Title:
HEAT EXCHANGING TYPE VENTILATOR
Document Type and Number:
Japanese Patent JPH01137139
Kind Code:
A
Abstract:
PURPOSE:To make an effective utilization of a construction cost even if a circulating function is provided in addition to a heat exchanging and ventilating function by a method wherein the heat exchanging and ventilating function and the circulating function can be exchanging with each other by opening or closing a first damper and a second damper. CONSTITUTION:If a first damper 14 and a second damper 15 are closed to perform an operation, interior air is sucked from an interior suction port 2 by a discharging blower 7, flowed from an upstream side of a discharging passage of a heat exchanger 8 to the downstream side discharging port 5. In turn, the surrounding air is sucked from an outdoor suction port 4 by an air feeding blower 6, flowed from the upstream side of the air supplying passage of the heat exchanger 8 to its downstream side and then supplied from the interior discharging port 3. The discharged flow and the supplied flow described above are heat exchanged with each other at the heat exchanger 8, respectively. Then, if the first damper 14 and the second damper 15 are opened to operate the device, the interior air is sucked from the interior suction port 2 by the discharging blower 7, flowed to the downstream side of the air supplying passage of the heat exchanger 8 and then supplied from the interior discharging port 3.
