VENTILATOR

摘要

A ventilator is provided to equalize distribution of air introduced into a heat exchanger through a guide member installed on suction passages to improve the heat exchange efficiency of the heat exchanger. A case(10) has suction ports(11,13) for sucking in air. A heat exchanger(40) is installed in the case to exchange heat between indoor air and outdoor air with indoor air and outdoor air crossing each other. Guide members(60) are installed at suction passages formed between the suction ports and the heat exchanger to disperse a flow of air introduced into the heat exchanger. The guide member includes a passage reducing part(61) to reduce cross section of the suction passages, wherein the passage reducing part is formed in a shape of a square with a right side open.
