The new air system is a set of independent air handling system from the new wind ventilators and pipe fittings composed of fresh air ventilator outdoor fresh gas through filtration, purification, after the sterilization process, piped into the room. While the indoor pollution, low oxygen air from the outdoors. The new air system is an open loop system. Indoors principle will form the "new wind flow field" to meet the needs of indoor fresh air ventilation. Central air system installed using conduit for ventilation duct negative pressure than those without or supercharged air system has obvious advantages. It can be formed in the local indoor air convection air system installation, ventilation achieve the desired effect, so installing a new ventilation system the best selection of ventilation pipes. First, it said new central air system hoses: general composite hose, plastic hoses are also used Panasonic indoor air system, such as the kind of hood is, as a relatively thin plastic hose is also easy to aging embrittlement, Indoor air system is rarely used in the top ten brand new air system, because the bad is not easy to replace. PVC composite hose on the outer layer of the protective film to make the surface, there are two aluminum and steel support pipe, the presence of steel pipes in order to prevent bending bonded together and not easily crushed. Movement of the switch group is completely silk paper material, heat collection chamber, the sensible heat exchanger is an aluminum foil movement, i.e., the indoor heat can be recovered, can be recycled indoor humidity, heat recovery efficiency can be 70% or more Indoor air system efficiency, the heat exchange efficiency of the new wind ventilators in more than 40%, heat recovery units divided into vertical and horizontal installation. ? Ability Measurement conditions: dry bulb 27 ℃, wet-bulb 19.5 ℃, water temperature 7 ℃. The temperature difference between 5 ℃? Installation, so that through a test port can perform all maintenance and repair. Linear supply and exhaust manner very easy to install. Nanjing Environmental Engineering Equipment Co., Ltd.
