Unit 1 Introduction closet fan coil fan coil air conditioning unit ① edit cabinet full sheet metal design, appearance, structure and smooth, light weight. ② panel of non-rigid contact with the frame, the process is good, with the close air leakage rate. ③ water tray with large drainage slope to ensure condensate discharge smoothly. ④ air filter easy accessibility, there are a variety of materials available. ⑤ structure forms, vertical, horizontal, ceiling mounted, ceiling mounted, and so thin. ⑥ have return air type and a new wind patterns, frequency conversion techniques may also be variable air volume control. ⑦ widely used in hotels, restaurants, factories, hospitals, airports, railway stations, exhibition halls, office buildings, shopping centers, laboratories and other central air conditioning system. Fan coil types of models designed to meet different occasions selection, wind and wall-mounted fan coil ## and a variety of fan coil embedded floor. In accordance with the national standard GB / T 19232-2003 "fan coil units," Part 4 classification, fan coil classified according to the following form: structure type horizontal, vertical (with column and low type), the card , wall, floor type. Mounting by distinct dark suits and put water into left-style orientation (facing the unit outlet for the return pipe on the left), the right type (face outlet unit for the return pipe on the right). Features fan coil fan coil delicate body structure, compact, durable, beautiful and noble and elegant appearance. Fan coil made of high quality galvanized chassis, condensate tray molding process using one piece, no welds, joints, insulation materials meet the fire code is integrally connected to the water dish. Fan coil is small, lightweight body design. Sewer line installation and simple way around to take over and return air can be converted at any time to meet the situation. Fan coil high efficiency, advanced expanding technology to ensure close contact brass and aluminum heat exchanger, the heat transfer performance; low noise fan coil, fan and airflow reasonable structure design, high-quality acoustic insulation materials, the unit noise below the national standard 1-3dB (A); fan coil low energy consumption, a reasonable match fan and heat exchanger, Three adjustable air flow, the fan power of the most power.
