Abstract
An air conditioner having a service valve assembly which comprises a connection body connected with a refrigerant pipe through which a refrigerant flows, and having a penetration passage through which the refrigerant flows; an opening/closing unit disposed in the connection body, and having a blocking hole for opening/closing the passage of the refrigerant flowing through the penetration passage; a plurality of ports disposed at the connection body, respectively, by a particular interval therebetween, connected with the penetration passage, and having an opened end portion, respectively; and a filter unit removably coupled to each end portion of the ports such that the refrigerant flowing through the penetration passage is bypassed to the ports to thus be filtered thereby, whereby it is possible to basically solve the problem in a blocking caused by moisture and foreign materials within a circulation system of the air conditioner, and to simplify the construction of the system by being provided with a filter and a drier which are removable.
