanger A boundary layer film of air adhering to the fin surface will insulate the fin surface and severely reduces the heat exchange efficiency. ACSON slit fin design eliminates this boundary layer of air and creates continuous turbulence for best heat exchange efficiency. Flexibility Units are available with left or right hand water connections, which can be easily switched in the field by changing the positions of the fan-motor assembly and the supply air flange assembly if required. Compact Design The low height design makes this fan coil unit series ideally suited for the tight ceiling concealed installation Low Noise Design Enlarged fan wheels design allows lower fan RPM selection for the same external static pressure and airflow requirement. Thereby noise level is significantly reduced. 2 ACWD_2006.indd 2 2006-5-25 17:24:42

Guide Specifications Unit Description Factory-assembled, horizontal, blow-thru type, galvanized casing, ceiling ducted fan coil unit is complete with water coil, fans, motors, drain pan, filters and all required wiring, with full access to internal components. Quality Assurance Each coil is factory tested for leakage at 3.3MPa air pressure with coil submerged in water. Each unit and its moving components (fans and motors) are factory computer-tested and recorded after unit is complete and before it is packed. Component Specifications 1.Casing Construction is of 0.8mm thickness galvanized steel, lined on the inside with 5mm PE thermal and acoustical insulation. Return air plenum is lined with 5mm PE foam and has a 20mm collar for return duct connection. Supply duct connection also has a 20mm long collar. Removable bottom panel is provided for access to the fan/motor assembly. 2. Coil Standard unit is equipped with a 4-row coil for installation in a 2-pipe system. Coil has 3/8 inch seamless copper tubes, slit type aluminum blue fins bonded to the tubes by mechanical expansion. Each coil has a manual air vent and two Rc3/4 water pipe connections with a working pressure of 1.6MPa. 3. Fan Direct-driven centrifugal fan wheel has forward-curved blades which are statically and dynamically balanced. The fan housing and blades are constructed of high quality hot-galvanizing steel. 4.Motor Fan motor is 3-speed, 220V-240V, single-phase, 50Hz, permanent split-capacitor type with ball type bearing and build-in automatic reset thermal overload protection. The motor s insulation is class B. 5. Drain pan The drain pan plate body is constructed of cold-rolled steel by way of integral cupping. Both its sides are sprayed with plastic coating. And its outer wall is lined with 6mm heat insulating PE foam and high quality adhesive by way of integral adhering and pressing. It extends under the full length and width of the coils and is pitched for positive drainage with features of high anti-corrosion, anti-condensation and high fire reluctance. 6. Filter Filter is with washable type double-layer nylon media in 25mm thickness aluminum frame. 11 ACWD_2006.indd 11 2006-5-25 17:24:50
