The invention discloses an 
air conditioning system with an air purifying function. A cooling and heating 
air conditioning device and an air purifying and dehumidifying device are arranged in an air conditioner housing, the cooling and heating 
air conditioning device comprises a closed cooling and 
heating oil tank, the exterior of the cooling and 
heating oil tank is matched with a plurality of 
semiconductor cooling and heating chips transferring heat with the cooling and 
heating oil tank, the cooling and heating 
oil tank is connected with one end of an oil outlet 
pipe through a high-temperature resistant 
oil pump, the other end of the oil outlet 
pipe is connected with an air-conditioner energy dissipater, the air-conditioner energy dissipater is connected with one end of an oil return 
pipe, and the other end of the oil return pipe is connected with the cooling and heating 
oil tank through hollow heat radiators of the 
semiconductor chips; the air purifying and dehumidifying device comprises a condensate 
water collection tank provided with a 
water collection pipe and a water feed pipe, the 
water collection pipe is connected with the lower portion of the air-conditioner heat dissipater and collects condensate water, the water feed pipe is connected with the upper portion of a 
water filter screen and inputs water to the same to form a 
water curtain, and the bottom of the 
water filter screen is connected with the condensate water collection tank through a water return pipe. The air conditioning 
system has the advantages of 
energy conservation, environment friendliness and 
air purification and dehumidification functions.
