Claims

[Scope of Claim for Utility Model Registration] (1) A heat exchange unit equipped with a total heat exchanger and a blower fan, and heat exchange in one of the total heat exchangers for guiding internal air near the ceiling in a store to the heat exchange unit. an inside air suction passage that ventilates the outside air to the heat exchange unit; an outside air intake passage that guides outside air to the heat exchange unit and ventilates it to the other heat exchange passage of the total heat exchanger; and one heat exchange passage of the total heat exchanger. an inside air blowout path that ventilates the inside air that has passed through to the outdoors; and an outside air blowout path that blows the outside air that has passed through the other heat exchange path of the total heat exchanger to near the floor in front of the open show case installed in the store. A heat exchange system for stores consisting of . (2) The store heat exchange system according to claim (1), wherein the inside air suction passage communicates with an attic air suction passage that sucks air from the attic.
