Abstract
A heat exchange ventilator includes: a partition wall that has a bypass opening allowing an exhaust air duct upstream of a total heat exchanger to communicate with the exhaust air duct between the total heat exchanger and a humidifier, and separates the exhaust air duct upstream of the total heat exchanger and a supply air duct downstream of the total heat exchanger; a bypass damper that opens and closes the bypass opening; and a controller that performs control to open the bypass opening by the bypass damper at a first time, and close the bypass opening by the bypass damper at a second time.
Claims6
A heat exchange ventilator comprising:
- a body in which an exhaust air duct for exhausting air in a room to the outside of the room and a supply air duct for supplying air outside the room into the room are formed independently;
- a supply blower provided in the supply air duct;
- an exhaust blower provided in the exhaust air duct;
- a heat exchanger provided in the body to allow heat exchange between air flowing through the supply air duct and air flowing through the exhaust air duct;
- a humidifier disposed downstream of the heat exchanger in the supply air duct;
- a partition wall including a bypass opening that allows the exhaust air duct upstream of the heat exchanger to communicate with the supply air duct between the heat exchanger and the humidifier, and separating the exhaust air duct upstream of the heat exchanger and the supply air duct downstream of the heat exchanger;
- an opening/closing part to open and close the bypass opening;
- and
- a controller to perform control to open the bypass opening by the opening/closing part at a first time set in advance, and close the bypass opening by the opening/closing part at a second time set in advance.
