The outdoor air flow A is generated by driving the condensing fan 133. When the condensing fan 133 is driven, outdoor air can be sucked toward the inner center of the case 100 through the outdoor suction unit 102 provided in the two case side parts 101.

The outdoor air sucked into the case 100 through the one outdoor intake part 102 passes through the control box 200 and the reactor assembly 300 located adjacent to the case side part 101, 200 and the reactor assembly 300, respectively.

At this time, since the control box 200 and the reactor assembly 300 are respectively located at the upper and lower portions of the outdoor air passage 195, a part of the drawn outdoor air cools the control box 200, A portion of which may cool the reactor assembly 300. Therefore, since the cooler outdoor air cools the control box 200 and the reactor assembly 300, the cooling efficiency can be improved.

The outdoor air having passed through the control box 200 and the reactor assembly 300 is rearwardly turned and flows to the axial suction side of the condensing fan 133 to form a first outdoor side flow path.

The outdoor air passing through the condensing fan 133 flows through the axial discharge side of the condensing fan 133 and flows through the outdoor discharge unit 109 after passing through the condenser 130, The second outdoor-side flow path is formed.

[Room side air flow (B)]

The indoor air flow (B) is generated by driving the evaporation fan (160). When the evaporation fan 160 is driven, indoor air can be sucked toward the inner center of the case 100 through the plurality of indoor suction units 115 and 116.

The indoor air sucked into the evaporator 140 forms a first indoor-side flow path toward the inflow side of the evaporator 140 and flows from the outlet side of the evaporator 140 to the second indoor side Thereby forming a flow path.

The indoor air that has passed through the evaporation fan 160 is discharged in the radial direction of the evaporation fan 160 and flows into the third indoor side Thereby forming a flow path. The indoor air flowing inside the discharge guide 170 flows forward toward the front panel 110 and can be discharged to the indoor space through the discharge portion 117 of the front panel 110. [
