VENTILATOR
Document Type and Number:
Japanese Patent JP2015169399
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a ventilator capable of reducing energy loss while keeping an indoor space hygienic.SOLUTION: A ventilator comprises: an air supply blower; an air exhaustion blower; a heat exchanger performing heat exchange between outdoor air supplied into an indoor space and indoor air discharged to outside of the indoor space; a controller independently, variably controlling a supply air volume of the air supply blower and an exhaust air volume of the air exhaustion blower; and an air-conditioner communication circuit acquiring information on an operation mode and a set temperature from an air conditioner. If the operation mode is a cooling mode, The controller sets the supply air volume to be greater than the exhaust air volume by a first air volume when an indoor temperature is lower than a set temperature or a temperature difference obtained by subtracting an outdoor temperature from the indoor temperature is smaller than a first threshold temperature difference, and sets the supply air volume to be greater than the exhaust air volume by a second air volume greater than the first air volume when the indoor temperature is higher than the set temperature and the temperature difference is greater than the first threshold temperature difference.
