The new air system - fresh air ventilation system and other comparison A window: window will cause turbulence, could smell the bathroom and kitchen into the living room and bedroom; toilet shaft may have a smell, "intrusion" phenomenon; outdoor air entrainment lot Outdoor dust, affect the indoor clean; there can not avoid annoying noise; heating will cause a lot of energy waste, waste of electricity. For these reasons, the use of the way the ventilation window, your quality of life will be greatly reduced. B fan: fan is unable to continue to exclude unpleasant odor, can not meet the replacement needs of indoor fresh air; the fragile, post-maintenance costs increase; not continuous ventilation; noisier; no new air into exhaust resistance increases large, ineffective. Even without the above shortcomings, taking into account the row of small fan air volume, limited scope, you can not have an exhaust fan installed in each room, even if the effect can not be achieved installed. Fan can only achieve local exhaust short time, no organization reasonable pressure and air flow path, and therefore can not achieve a real sense of air displacement. And the exhaust fan does not run continuously 24 hours, noisy fan. To achieve high-quality air in the true sense of displacement, the system must be professional job! Air-conditioning with a part of the new C wind: Wall conditioners accepted air from the air conditioner itself, forming a closed loop between the room and air conditioning systems; some slightly new wind central air conditioning, fresh air is a positive pressure in the room already Regional difficult to continue to air; air vents at the large population of bacteria, especially in winter, the temperature of air conditioning mouth is a breeding ground for bacteria; indoor and outdoor air can not achieve the purpose of a full exchange, and the price is higher than ordinary air. D common pipeline blast: difficult to control each outlet air flow, air can not be changed according to individual needs; rapid discharge of polluted air can not mute the fan, it will cause pollution; poor ventilation path not muted fresh air unit, air; there is no two-way flow of exhaust Quiet fan, so the new wind in the positive pressure area has become difficult fed; noisier; life is short, can not meet the requirements of continuous ventilation. With fresh air system than with the regular army of guerrillas is the difference. The new ultra-quiet fan bi-directional flow of new central air system program works full hot air system by the total heat exchange host, the new outlet, air vents, control system through a combination of unique design of the pipeline. 24 hours a day by ventilation, indoor whole to maintain fresh air circulation, the total heat exchanger ventilation, hot and cold compensation, can reduce energy loss during the silent ventilation fan system, to provide you with a full range of energy efficient ventilation environment. ⊙ ① oxygenating ---- Program features 24-hour cycle of indoor and outdoor fresh air, keep the indoor 24 hours of fresh oxygen. ---- ② remove interior decoration in addition to aldehyde contaminants, formaldehyde, benzene, VOC and other pollutants, reduce harm to human body. ③ purify ---- clean air PM2.5, keep indoor air clean and efficient 24 hours. ④ saving ---- advanced energy recovery systems total heat exchange, ensure the indoor air energy, and reduce energy losses. ⑤ intelligent ---- based on indoor air quality, intelligent monitoring and operation of two-way flow silent fan _ Dingrui air conditioning (certified) _ Silent Fan Co. wucheng Dingrui provided by air-conditioning equipment.
