ABSTRACT:
A refrigerant bypassing and filtering apparatus of an air conditioner is disclosed which is capable of effectively removing foreign matter such as slag produced in a refrigerant line, not only when the air conditioner is initially operated, but also during normal operation of the air conditioner. The apparatus includes at least one bypass line adapted to guide a refrigerant to bypass a main line through which the refrigerant flows between an outdoor unit and an indoor unit, a strainer arranged at the bypass line, a first valve arranged at the main line between opposite ends of the bypass line connected to the main line, and second valves arranged at the bypass line.
