HEAT RECOVERY VENTILATOR FOR VENTILATOR

摘要

PURPOSE: A heat recovery ventilator for a ventilator is provided to improve heat exchange efficiency of exterior air and interior by improving the structure of air flow passages. CONSTITUTION: A heat recovery ventilator for a ventilator has unit heat exchange parts(45) disposed between heat exchange plates(45a) and composed of corrugated plates(45b) to form unidirectional flow passages for air. The unit heat exchange parts are layered to be crossed with the adjacent air flow passages. The unit heat exchange parts have supply passages(47) for exterior air and exhaust passages for interior air. The air flow passages are slant at a predetermined angle to the passing direction of air, to improve convective heat transfer efficiency through friction of the corrugated plate and the air passing through the air flow passages. Thus, heat exchange efficiency is improved.
