Abstract

A method for cooling or heating a building is provided. An air flow can be created in an air duct and the air flow can be cooled or heated by an air conditioning system or furnace. The cooled or heated air flow can then pass through a heat exchanger connected to a radiant heating loop running through a floor or slab with a liquid circulating through them. When the airflow is being cooled or heated by the air conditioning system or furnace, the air flow will alter the temperature of the liquid circulating through the heat exchanger herefore the temperature of the slab. When the temperature of the slab varies from the temperature of the building, liquid that has been circulated through the radiant heating loop can be used to alter the temperature of the air flow passing through the heat exchanger.

Abstract

A radiant heating system includes an air-to-fluid heat exchanger, a radiant heating loop and a pump and conduits to circulate heating fluid between the air-to-fluid heat exchanger and the radiant fluid loop. The air-to-fluid heat exchanger is installed within a hot air duct connected to a conventional forced air furnace; preferably in a section of the hot air duct located near the forced air furnace with an expanded cross- section. In operation, the apparatus uses heated air supplied by the forced air furnace to heat the heating fluid circulating through the apparatus. Some of the heat from an air flow supplied by the forced air furnace passing through the hot air duct is transferred to heating fluid in the air-to-fluid heat exchanger, installed within the hot air duct. This heating fluid is then circulated through a radiant heating loop to heat a desired area.
