Abstract

A cooling/heating system used in an air conditioner comprises a silencer (30) comprising at least one body (31) coupled in series to a refrigerant pipe which is coupled to an expansion device (21) of an indoor unit (20), and a spatial comparting member (32) provided in such a way that an inner space of the body (31) is comparted across a flowing direction of a refrigerant, the spatial comparting member (32) being perforated with a refrigerant passing hole (32c), through which the refrigerant flows. The silencer (30) further comprises a screen (33) formed of a mesh type, and positioned in an inside of the body (31) such that the refrigerant flows through the screen (33).
