EXHAUST HEAT REDUCTOR IN GREENHOUSE

摘要

PURPOSE: An exhaust heat reductor in a greenhouse is provided to withdraw waste-heat generated from waste gas of a heater in the greenhouse by heat exchange for improving the efficiency of the heat exchange and reducing energy consumption. CONSTITUTION: An exhaust heat reductor in a greenhouse comprises: an exhausting duct(110) to exhaust waste gas exhausted from a heater in the greenhouse toward the outside; an inhaling duct(210) connected to a part of the exhausting duct(110) for inhaling air from the outside; a plurality of heating pipes(300) for transferring the heat of the exhausting duct(110) to the inhaling duct(210); and a blocking plate(150) forming a ventilating hole(152) to penetrate and couple the central outer circumference of each heating pipe(300) for blocking the area connected to the exhausting duct(110) and the inhaling duct(210).
