In the current living environment, many friends have felt the disadvantages caused by environmental pollution. If they want to avoid environmental pollution, they need to purchase a more suitable fresh air system. The multi-line fresh air system is a relatively well-known product. So, what types of multi-line fresh air systems are there? The following article will introduce it to you.
Multi-line Environmental Technology Group is a high-tech enterprise under China Clean Group. Multi-line Fresh Air System Technology Group Co., Ltd. relies on the group’s more than 20 years of experience in clean room engineering design, production, installation and system integration to cooperate with China The Academy of Sciences, Tsinghua University, China Academy of Architectural Sciences and other well-known scientific research institutions and universities conduct all-round technical cooperation. It has developed a number of patented air purification technologies suitable for different environments and fields. All the company's products have passed the testing of the national quality supervision and inspection agency, and have reached the international leading level in the field of air purification. Passing the testing and certification of the National Air Conditioning Equipment Quality Inspection Center, SINOCLEAN condensation technology SINOCLEAN self-cleaning technology has made cutting-edge breakthroughs in the research and development of similar international products and has been widely used.
1. One-way flow fresh air system
The one-way flow system is a diversified combination of central mechanical exhaust and natural air intake based on the three principles of mechanical ventilation systems. The ventilation system consists of fans, air inlets, air exhaust outlets, and various pipes and joints. The fan installed in the ceiling is connected to a series of exhaust vents through pipes. When the fan is started, the indoor turbid air is discharged to the outside through the suction vent installed indoors through the fan. Several effective negative pressure zones are formed indoors, and the indoor air continues to circulate. It continuously flows to the negative pressure area and is discharged outdoors. The outdoor fresh air is continuously replenished into the room through the air inlet installed above the window frame (between the window frame and the wall), so that you can always breathe high-quality fresh air. The air supply system of this fresh air system does not require the connection of air supply ducts, and the exhaust ducts are generally installed in corridors, bathrooms and other places where there are usually suspended ceilings, basically taking up no additional space.
2. Two-way flow fresh air system
The two-way flow fresh air system is a central mechanical air supply and exhaust system based on the three major principles of mechanical ventilation systems, and is an alternative to one-way flow fresh air. An effective addition to the system. In the design of the two-way flow system, the positions of the exhaust host and the indoor air outlet are basically the same as the one-way flow distribution. The difference is that the fresh air in the two-way flow system is sent in by the fresh air host. The fresh air host is connected to the indoor air distributor through a pipe. The fresh air host continuously sends outdoor fresh air into the room through the pipe to meet the fresh and high-quality air needed in people's daily life. Both the exhaust outlet and the fresh air outlet are equipped with air volume control valves, and indoor ventilation is achieved through the power exhaust and delivery of the host machine.
3. Ground air supply system
Since carbon dioxide is heavier than air, the closer to the ground, the lower the oxygen content. From the perspective of energy saving, installing the fresh air system on the ground will result in Better ventilation. The cold air sent from the air supply vents at the bottom or top of the floor or wall spreads on the floor surface to form an organized airflow organization; and a buoyant wake is formed around the heat source to take away the heat. Because the wind speed is low, the airflow organization is turbulent and gentle, and there are no large eddies. Therefore, the air temperature in the indoor working area is relatively consistent in the horizontal direction, but stratified in the vertical direction. The higher the floor height, the more obvious this phenomenon is. The upward wake generated by the heat source not only takes away the heat load, but also brings the dirty air from the work area to the upper part of the room, where it is discharged through the exhaust vent at the top. The fresh air sent out from the bottom air outlet, waste heat and pollutants move upward under the driving force of buoyancy and air flow organization, so the ground air fresh air system can provide good air quality in the indoor work area.
The fresh air system is based on the use of special equipment on one side of a closed indoor room to send fresh air into the room, and then discharge it to the outdoors through special equipment on the other side. A "fresh air flow field" will be formed indoors to meet the indoor requirements. The need for fresh air. The implementation plan is to use high wind pressure and large flow fans, rely on mechanical force to supply air from one side to the room, and use a specially designed exhaust fan to discharge it to the outside from the other side to force the formation of a fresh air flow field in the system.
While supplying air, the air entering the room is filtered, disinfected, sterilized, oxygenated, and preheated (in winter).
Multi-connection fresh air system is a type of fresh air system brand that is currently widely used. The above article mainly introduces some classifications and advantages of multi-connection fresh air system. It is not difficult to see that the multi-connection fresh air system can bring a lot of convenience to people's lives, and everyone can choose with confidence when buying it.
