Cassette type air conditioner for mounting in the ceiling

摘要

A ceiling cassette type air conditioner includes a housing adapted for attachment to a room ceiling panel, a bell-mouth provided in the housing and having a bottom opening and an outer circumferential surface. An electrical part box is provided in the housing to accommodate electrical components. The electrical part box is arranged near that side of the bell-mouth at which secondary air flows. The electrical parts are mounted on a control board provided in the electrical part box. The electrical parts are arranged so that those which are located near the outer circumferential surface of the bell-mouth are less tall than the others.
