The upper and lower parts of the frame 3a are held in a state where they can be slid back and forth, and also serve as partition walls upstream and downstream of the high-performance filter 3 for removing fine particles. 7 is the same,
A filter guide E that holds the coarse dust removal filter 10 has the same function as the filter guide H6 described above. Reference numeral 8 denotes an outdoor air outlet for discharging the treated outdoor air into the room, and this constitutes an intake path. 9 is an indoor air intake port, 10 is a coarse dust removal filter that removes dust from the indoor air, 5b is an indoor air exhaust blower that sucks indoor air and discharges it to the outside, and 11 is an indoor air outlet. The exhaust passage is constructed as described above, and the total heat exchanger unit 4 is provided between the intake passage and the exhaust passage, and exchanges heat between the outdoor air and the indoor air flowing through the intake passage and the exhaust passage. 14 is an indoor air intake grill attached to the ceiling panel 13; 15 is a duct that communicates the indoor air intake grill 14 with the indoor air intake port 9 of the air conditioner main body 1; and 16 is an outdoor air intake grill of the air conditioner main body 1. A duct connected to the air outlet 8 communicates with an outdoor air outlet grille 17 attached to the ceiling panel 13 through a branch pipe 16a. 1
8 is an outer wall, and 19 is an inspection port provided on the ceiling panel 13.

Next, to explain the operation, outside air is sucked into the air conditioner main body 1 from the outdoor air suction port 2, passes through space A, is removed by a high-performance dust removal filter 3, and passes through spaces B and C, where it is completely heated. Exchanger unit 4
flow into. On the other hand, indoor air is sucked in from the indoor air suction grille 14 and into the air conditioner main body 1 through the duct 15 and the indoor air suction port 9. Then, it passes through the room D to the coarse dust removal filter 1.
Dust is removed at 0 and flows into the total heat exchanger unit 4 through spaces E and F, where heat is exchanged between the outdoor air and indoor air, and the indoor air is passed through the indoor air exhaust blower 5.
b, the indoor air is discharged from the indoor air outlet 11 to the outside of the outer wall 18. Further, the outdoor air is discharged indoors from the outdoor air blowing grill 17 through the outdoor air outlet 8, the branch pipe 16a of the duct 16, and the outdoor air blower 5a.

[Problem that the invention attempts to solve]

Conventional air conditioners are configured as described above, so in order to effectively utilize the collection area of the filter, a space is required between the air intake port and the filter, making the air conditioner itself large. There was a problem with the shape.

The present invention was made to solve the above-mentioned problems, and its purpose is to obtain an air conditioner that is smaller than the conventional one.
