With the rapid development of intelligent buildings, the importance of FCU (fan coil unit) system electric valves as the "peripheral nerves" and "final executors" of building automation systems is increasing day by day. Hengsen FCU system electric valves: DDF and DRF series electric valves are the key equipment for achieving precise fluid control in building automation systems as the core execution units of intelligent buildings. They protect the comfort and safety of buildings. Behind the seemingly simple opening and closing actions are the research and development results of Hengsen Group's technical team.
We provide not only valves, but also future-oriented building fluid control solutions - so that every building has a "breathing" pipeline system. Hengsen Group is cooperating with the world's top 500 companies to jointly promote the formulation of the "Building Fluid Control 3.0" standard and empower the new era of green buildings with Chinese smart manufacturing.
1. Technological evolution of fluid control systems in intelligent buildings
Modern building environmental control systems have developed from single device control to integrated intelligent networks, and electric valves as terminal execution units play a key role. FCU system electric valves are used for air conditioning terminal water circuit control. The thermostat controls the electric valve driver, and the driver motor drives the valve to open or close, thereby realizing the flow or disconnection of the medium in the pipeline, and supplying air through the fan coil, and finally realizing automatic control of the indoor temperature.
Based on 20 years of industry accumulation, Hengsen has broken through the limitations of "mechanical execution" of traditional valves and innovatively developed an intelligent FCU system electric valve system with the trinity of "perception-decision-execution". Its core components use a fully digital electric actuator and intelligent valve body collaborative architecture, and seamlessly connect to the building management system (BMS) through Modbus, BACnet and other protocols to achieve a precise closed loop of flow control.
2. Analysis of the technical architecture of Hengsen FCU system electric valve
1. Precision fluid control unit
Intelligent control: When the room temperature reaches the setting value of the thermostat, the thermostat turns off the power of the FCU electric valve and the reset spring closes or opens the valve, thereby cutting off or opening the water flow entering the fan coil. By closing and opening the valve, the room temperature is always kept at the temperature set by the temperature control.
Elastic sealing ring: Reduce friction loss during switching and increase the service life of the valve.
2. Reliability engineering system
High-quality raw materials: Hengsen FCU system electric valves widely use high-quality materials, such as stainless steel, cast brass, forged brass, etc., which have passed ROSH testing, and the valve body has excellent corrosion resistance, wear resistance and pressure resistance.
Modular design: Hengsen FCU system electric valve products mostly adopt modular design, with strong interchangeability of parts and components, which can be completed with simple disassembly and assembly, greatly reducing maintenance costs.
100% quality control: Every Hengsen FCU system electric valve product has undergone 100% product inspection before leaving the factory. (Hengsen Group has a national CNAS accredited laboratory, which has passed the authoritative certification of the China National Accreditation Service for Conformity Assessment (CNAS), and the test results are internationally recognized!)
3. From demand to scenario, Hengsen FCU system electric valves ensure comfortable space in buildings
In our lives, we spend most of our time in buildings, where we work, study, seek medical treatment, go shopping... and hundreds of FCU system valves and actuators may be installed in a large building, so that we can get a sense of comfort when we enter the building regardless of whether it is cold winter or hot summer. Hengsen FCU system electric valves are silently guarding the building, ensuring the comfort and safety of the building space; with millimeter-level control accuracy, they are writing the energy-saving legend of 10,000 square meters of buildings.
