Abstract
The invention is a system of heat distribution in buildings. It uses in-floor ducting above a concrete slab and below a raised floor to circulate air and regulate room temperature.
In the upper walls or ceilings of the rooms, air is drawn into at least one duct by a blower. The blower forces the air through a central channel that is located on the top surface of a concrete slab, either recessed into the top of a concrete slab or utilizing the top of the concrete slab as its lower surface. The air follows the channel and then flows into air tunnels (plenums) that are substantially perpendicular to the concrete channel, and run above the concrete slab and below the raised floor. As the air passes through the plenums, the concrete thermal mass is either cooled or warmed, depending on the relative temperature of the air and of the concrete slab. Near the outer walls of the building, registers in the raised floor circulate the air back into the room(s).

Description
SUMMARY OF THE INVENTION
Concrete is an excellent thermal mass and can store or release significant heat energy.
As part of this invention, a large concrete slab is used as a thermal mass, to moderate.
the air temperature inside a building. This can be especially beneficial during fall, winter and spring months, where some heating may be required in the building to maintain comfort, but where there is significant solar radiation. On cold, sunny winter days, solar-exposed windows can trap solar energy and increase the air temperature in the building. The warm air rises and is drawn by a blower into ducts located in the upper walls or ceiling of the building. The blower moves the air to a channel located on the top surface of the concrete slab, below the raised floor, and then the air is moved through the space above the concrete slab and below the raised floor. During the sunny portion of the day, when the temperature of the air is hotter than the temperature of the concrete below, the surplus heat in the air heats the concrete slab. In the evening, the air temperature in the room becomes lower than the temperature in the concrete. During this time, the blower moves the cooler air through the ducting, and the heat that was stored in the concrete is released back into the air and circulated back up into the building. This process can moderate the inside temperature of the building by minimizing wild temperature fluctuations throughout the day and night.
In a well designed house, summer sun is prevented from entering the house with the proper roof overhangs and other shading means. However, the air can still be conditioned when it is passed between the concrete slab and the raised floor.
During the daytime, heat can be removed from the air in the building and stored in a concrete slab. During the night, heat can be removed from the concrete slab into the air, as the warmed air is circulated into the room and out the windows of the house.
Continuous air movement created and sustained by the blower provides constant air movement under the floor to inhibit growth of mold and or bacteria.
An added benefit is that occupants of the building are able to walk on a comfortable, cushioned raised floor rather than directly on a concrete floor.

DETAILED DESCRIPTION OF THE INVENTION
Air circulation in the rooms of the house is partially achieved by natural convection where warm air rises and cold air falls. During the sunny part of the day, as solar energy heats the room(s) through sun-facing windows, the air temperature in the room(s) increases. This hot air naturally rises. Air is drawn through registers (12) located in the upper walls or ceiling of the building by a blower (10). The blower (10) delivers air through at least one duct (13) to an air channel (3), typically running the length of the building, on top of, or inset into the top of the concrete slab (2). This air channel (3) is the main air supply duct for the invention. In colder climates, rigid insulation (1) is typically placed under the concrete slab (2) to prevent heat loss from the lower side of the concrete slab (2). In most cases the blower (10) runs continuously to move the air across the concrete thermal mass (2) and during the sunny part of the day, the warm air from the room heats the concrete slab (2).
Spacers or "sleepers" (4) are placed in parallel on the concrete slab (2), substantially perpendicular to the air channel (3). These sleepers are spaced close enough together to provide adequate support for the raised floor (7), yet far enough apart, and with enough height, to provide good airflow inside the air plenums (5). The air plenums (5) are the voids formed by the sleepers (4), concrete slab (2) and raised floor (7). The sleepers terminate a short distance away from the outer walls of the building to allow airflow (6) to the registers (8) in the raised floor (7). "Rim" sleepers (9) are located inside the outside walls to provide support for the outer perimeter of the raised floor (7). The raised floor (7) is secured to the tops of the sleepers (4) and rim sleepers (9).
Air movement between the sleepers (9) is controlled by the adjusting the registers (8).
By properly adjusting the registers, uniform air flow can be achieved across the entire concrete slab (2). This will maximize the use of the concrete slab (2) as a thermal mass to regulate the inside air temperature in the building, and store or release the heat from the air.
Air circulation in the rooms of the house is partially achieved by natural convection where warm air rises and cold air falls. During the sunny part of the day, as solar energy heats the room(s) through sun-facing windows, the air temperature in the room(s) increases. This hot air naturally rises. Air is drawn through registers (12) located in the upper walls or ceiling of the building by a blower (10). The blower (10) delivers air through at least one duct (13) to an air channel (3), typically running the length of the building, on top of, or inset into the top of the concrete slab (2). This air channel (3) is the main air supply duct for the invention. In colder climates, rigid insulation (1) is typically placed under the concrete slab (2) to prevent heat loss from the lower side of the concrete slab (2). In most cases the blower (10) runs continuously to move the air across the concrete thermal mass (2) and during the sunny part of the day, the warm air from the room heats the concrete slab (2).
Spacers or "sleepers" (4) are placed in parallel on the concrete slab (2), substantially perpendicular to the air channel (3). These sleepers are spaced close enough together to provide adequate support for the raised floor (7), yet far enough apart, and with enough height, to provide good airflow inside the air plenums (5). The air plenums (5) are the voids formed by the sleepers (4), concrete slab (2) and raised floor (7). The sleepers terminate a short distance away from the outer walls of the building to allow airflow (6) to the registers (8) in the raised floor (7). "Rim" sleepers (9) are located inside the outside walls to provide support for the outer perimeter of the raised floor (7). The raised floor (7) is secured to the tops of the sleepers (4) and rim sleepers (9).
Air movement between the sleepers (9) is controlled by the adjusting the registers (8).
By properly adjusting the registers, uniform air flow can be achieved across the entire concrete slab (2). This will maximize the use of the concrete slab (2) as a thermal mass to regulate the inside air temperature in the building, and store or release the heat from the air.
During the night time, the air temperature in the room decreases. This cooler air is drawn through registers (12) located in the upper walls or ceiling of the building by a blower (10). The blower (10) delivers air through a duct (13) to an air channel (3), typically running the length of the building, on top of, or inset into the top of the concrete slab (2). In most cases the blower (10) runs continuously to move the air across the concrete thermal mass (2), and during the night time, the cool air from the room is heated by the concrete slab (2). Air movement between the sleepers (9) is controlled by adjusting the registers (8). By properly adjusting the registers, uniform air flow can be achieved across the entire concrete slab (2) and the registers (8) allow this warmed air to be returned to the room(s). This will maximize the use of the concrete slab as a thermal mass to regulate the inside air temperature in the building.
If it is desired to further condition the air, the air temperature can be sensed and the blower started and stopped as desired. In addition, a fumace, heat-exchanger, air-conditioner, etc. commonly used in the Heating, Ventilation, and Air Conditioning (HVAC) industry can be added to the blower.
Typically, the sleepers (4) and raised floor (7) are constructed with wood. If local building codes do not permit the use of combustible materials (such as wood) to construct air ducts, the same effect could be created by substituting metal sleepers for wood sleepers, and adding a layer of sheet metal under the raised floor, above metal sleepers. Another option would be use corrugated metal decking instead of sleepers.
The concrete slab (2) may be part of a Frost Protected Shallow Foundation (11) system, where the concrete slab is properly designed and insulated and the building does not require piles and grade beams for support in areas where the ground freezes in the winter.
The figures show the raised floor heating and cooling system utilized on the main floor of a building, where an added benefit is that it provides easy wheelchair access to the main floor. However, the system could also be used on upper concrete floors as well.
