<p>PROBLEM TO BE SOLVED: To provide a casing of ceiling-embedded air conditioner which curtails the number of parts and the man-hour thereof by eliminating not only a clearance between heat insulating materials of the casing but also post working. SOLUTION: In this casing 1 of ceiling-embedded air conditioning equipment which comprises a combination of a first side plate 2 having an L-shaped bent part 2 at one end thereof and a second side plate 3 mounted on a bent part 2c, a first external heat insulating material 2a is previously applied on both sides of the first side plate 2 separately except for a contact part 2e of the second side plate 3 at the bent part 2c of the first side plate 2. On the other hand, a first internal heat insulating material 2b is applied up to the tip of the first side plate 2 while a second internal heat insulating material 3b is applied separately on both sides of the second side plate 3 except for a contact part 3e of the second side plate with the first side plate. After a second external heat insulating material 3a is applied unto the tip of the second side plate 3, a contact part 3e of the second side plate 3 is mounted on the contact part 2e of the first side plate 2.</p> |
