Document Type and Number:
Japanese Patent JP6448496
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a ventilation device capable of maintaining the indoor environment by making the stop/start timing of an air-supply blower appropriate.SOLUTION: A ventilation device of this invention comprises: a body having an air-supply channel and an exhaust air channel formed therein; a heat exchanger for performing heat exchange between an air-supply current and an exhaust air current; an air-supply blower provided in the air-supply channel; an exhaust fan provided in the exhaust air channel; a temperature detection part for detecting an ambient temperature; a revolution speed detection part for detecting the revolution speed of the exhaust fan; a storage part having a first revolution speed stored therein; and a control part for controlling the stop/start of the air-supply blower. The control part stops the air-supply blower when the ambient air is equal to a prescribed first preset temperature or lower, and the revolution speed of the exhaust fan is equal to the sum of the first revolution speed and a prescribed second revolution speed or more.SELECTED DRAWING: Figure 5
