摘要

PURPOSE: An indoor device of a duct-connected air conditioner is provided to easily couple suction and discharge ducts, to facilitate cleaning and replacing of a suction filter by disposing the suction filter at an air suction port, and to improve air purification efficiency by adding a high efficiency filter. CONSTITUTION: An indoor device(50) of a duct-connected air conditioner is composed of a cabinet(52); an upper panel(64) installed on the upper part of the cabinet and formed with air suction and discharge ports(54,56); a barrier(94) for dividing the inside of the cabinet into air suction and discharge passages; a blower unit(70) mounted in the air discharge passage; a suction filter(100) arranged at an air suction port; and a high efficiency filter(102) formed in the air suction passage. The high efficiency filter is installed at the lower end of the air suction passage under the barrier.
