1. A clean air conditioning system using a compressor and a turbine, comprising:
an exhaust chamber exhausting polluted air in a hospital room;
an ultraviolet lamp provided in the exhaust chamber and sterilizing the air coming out of the hospital room;
a filter provided in the exhaust chamber and filtering the air passing through the ultraviolet lamp;
a compressor compressing and discharging the air passing through the filter;
a sterilization chamber connected to the compressor to form a space in which the air discharged from the compressor is sterilized while passing therethrough;
a driving turbine driven by the air discharged from the sterilization chamber to generate power and providing the generated power to the compressor; and
a heat recovery flow passage formed to circulate the air discharged from the compressor to the exhaust chamber through the sterilization chamber and to be connected from the exhaust chamber to the driving turbine.
