Document Type and Number:
Japanese Patent JP2015068544
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat exchange ventilator which can perform an air supply operation even in an extremely cold district, which suppresses dew condensation and freezing of a heat exchanger and the like of a product, and which suppresses performance deterioration of the heat exchanger.SOLUTION: A heat exchange ventilator includes: an air supply air passage 17 communicating with an air supply outlet 6 from an air supply suction port 7 via a heat exchanger 4; an exhaust air passage 18 communicating with an exhaust blowout port 5 from the exhaust suction port 8 via the heat exchanger 4; a blower 3 for air supply provided in the air supply air passage 17; a blower 2 for air exhaust provided in the exhaust air passage 18; a control device 14 for controlling the blower 3 for air supply and the blower 2 for air exhaust; and outside air temperature detection means provided in the air supply air passage 17 and detecting the outside temperature. The control device 14 includes intermittent operation control means which performs an intermittent operation in which an operation and stop of the blower 3 for air supply are repeated for first predetermined time, according to the outside temperature detected by the outside temperature detection means and a preset temperature which is set in advance, and then, which only operates the blower 2 for air exhaust for third predetermined time while stopping the operation of the blower 3 for air supply for second predetermined time.
