<p>PROBLEM TO BE SOLVED: To simplify the operation of wiping an inlet grille while avoiding lowering of an air conditioning capacity due to an increase in a pressure loss of air let in. SOLUTION: In regard to air conditioning equipment 1 of a ceiling embedded type to an air inlet 9a to which an inlet grille 12 is fitted, the central part of the inlet grille 12 is made a blocking face part 14 and this part is positioned below the inlet 9a with a prescribed space left between, while the lower side of this blocking face part 14 is made flat. The outside parts of the blocking face part 14 are made slant parts 16 which are tilted upward toward the outside so that they are directed from the outer edge part of the blocking face part 14 to the edge part of the opening of the inlet 9a. Inlet openings 17 for introducing indoor air are formed in the slant parts 16. A pressure loss of air let in is reduced by a straightening space formed between the inlet openings 11 and the air inlet 9a.</p> |
