Document Type and Number:
Japanese Patent JP2617802
Kind Code:
B2
Abstract:
PURPOSE:To perform an efficient sucking of hot air near a ceiling part of a case of a control panel and to enable a heat exchanging operation to be carried out by a method wherein a corrugated fin is stored in a vertical part of an inverted L-shaped heat exchanger fixed to the case of the control panel, a surrounding air suction port and a discharging port are arranged outside the vertical part and the indoor air discharging port is arranged inside the vertical part and further the indoor air sucking port is arranged at a horizontal projecting part. CONSTITUTION:An indoor air suction port 10 is arranged at a ceiling part of a case 10 of a control panel. An indoor fan 3 is arranged at a horizontal projection 2a of its corresponding heat exchanger device 2. Hot air within the case 1 is efficiently sucked and sent to a corrugated fin 5 at a vertical part 26. The air heat exchanged and cooled is injected from an indoor air discharging port 11 of an inner wall of the case 1 into the case 1. In turn, the surrounding air sucked from the indoor air suction port 12 and a surrounding air fan 4 is sent to the corrugated fin 5 and heat exchanged with the indoor air, thereafter the air is discharged out of the surrounding air discharging port 13. Oil mist sucked together with the surrounding air and adhered to the corrugated fin 5 is flowed down along the wall surface of the vertical part and then the mist is discharge from the drain 14.
