Multi-zone temperature modulation system for bed or blanket

A system for temperature-conditioning a surface comprising:

• an upper layer;
• a lower layer;
• at least two conduit circuits for directing water through at least two independent temperature zones, wherein the at least two conduit circuits are positioned between the upper layer and the lower layer;
• padding positioned between the upper layer and the at least two conduit circuits;
• a control unit to selectively heat or cool the water, wherein the control unit consists of one control unit;
• wherein the at least two conduit circuits include a first conduit circuit and a second conduit circuit;
• wherein the at least two independent temperature zones include a first independent temperature zone and a second independent temperature zone, wherein the first independent temperature zone includes the first conduit circuit and at least one first temperature sensor physically located within the first independent temperature zone operable to measure an actual temperature of the first independent temperature zone, wherein the at least one first temperature sensor is surrounded by the first conduit circuit, and wherein the second independent temperature zone includes the second conduit circuit and at least one second temperature sensor physically located within the second independent temperature zone operable to measure an actual temperature of the second independent temperature zone, wherein the at least one second temperature sensor is surrounded by the second conduit circuit;
• wherein the one control unit includes a pump for pumping the water through the at least two conduit circuits, wherein the pump consists of one pump, wherein the one pump includes a first inlet, a second inlet, a first outlet, and a second outlet, wherein the at least two conduit circuits include a first conduit circuit and a second conduit circuit, and wherein a first end of the first conduit circuit is connected to the first outlet of the one pump, a second end of the first conduit circuit is connected to the first inlet of the one pump, a first end of the second conduit circuit is connected to the second outlet of the one pump, and a second end of the second conduit circuit is connected to the second inlet of the one pump;
• wherein the one control unit includes a reservoir provided with a thermoelectric device, wherein the reservoir consists of one reservoir, and wherein the thermoelectric device consists of one thermoelectric device operable to provide heating and cooling for the one reservoir;
• wherein the at least two conduit circuits are comprised of silicone;
• wherein the at least one first temperature sensor is connected to the one control unit and provides the actual temperature of the first independent temperature zone to the one control unit;
• wherein the at least one second temperature sensor is connected to the one control unit and provides the actual temperature of the second independent temperature zone to the one control unit;
• wherein the one control unit is operable to simultaneously control the flow of the water to the at least two independent temperature zones through the first outlet of the one pump and the second outlet of the one pump or control the flow of the water to the at least two independent temperature zones sequentially through the first outlet of the one pump and the second outlet of the one pump;
• wherein the one control unit is operable to maintain a target temperature of the first independent temperature zone and the second independent temperature zone via the simultaneous control or the sequential control of the flow of the water;
• wherein the simultaneous control or the sequential control of the flow of the water is governed based on scheduled target temperatures correlating to a sleep cycle of at least one user;
• and
• wherein the at least two independent temperature zones are embedded between the upper layer and the lower layer.
