Abstract：
At present, our country has increasingly high requirements for energy saving and emission reduction, and the energy consumption of air conditioning system accounts for more than 30% of the total energy consumption of buildings. This paper focuses on dual-fan air treatment system with supply and return fans, which has the advantages of multiple working modes, energy saving and emission reduction, and wide application range. The research results show that the system has significant advantage in the use of outdoor air for natural cooling.
