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.
Claims22
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 enters into, passes through, and exits from 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 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 intake duct enters into, passes through, and exits from the beat exchanger to transfer heat from the heated exhaust products to the outside air.
A fireplace and heat exchange system for heating outside air provided to a structure, comprising:
- a combustion chamber enclosure defining a combustion chamber, wherein heated exhaust products are generated in the combustion chamber;
- an exhaust duct to remove the heated exhaust products generated by the fireplace from the structure;
- an intake duct to supply outside air to the structure;
- and
- a heat exchanger coupled to the fireplace through the exhaust duct and coupled to the outside air through the intake duct, wherein the exhaust duct enters into, passes through, and exits from the heat exchanger to transfer heat from the heated exhaust products to the outside air.
