Nanchang Li Huang Limited, cooling fan, suction fan, wet curtain specialist Chen (Services: Nanchang, Jiujiang, Fuzhou, Jian, Xinyu, Yichun (Harvest, camphor, high security), Yingtan, Shangrao, Jingdezhen Pingxiang, Ganzhou) Third, the new wind systems compared with the usual way of a ventilation, window ventilation: wind airflow blind, may the bathroom and kitchen to the living room and bedroom smell, outdoor dust and blowing sand into the interior; noise pollution; in When using the air conditioning window, it will cause a lot of waste of energy; if no outdoor air ventilation is not possible or when it rains. 2, fan: the rainy season could not open the window, indoor easy to mold, unable to continue to exclude odors, turn-on, not a continuous ventilation. Local exhaust ventilation can only solve part of the region; in the absence of new air into exhaust poorly. 3, negative ion generator or an air purifier: only the original indoor air treatment, as the stain level of indoor air is increased, the processing ability. Unable to provide oxygen-rich fresh air; only indoor air floating processing; air purifier can absorb part of the dust and other harmful substances, but can not adsorbed gas harmful molecules. First, the new air system: air system, also known as ventilation systems in recent years, increasingly demanding ventilation premises early, several exhaust fan installed on the line, and now has failed to meet the conditions of renovation, or have become obsolete, a ventilation KTV bad is hard to stay in the customers. (Scope: KTV, coffee shop, cafe, bar, restaurant, restaurants, hotels, movie theaters, basements, Yuzu, pot shops, restaurants, beauty salons, offices, supermarkets, shopping malls, rooms, factories, villas, residential) Second, Hydropower Engineering: enterprises, factories and hydropower engineering and installation (supply distribution cabinets, cable laying, pipe installation); storefront, villas, residential water and electricity installation. Third, the electrical and mechanical equipment installation: this business is generally done in a number of environmental companies downstream of sewage and wastewater treatment equipment installation. Fourth, the villa interior ecological environment: this business is dedicated to the development of the owners live in the villa, along with the increasingly serious problem of the Earth's resources and environment, human survival environment faces a great threat, humans began to re-recognize the relationship between man and nature more concerned about their own way of life. Development of eco-construction, protect the ecological environment, has become the hot topic discussed by the late architect. Currently, the world's architects are painstaking research, explore ecological architecture development. Faced with the era of sustainable development, rapidly improve indoor environmental quality and people's lives are closely related, it is an important content. How to make the indoor environment to explore a design ecology to ecosystem practicable, interior designers imperative.
