System for heating and cooling a room with insulating layer
In a first aspect, a system for heating, cooling, or both heating and cooling a room is disclosed. The system includes a panel with a first, second, and third wall. The second wall is disposed between the first and third walls and separated by a plurality of partitions. The partitions create a first and second row of elongated channels. Each channel in the first row is bounded on two sides by two partitions and on two other sides by the first and second walls. Each channel in the second row is bounded on two sides by two partitions and on two other sides by the second and third walls. The first row of channels is a fluid layer configured to allow heated or cooled fluid to pass through. The fluid layer is in thermal communication with the room. The second row of channels is an insulating vacuum layer, with a reduced pressure that is at least 20% less than atmospheric pressure.
1. A system for heating, cooling, or both heating and cooling a room comprising:
a panel comprising:
a first wall,
a second wall, and
a third wall,
wherein the second wall is disposed between the first wall and third wall and the second wall is separated by a plurality of partitions from the first wall and from the third wall,
wherein the partitions create a first and second row of elongated channels, wherein each channel in the first row is bounded on two sides by two of the plurality of partitions and on two other sides by the first and second walls, and
wherein each channel in the second row is bounded on two sides by two of the plurality of partitions and on two other sides by the second and third walls;
wherein the first row of channels is a fluid layer configured to allow heated or cooled fluid to pass through in a serpentine fashion, the fluid layer being in thermal communication with the room; and
wherein the second row of channels is an insulating vacuum layer, with a reduced pressure that is at least 20% less than atmospheric pressure.
2. The system of claim 1 further comprising
a first end cap disposed on one end of the first row of channels and configured to prevent fluid from escaping the panel except through an inlet or an outlet; and
a second end cap disposed on an other end of the first row of channels and configured to prevent fluid from escaping the panel except through the inlet or the outlet.
3. The system of claim 2 further comprising a gap in one or more partitions, wherein the gap allows fluid to pass from one chamber into an adjacent chamber.
4. The system of claim 2 wherein the first and second end caps are configured to direct fluid from one channel to another.
5. The system of claim 2 wherein the first and second end caps close the channels in the insulative vacuum layer and are configured to maintain the reduced pressure.
6. The system of claim 5 , wherein the first end cap comprises a port with a check valve, whereby air can be pulled out of the insulating vacuum layer to create, maintain or increase the reduced pressure.
7. The system of claim 1 wherein the reduced pressure is less than 10% of atmospheric pressure.
8. The system of claim 1 wherein the reduced pressure is less than 5% of atmospheric pressure.
9. The system of claim 1 wherein the insulating vacuum layer is disposed between a wall of the room and the fluid layer.
10. The system of claim 1 wherein the fluid layer is disposed between a wall of the room and the insulating vacuum layer.
11. The system of claim 1 wherein the insulating vacuum layer is a first insulating vacuum layer and further comprising a fourth wall adjacent to the third wall and separated by partitions to create a third row of elongated channels wherein the third row of channels is a second insulating vacuum layer adjacent the first insulating vacuum layer and with a second reduced pressure that is at least 20% less than atmospheric pressure.
12. The system of claim 1 wherein the insulating vacuum layer is a first insulating vacuum layer and further comprising a fourth wall adjacent to the first wall and separated by partitions to create a third row of elongated channels wherein the third row of channels is a second insulating vacuum layer adjacent the fluid layer and with a second reduced pressure that is at least 20% less than atmospheric pressure.
13. The system of claim 1 wherein the panel is made from extruded plastic.
14. The system of claim 1 wherein the panel is made from aluminum.
15. The system of claim 1 further comprising a coating on at least one wall; wherein the coating comprises a coating with an emissivity greater than 0.97.
