PURPOSE:To use a single type blower and heat exchanger, by installing a single cross flow fan and heat exchanger in such a manner that they may penetrate a partition plate for a ventilation circuit on both the inside and the outside of a room, the providing an indoor suction port and an outdoor blowout port in the lower part and the upper part in front of an indoor heat exchanger, and an outdoor suction port and outdoor blowout port on the side and the rear of a main body. CONSTITUTION:A main body is divided by a partition plate into an indoor ventilation circuit and an outdoor circuit. A single type cross fan 23 and a single type heat exchanger 22 are installed on a diagonal line to the main body in such a fashion that they may penetrate the partition plate. An air suction port 29 is installed in the front lower part of the indoor ventilation circuit while a blowout port 30 is installed in the front upper part of the circuit. A fan 23 drives an indoor air to flow as indicated by the arrow C. An outdoor suction port 32 is installed to the side of the main body in the outdoor ventilation circuit while an outdoor blowout port 33 is installed in the rear. An outdoor air is discharged in the direction as indicated by the arrow D, passing through the heat exchanger 22. Therefore, the single type fan and the single type heat exchanger can be effectively used. |
