What is a new fan?
The new fan is an effective air purification equipment, which can circulate indoor air. On the one hand, the dirty indoor air is discharged outside, on the other hand, the fresh outdoor air is input indoors through sterilization, disinfection, filtration and other measures, so as to keep the room fresh and clean at all times. The new fan adopts the patented technology of fresh air convection, which makes indoor air convection and replaces indoor air to the maximum extent through independent air supply and air introduction. The new fan has built-in multifunctional purification device. The new fan is mainly divided into two types: exhaust fan and blower fan, which can be installed in most indoor environments with convenient installation and comfortable use. The new fan is a healthy companion of home life.
Advantages of the new fan:
1. Using specially designed special high-pressure head and large-flow fan, mechanical ventilation is realized, indoor air quality is improved by purely physical means, and there is no secondary pollution and derivative pollution.
2. The air flow and velocity meet the requirements of the new standard of healthy residence, and there is no side effect and discomfort to human body. Integrated multiple functions (i.e. dust removal, sterilization, oxygenation and heating). Because there is no pipeline connection, it can effectively prevent cross-infection of germs in indoor polluted air through pipelines.
3. The unique dynamic-static balance technology is applied to make the noise of mechanical operation ≤45dB, and various functions such as disinfection, sterilization, heating, dust prevention and sound insulation can be combined into different series of products according to the climate and geographical environment of the application area.
4. Because the pipeline is not used, the workload of pipeline installation and maintenance is saved, the system cost is low, energy saving and environmental protection are realized, and the shortcomings of high cost, complicated installation and difficult cleaning and maintenance of large-scale pipeline fresh air system are effectively solved.
5. Small and beautiful, reasonable structure. According to different occasions, we can provide wall-mounted, ceiling-mounted, cabinet-mounted and other models. Convenient installation and maintenance, fresh and soft air, and can be widely used in homes, offices and public places.
Selection of new fan:
1. Select the form of the new fan according to the installation settings;
2. The air volume and wind pressure of equipment shall be selected on the principle of not less than the design value; ? Determine the appropriate fresh air volume according to the purpose, area, number of internal staff and the fresh air volume required by each person? Q(m*m*m/h)？ General ward: 17-42? Sports: 8-20? Cinema and department store: 8.5-2 1? Office: 25-62? Computer room: 40- 100? Restaurant: 20-50? Superior room: 30-75? Meeting room: 50- 125? How many times have fresh air been changed in the room? P (times/hour)? General ward: 1.06-2.65? Sports: 0.5- 1.25? Cinema and department store: 1.06-2.66? Office: 1.56-3.9? Computer room: 2.5-6.25? Restaurant: 1.25-3. 13? Superior room: 1.88-4.69? Meeting room: 3. 13-7.85438+0
Remarks: (1)? When determining the amount of fresh air required for a room, it should be considered comprehensively according to the size of the room space and the number of indoor personnel. According to the recommended data in the above table, the fresh air quantity is calculated according to the "fresh air quantity required by each person" and "indoor air exchange times", and the larger value is taken as the basis for equipment selection. ? (2) For special industries, such as hospitals (operating rooms, intensive care units), laboratories, industrial workshops, etc., the required fresh air volume should be determined according to the relevant provisions of the document industry.
3. Determine the design conditions of cooling capacity and heating capacity;
4. In principle, a fresh air unit is only responsible for the fresh air required for the first floor;
Precautions for installation of new fan:
A, the foundation of the new fan shall be smooth and firm, and the foundation height shall be ≥200mm or higher.
B, is it? The diameter of the air outlet of the new fan can only be increased, but not decreased. Finally, an insect-proof net should be installed at the exit, and a rain cap should be added when the exit is on the upper side.
C the steel bracket of the new fan must be fixed on the concrete foundation, and a rubber damping pad must be added between the steel bracket and the foundation of the new fan. All the fans and motor parts are installed on the integral steel bracket, and the steel floor frame is installed on the damping pad at the top of the foundation. The damping pad is preferably made of porous rubber plate.
D, the new fan and the air duct are connected by hoses (flexible materials, nonflammable), the length is not less than 200mm, and the pipe diameter is the same as the inlet and outlet dimensions of the fan. In order to ensure that the hose is not deformed during the operation of the system, it should be installed with moderate tightness. For the canvas hose installed at the suction end of the fan, it can be installed tighter to prevent the fan from being sucked during operation and reduce the cross-sectional size of the canvas hose.
