Studies About Air Duct Cleaning In Air-Conditioning Systems

For contaminants of the ventilation systems in air-conditioning systems in our country, this paper study and analyzes the condition of contaminations, cause of this phenomenon and some ways to control through investigations. Introduces conception , means , technologies , devices and developments of air duct cleaning in overseas and domestic markets briefly, and find some faults in air duct cleaning industry of our country and put forward some strategies to it. This paper emphasis on the designs for access opening and the relationship between configuration of filter and dust deposition, provides some databases to designs and conducts in HVAC systems. meanwhile, the ventilation systems with different filters have been evaluated economically in this paper to prove the feasibility of standpoints that has been proposed, and predicts the trends of this industry in china at last.
