Experimental study on performance of multifunctional household outdoor air purification units

In view of the present atmosphere pollution situation, develops a multifunctional household outdoor air purification unit to supply comfortable and healthy air to the indoor environment. In order to supply satisfactory outdoor air to the indoor environment in different seasons, puts forward three operational control modes and a scheme of outdoor air purification. Tests the heat-moisture performance of the unit in a standard enthalpy difference laboratory and the purification performance near the viaduct. The results show that the unit is reliable and energy efficient, and possesses excellent heat-moisture and purification performance in different working conditions.
