PURPOSE:To improve comfortableness by forming a body in a vertical type in a simultaneous air supply/discharge type ventilator having a heat exchanger provided therein, providing an indoor side suction port at an upper end, an indoor side discharge port at a lower end, and feeding a discharge flow vertically downward without bringing the discharge flow in the chamber into contact with a human body. CONSTITUTION:An indoor side suction port 54 is provided at an upper end of an outer housing 50 made of a box, an indoor side discharge port 55 is provided at a lower end thereof, an outdoor side suction port 60 is similarly provided at an upper part of a back surface of the housing 50, and an outdoor side discharge port 61 is provided at a lower part thereof. Then, a discharge blower 68 and an air supply blower 69 for forming a discharge passage communicating with the port 54 and the port 61 and an air supply passage communicating with the port 60 and the port 55 are installed, and the passages are crossed. A heat exchanger 34 is mounted at an intersection between the discharge passage and the air supply passage. Since the atmospheric air into a chamber flows vertically down from the port 55, it is not brought into contact with a human body, and comfortable air conditioning for inhibiting the human body to feel chilled air is obtained. |
