WIPO Patent Application WO/2016/056141

Kind Code:

A1

Abstract:

A heat exchanger ventilation device comprising: a heater connection terminal that is connected to an externally connected heater (8), wherein the heater is disposed in an outside air supply duct connected to the outside of an air supply passage and heats the air supply flow that is flowing into a heat exchanger by passing through the air supply passage; a temperature sensor (6) that measures the temperature of the air supply flow passing through the air supply passage; and a control unit (22) that controls operating of an air supply blower (5) and an exhaust blower (4) as well as turning the externally connected heater (8) on and off on the basis of the measurement results of the temperature sensor (6). The air supply blower (5) can operate at a plurality of intensities for which the generated air supply flow rates are different. The control unit (22) prevents a state in which the air supply blower (5) operates at an intensity that is lower than a preset intensity while the externally connected heater (8) is on.
