Climate controlled seating assembly with sensors
View Patent ↗According to certain embodiments disclosed in the present application, a climate controlled seating assembly includes a thermal module. The thermal module comprises at least one inlet channel, at least one outlet channel and a thermoelectric device (e.g., Peltier circuit) positioned upstream of the outlet channel. In one embodiment, the seating assembly includes a sensor positioned within an interior of the thermal module and configured to detect the presence of a liquid, such as water, relative humidity, condensation or other fluids, on or near said sensor.
1. A method of controlling a thermal module configured for use in a climate controlled seat assembly, comprising:
providing a thermal module configured to provide air to the climate controlled seat assembly, the thermal module comprising:
an inlet and an outlet;
a thermal condition device configured to selectively heat or cool air passing through or adjacent the thermal conditioning device; and
a fluid transfer device configured to transfer air from the inlet to the outlet and past the thermal conditioning device; and
wherein a controller is configured to regulate at least one operational aspect of the thermal module;
operatively coupling a sensor to the controller, the sensor being configured to detect a relative humidity of air being transferred adjacent the sensor;
wherein the controller is configured to reduce a voltage of electrical energy provided to the thermal conditioning device when the sensor detects a relative humidity level of air being transferred that is above a threshold level to avoid condensate formation;
wherein, when the relative humidity level of air being transferred is below a threshold level, the controller is configured to adjust a voltage supplied to the thermal conditioning device to permit the thermal module to operate according to a control algorithm; and
wherein the control algorithm is configured to operate the thermal module within a target comfort zone, wherein the target comfort zone is based on, at least in part, the relative humidity level and a temperature of air being transferred by the thermal module.
2. The method of claim 1 , wherein the sensor is positioned at least partially within thermal module.
3. The method of claim 1 , wherein the sensor is positioned outside of the thermal module.
4. The method of claim 1 , wherein the seat assembly comprises a seat.
5. The method of claim 1 , wherein the seat assembly comprises a bed.
6. The method of claim 1 , wherein the controller is configured to at least temporarily discontinue supplying electrical energy to the thermal conditioning device when the sensor detects condensate or a relative humidity level of air being transferred that is above a threshold level.
7. The method of claim 1 , wherein the thermal conditioning device comprises a thermoelectric device.
8. A climate controlled seating assembly comprising:
a thermal module comprising at least one inlet, at least one outlet and a fluid transfer device for selectively transferring air from the at least one inlet to the at least one outlet;
a thermal conditioning device positioned at least partially within the thermal module, the thermal conditioning device being configured to selectively heat or cool a fluid passing through an interior of the thermal module;
at least one sensor configured to detect a relative humidity of ambient air entering the thermal module;
wherein the thermal module and the at least one sensor are coupled to a controller, wherein the controller is configured to at least partially reduce a voltage supplied to the thermal conditioning device when the at least one sensor detects a threshold level of relative humidity to avoid condensate formation;
wherein, when the relative humidity level of air being transferred is below a threshold level, the controller is configured to adjust a voltage supplied to the thermal conditioning device to permit the thermal module to operate according to a control algorithm; and
wherein the control algorithm is configured to operate the thermal module within a target comfort zone, wherein the target comfort zone is based on, at least in part, the relative humidity level and a temperature of air being transferred by the thermal module.
9. The seating assembly of claim 8 , wherein the at least one sensor is positioned at least partially within thermal module.
10. The seating assembly of claim 8 , wherein the at least one sensor is positioned outside of the thermal module.
11. The seating assembly of claim 8 , wherein the seat assembly comprises a seat or a bed.
12. The seating assembly of claim 8 , wherein the thermal conditioning device comprises a thermoelectric device.
