2 DESCRIPTION The FCU(A,F) fan coil unit is a highperformance, cost-effective and compact solution for the cooling of technical compartments on board vessels. The FCU(A,F) is the right solution where limited installation space and a cooling load exists. The three FCU(A,F) unit sizes cover an airflow range of m3/s and a cooling capacity range of 3 53 kw in the DX-coil variant and 2 45 kw in the chilled-water coil variant. Design The FCU(A,F) casing is of double-skin sheet steel design with intervening 25 mm thick mineral wool insulation. Galvanized sheet steel or stainless sheet steel of AISI 304 (SIS 2333) or AISI 316 (SIS 2343) quality can be selected. The large service covers are equipped with robust, easy-to-use handles; the covers can be lifted off the unit after they have been opened. The main components of the FCU(A,F) are installed in a common casing at the factory. This minimizes the installation work in ventilation systems and provides a compact design. The smooth surfaces inside the unit make the FCU(A,F) hygienic and easy to clean. Overall dimensions The FCU(A,F) has relatively small overall dimensions in terms of its capacity and the airflow that it generates. The three sizes of unit are 400, 450 and 500 mm high respectively; and 605, 5 and 805 mm wide respectively. The unit casing is 11 mm long and the base frame is 13 mm long in all three unit sizes. Thanks to its compact dimensions, the FCU(A,F) can easily be situated in all the relevant spaces. Installation options The FCU(A,F) should normally be installed suspended from a deck head or secured by means of bolts to the deck. The vertical variant of the FCUA is designed for bulkhead-mounting. Applications The FCU(A,F) fan coil unit is well-suited for chilling the surplus heat arising in technical compartments on board vessels. The unit uses % recirculated air. Fan The fan in the FCU(A,F) is a direct-driven, centrifugal fan with forward-curved impeller blades. This eliminates the drawbacks of belt-drive operation, such as the need for retensioning or replacing drive belts and capacity losses. The fan is isolated from the unit casing by means of antivibration mountings and a flexible duct. Therefore, the fan coil unit does not require any extra external insulation. Filter The FCU(A,F) is available with two types of filter. The FCUA has a Class EU3 flat filter with replaceable filter mat whereas the FCUF has a Class EU5 disposable bagtype filter. The filter and the droplet eliminator are split into two sections which reduces the amount of space beside the unit needed for servicing. Air cooler The air cooler is available in versions for type R22, R407C and R134A refrigerant as well as for chilled water. The coolers can be selected with copper tubes and aluminium or copper fins. All the types of air cooler are available in 4 capacity variants with 3, 4, 6 or 8 tube rows arranged in the direction of air flow. The chilled water coil (air cooler) has nipples for the installation of a purging valve and an anti-frosting protection sensor. A thermometer located downstream of the coil is included in the supply. Equipment/Accessories The following additional equipment/accessories for the FCU(A,F) are available: EUAZ-08 water trap for connection to the drain connection of the drip tray beneath the cooling coil EUAZ-21 expansion valves for the DX-cooler (R22, R407C, R134A) FCUZ replacement filters (EU3, EU5) 2
