HEAT EXCHANGE SYSTEM

摘要

A heat exchange system and method for heating outside air provided to a structure are disclosed. The system uses and recovers heat from waste produc ts that are being exhausted from the structure. A heated products source generates heated waste products as a result of combustion. An exhaust duct passes the heated waste products through a heat exchanger before exhaustion from the structure. An intake duct that supplies fresh outside air to the structure also passes through th e heat exchanger. The heat exchanger couples the exhaust duct and the intake duct a nd transfers otherwise unused heat from the waste products to the outside air t o increase the overall efficiency of the heated product source.
