Ultra-quiet central air Fundamentals ultra-quiet central air system consists of a host of new wind ultra-quiet, air inlet, return air, ductwork, controls, new wind components. In the fresh air between the host into the building room, balcony, ceiling, equipment, ventilation when working with dust and harmful gases ventilation return air duct central new fan, the indoor air dirty harmful outside. Fresh air is filtered by the uninterruptible into the living room, bedroom, study, and other places, so that the air in a confined space to be fully replaced, nicknamed "Housing respiratory system" air system - fresh air ventilation system and other comparison A window: open windows can cause turbulence that may smell of the bathroom and kitchen into the living room and bedroom; toilet shaft may have a smell, "intrusion" phenomenon; outdoor air entrainment of a large number of outdoor dust affect indoor clean; there can not avoid annoying noise; heating will cause a lot of wasted energy waste mute unidirectional flow of new turbine prices, 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 of indoor air system price, 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; polluted air can not be quickly discharged, it will cause pollution; no ventilation path, poor air distribution; no new exhaust fan, so the new wind has been fed into the pressurized area difficult; 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. Central new fans, new fans, new air system provided by wucheng Dingrui Air Conditioning Equipment Co., Ltd. Wucheng Dingrui Air Conditioning Equipment Co., Ltd. (www.wcdrkt.com) (www.wcdrkt.com) strong, credible, Shandong Texas fan, ventilation equipment industry has accumulated a large number of loyal customers.
