In accordance with the national standard GB / T 19232-2003 "fan coil units," Part 4 classification, cassette fan coil wiring diagram, fan coil units classified according to the following form: structure type horizontal and vertical (with column type and low type), cassette, wall, floor type according to the installation type distinct dark suits and put water into left orientation of formula (facing the unit outlet for the return pipe on the left), the right formula (face unit outlet for return pipe on the right). Keao Nanjing Environmental Engineering Equipment Co., Ltd. is a professional committed to the central air-conditioning products R & D, manufacturing, sales and environmental engineering design, installation, technical advice of high-tech companies. After years of development, cassette fan coil motors, the company has become a central air conditioning system product variety, specifications of the most complete, most professional technology. Application Status of fan coil units: Due to fan coil system with easy-to-control, easy installation, low cost, so its applications continue to expand, product types are also increasing. When the traditional large centralized air-conditioning and split air conditioners are not home when the modern civilization to meet the living environment and living quality management requirements, the concept of residential central air conditioning emerged. Such as: air-cooled water chiller and fan coil modular, air-cooled water chiller and fan coil and floor heating combined with water (ground) source heat pump and fan coil modular, air-cooled chiller Combined with the domestic boiler and fan coil and so on. Currently, residential central air-conditioning is becoming China's real estate developers and owners to improve the quality real estate to improve the quality of living conditions. Winter freezing measures must be adopted to prevent the pipe cracking. Fan coil cold water inlet temperature, Luohe cassette fan coil, generally used 7 ℃ ~ 10 ℃, the cold water temperature take 5 ℃, water inlet temperature is generally used in 50 ℃ ~ 60 ℃, under possible conditions, should be Progress cold water inlet temperature and reduce hot water inlet temperature. Cassette fan coil supplier, Keao environment (online consultation), Jiaozuo cassette fan coil is provided by the Nanjing Environmental Engineering Equipment Co., Ltd. Keao. Keao Nanjing Environmental Engineering Equipment Co., Ltd. (www.njxfxt.com) is Nanjing, the other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
