Multi-online environmental technology group is a high-tech enterprise under Zoje Group. Based on the experience of clean room engineering design, production, installation and system integration accumulated by the Group for more than 20 years, the Multi-Online Fresh Air System Technology Group has conducted all-round technical cooperation with well-known scientific research institutions and universities such as Chinese Academy of Sciences, Tsinghua University and China Academy of Architecture. A number of patented technologies for air purification under different environmental and field conditions have been developed. All products of the company have passed the inspection of national quality supervision and inspection institutions, reaching the international leading level in the field of air purification. Through the testing and certification of the National Air Conditioning Equipment Quality Inspection Center, SINOCLEAN condensation technology SINOCLEAN self-cleaning technology has made a breakthrough in the research and development of similar products in the world and has been widely used at present.
1, one-way fresh air system
One-way flow system is a diversified ventilation system based on the three principles of mechanical ventilation system, which consists of fan, air inlet, air outlet and various pipes and joints. The fan installed in the ceiling is connected with a series of air outlets through pipes, and the fan is started, so that the indoor turbid air is discharged outside through the air inlet installed in the room, and several effective negative pressure areas are formed in the room. Indoor air continuously flows to the negative pressure area and is discharged outside, and outdoor fresh air is continuously replenished to the room through the air inlet installed above the window frame (between the window frame and the wall), breathing high-quality fresh air at all times. The air supply system of fresh air system does not need the connection of air supply pipes, and the air exhaust pipes are generally installed in places with suspended ceilings such as corridors and bathrooms, which basically do not occupy additional space.
2. Two-way fresh air system
Two-way fresh air system is a central mechanical air supply and exhaust system based on the three principles of mechanical ventilation system, which is an effective supplement to one-way fresh air system. In the design of two-way flow system, the positions of the exhaust main engine and the indoor exhaust outlet are basically consistent with the distribution of one-way flow, but the difference is that the fresh air in the two-way flow system is sent out by the fresh air main engine. The fresh air main machine is connected with the indoor air distributor through the pipeline, and the fresh air main machine continuously sends outdoor fresh air into the room through the pipeline to meet the fresh and high-quality air needed by people in daily life. Both the air outlet and the fresh air outlet are equipped with air volume control valves, and indoor ventilation is realized through the power discharge and transportation of the main engine.
3. Ground air supply system
Because carbon dioxide is heavier than air, the closer it is to the ground, the lower the oxygen content. From the point of view of energy saving, installing fresh air system on the ground will get better ventilation effect. The cold air sent from the air outlet at the bottom of the floor or the wall or the air outlet at the upper part spreads on the surface of the floor to form an organized air flow organization; A buoyancy wake is formed around the heat source to take away the heat. Because of the low wind speed, the airflow organization is turbulent and smooth, and there is no large vortex, the air temperature in the indoor working area is relatively consistent in the horizontal direction, but it is more obvious and higher when layered in the vertical direction. The upward wake generated by the heat source can not only take away the heat load, but also bring the dirty air in the work area to the upper part of the room and exhaust it from the exhaust port at the top. The fresh air, waste heat and pollutants in the bottom tuyere move upward driven by buoyancy and airflow organization, so the ground air supply fresh air system can provide good air quality for indoor working areas.
The fresh air system uses special equipment to send fresh air into the room on one side of a closed room, and then uses special equipment to exhaust it outside on the other side. Will it form indoors? Fresh air flow field? So as to meet the needs of indoor fresh air ventilation. The implementation scheme is as follows: a fan with high wind pressure and large flow rate is used to blow air into the room from one side by mechanical force, and the air is discharged to the outside from the other side by a specially designed exhaust fan, so that a fresh air flow field is forcibly formed in the system. At the same time of air supply, indoor air is filtered, disinfected, sterilized, oxygenated and preheated (in winter).
Multi-connected fresh air system is a brand of fresh air system which is widely used at present. The above article mainly introduces some classifications and advantages of multi-connected fresh air system. It is not difficult to see that the multi-online fresh air system can bring a lot of convenience to people's lives, and everyone can choose with confidence when purchasing.
