The invention provides an air purifying
system. The air purifying
system is arranged between the interior and exterior of a building and comprises an air guide
pipe, a cooling module, a fan, an air purifying module and a
wind power generator. An air inlet and an air outlet are formed in the two ends of the air guide
pipe respectively, the cooling module is arranged on the air inlet, the fan is arranged in the air guide
pipe, the air purifying module is arranged in the air guide pipe and arranged close to the air outlet relative to the fan, and the
wind power generator is electrically connected with the fan. When an air conditioner is turned on,
airflow generated by the air conditioner can drive the
wind power generator to generate
electricity to drive the fan to work. Compared with the prior art, the air purifying
system uses a tubular filtering device and is arranged in a wall, and the power of the air purifying system comes from the small
wind power generator; in addition, the air purifying system can recover the refrigerating capacity of condensate water of an indoor unit of the air conditioner, cool outdoor air and then send the outdoor air into a room, it is avoided that as the outdoor air is high in temperature, the
indoor air-conditioning effect declines, and the purposes of
environmental protection and
energy conservation are achieved.
