Abstract
A heat exchange system and method for heating outside air provided to a structure are disclosed. The system uses and recovers heat from waste products 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 the heat exchanger. The heat exchanger couples the exhaust duct and the intake duct and transfers otherwise unused heat from the waste products to the outside air to increase the overall efficiency of the heated product source.
Claims19
A heat exchange system for heating outside air provided to a structure, comprising:
- an exhaust duct to remove heated exhaust products from the structure, wherein the heated exhaust products are generated by a heated products source;
- an intake duct to supply outside air to the structure;
- and
- a heat exchanger coupled to the heated products source through the exhaust duct and coupled to the outside air through the intake duct, wherein the exhaust duct and the intake duct pass through the heat exchanger to transfer heat from the heated exhaust products to the outside air.
A heat exchange system for heating outside air provided to a structure, comprising:
- an exhaust duct to remove heated exhaust products from the structure, wherein the heated waste products are generated by a heated products source;
- an intake duct to supply outside air to the structure;
- and
- a heat exchanger coupling the exhaust duct and the intake duct to transfer heat from the heated exhaust products to the outside air, wherein the heat exchanger is coupled to the heated products source through the intake duct and the exhaust duct and the heat exchanger is provided in a remote location from the heated products source.
A method of heating outside air supplied to a structure comprising the steps of:
- generating heated exhaust products of combustion from a heated products source;
- passing the heated exhaust products from the heated products source into an exhaust duct;
- conducting the heated exhaust products within the exhaust duct and through a heat exchanger prior to exhaustion of the heated exhaust products from the structure, wherein the heat exchanger is provided in a location remote from the heated products source;
- passing outside air into an intake duct to supply the outside air to the structure;
- conducting the outside air within the intake duct and through the heat exchanger prior to supplying the structure with the outside air;
- passing the intake duct and the exhaust duct through the heat exchanger;
- and
- coupling the intake duct and the exhaust duct within the heat exchanger to transfer heat from the heated exhaust products to the outside air.
