Title:
HEAT EXCHANGING VENTILATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/225224
Kind Code:
A1
Abstract:
This heat exchanging ventilation device has: an outer casing provided with a supply air flow passage through which a supply air flow flows, and also with a discharge air flow passage through which a discharge air flow flows; and a heat exchanger provided with a square prism-shaped heat exchange element and also with heat exchanger frames installed at the four corners of the heat exchange element, the heat exchanger being provided between the supply air flow passage and the discharge air flow passage and exchanging heat between the supply air flow and the discharge air flow. The heat exchanging ventilation device has a plurality of guide rails (18) which are installed within the outer casing, engage with the heat exchanger frames (22), and guide the mounting and removal of the heat exchanger into and from the outer casing. The guide rails (18) each have: an end surface facing section (18a) facing an end surface (22a) of a heat exchanger frame (22); a side surface facing section (18b) having a clearance relative to a side surface (22b) of the heat exchanger frame (22); a holding section (20) protruding from the side surface facing section (18b) toward the side on which the heat exchanger frame (22) is disposed; and a seal member (21) provided in the clearance and sealing between the heat exchanger frame (22) and the guide rail (18).
