<p>PROBLEM TO BE SOLVED: To provide a heat exchanger of embedment-in-ceiling type where the user can execute the maintenance of electric equipment without operating itself. SOLUTION: A heat exchanger 1 is integrated, at an interval B to the inner face on its one side, into the body casing 2 which has an opening along a ceiling face 41, and a maintenance window 71 is opened on its one side, and inside the maintenance window 17, an electric equipment mounting plate 18 which can close the maintenance window 17 from inside, with a wider area than the opening area, is arranged capably of mounting and removal. The electric equipment mounting plate 18 is provided with an electric equipment cover 19 projecting outward of the body casing 2 from the maintenance window 17, and the maximum width dimension C between the electric equipment mounting plate 18 and the electric equipment cover 19 is made smaller than the interval B.</p> |
