Abstract

A temperature control system may include a thermoelectric device and one or more solar panels operatively connected to the thermoelectric device. The one or more solar panels may provide solar power to the thermoelectric device. A controller may be operatively connected to the thermoelectric device. A first insulating layer may surround a receptacle and a second insulating layer may include a plurality of channels. The controller may switch the thermoelectric device between an ON state and an OFF state based upon a threshold availability of the solar power. The thermoelectric device may receive forced air convection through the plurality of channels in the second insulating layer to maintain a temperature inside the receptacle when the thermoelectric device is in the ON state and may reduce air circulation within the receptacle to substantially maintain the temperature inside the receptacle when the thermoelectric device is in the OFF state.

First claim

What is claimed is:

1 . A temperature control system comprising:
a thermoelectric device; one or more solar panels operatively connected to the thermoelectric device, the one or more solar panels operable to provide solar power to the thermoelectric device; a controller operatively connected to the thermoelectric device; a first insulating layer surrounding a receptacle; and a second insulating layer including a plurality of channels, the second insulating layer disposed between the first insulating layer and the thermoelectric device; wherein:
the controller is operable to switch the thermoelectric device between an ON state and an OFF state based upon a threshold availability of the solar power; and wherein
the thermoelectric device is operable to:
receive forced air convection through the plurality of channels in the second insulating layer to maintain a temperature inside the receptacle when the thermoelectric device is in the ON state; and
reduce air circulation within the receptacle to substantially maintain the temperature inside the receptacle when the thermoelectric device is in the OFF state.

2 . The temperature control system of claim 1 , further comprising a power connector operatively connected to the thermoelectric device.

3 . The temperature control system of claim 2 , wherein the power connector is operable to provide grid power from a grid power source to the thermoelectric device based upon the threshold availability of the solar power.

4 . The temperature control system of claim 3 , wherein the temperature control system is configured to prioritize the solar power over the grid power based on the threshold availability of the solar power.

5 . The temperature control system of claim 1 , wherein a cold side of the thermoelectric device includes a heat sink operable to adjust a temperature of the forced air convection.

6 . The temperature control system of claim 1 , further comprising one or more fans operatively connected to the thermoelectric device, the one or more fans operable to provide the forced air convection.
