(54) Silencer for air conditioner


(57) In a refrigeration cycle including an indoor unit heat exchanger, an outdoor unit heat exchanger, and a throttling device (24,34,44,54), a silencer (21,31,41,51) having a filter (22,32,42,52) formed by compressing a single metal wire or un-cut strand wire inside is disposed. The silencer (21,31,41,51) suppresses noise released from the throttling device (24,34,44,54). The silencer (21,31,41,51) prevents adverse effects of dust generated in the refrigeration cycle on the refrigeration cycle.
