Abstract

An environmental control unit for use with a transport container is disclosed. The environmental control unit includes a thermoelectric device, a fan configured to blow air across the thermoelectric device, a cooling module, a controller in electronic communication with the thermoelectric device and the fan, and a communication module in electronic communication with the controller. The communication module is configured to transmit parameters of the environmental control unit to a computing device through wireless communication. The controller is also configured to determine a present location of the transport container, determine a destination of the transport container, evaluate an internal temperature of the transport container, and control an on or off condition of the thermoelectric device based on the present location, the destination, and the internal temperature of the transport container.

First claim

What is claimed is:

1. An environmental control unit for use with a transport container, the environmental control unit comprising:
a thermoelectric device;
a fan configured to blow air across the thermoelectric device;
a cooling module configured to receive the air blown across the thermoelectric device and convey the air to a compartment of a transport container when the transport container is removably connected to the environmental control unit;
a controller in electronic communication with the thermoelectric device and the fan; and
a communication module in electronic communication with the controller, wherein the communication module is configured to transmit parameters of the environmental control unit to a computing device through wireless communication;
wherein the controller is configured to:
determine a present location of the transport container;
determine a destination of the transport container;
evaluate an internal temperature of the transport container;
determine, based on one or more of the destination, the present location, and the internal temperature, whether a condition inside of the transport container is sufficient to maintain an ideal temperature within the compartment with the cooling module switched off for at least some time during a remaining portion of travel to the destination; and
control an on or off condition of the thermoelectric device based on the present location, the destination, and the internal temperature of the transport container.

2. The environmental control unit of claim 1 , further comprising:
a battery configured to power the environmental control unit.

3. The environmental control unit of claim 1 , further comprising:
a power source configured to power the environmental control unit, wherein the power source is a flywheel generator.

4. The environmental control unit of claim 1 , further comprising:
a power source configured to power the environmental control unit, wherein the power source is a vehicle battery.

5. The environmental control unit of claim 1 , wherein:
the communication module is configured to receive control commands from the computing device; and
the controller is configured to adjust operation of the fan and the thermoelectric device in response to the control command.

6. The environmental control unit of claim 1 , further comprising:
one or more sensors, configured to detect at least one of a temperature of air flowing through the cooling module, humidity of air flowing through the cooling module, and a location of the environmental control unit.

7. The environmental control unit of claim 1 , wherein:
the transport container includes more than one compartment; and
the environmental control unit includes at least one thermoelectric device for each compartment.

8. The environmental control unit of claim 1 , further comprising:
a control panel located on an exterior of the environmental control unit, wherein the control panel is configured to receive input of at least one of a selected temperature for the environmental control unit, a maximum temperature for the environmental control unit, and a minimum temperature for the environmental control unit.

9. A refrigerated transport system comprising:
a transport container;
an environmental control unit removably connected to the transport container, the environmental control unit comprising:
a thermoelectric device;
a fan configured to blow air across the thermoelectric device;
a cooling module configured to receive the air blown across the thermoelectric device and convey the air to a compartment of the transport container;
a controller in electronic communication with the thermoelectric device and the fan; and
a communication module in electronic communication with the controller and wireless communication with a computing device, wherein the communication module is configured to transmit parameters of the environmental control unit to the computing device through wireless communication; wherein the controller is configured to:
determine a present location of the transport container;
determine a destination of the transport container;
evaluate an internal temperature of the transport container;
determine, based on one or more of the destination, the present location, and the internal temperature, whether a condition inside of the transport container is sufficient to maintain an ideal temperature within the compartment with the cooling module switched off for at least some time during a remaining portion of travel to the destination; and
control an on or off condition of the thermoelectric device based on the present location, the destination, and the internal temperature of the transport container.

10. The refrigerated transport system of claim 9 , further comprising:
a battery configured to power the environmental control unit.

11. The refrigerated transport system of claim 9 , further comprising:
a power source configured to power the environmental control unit, wherein the power source is a flywheel generator.

12. The refrigerated transport system of claim 9 , further comprising:
a power source configured to power the environmental control unit, wherein the power source is a vehicle battery.

13. The refrigerated transport system of claim 9 , wherein:
the communication module is configured to receive control commands from the computing device; and
the controller is configured to adjust operation of the fan and the thermoelectric device in response to the control command.

14. The refrigerated transport system of claim 9 , further comprising:
one or more sensors, configured to detect at least one of a temperature of air flowing through the cooling module, humidity of air flowing through the cooling module, and a location of the environmental control unit.

15. The refrigerated transport system of claim 9 , wherein:
the transport container includes more than one compartment; and
the environmental control unit includes at least one thermoelectric device for each compartment.

16. The refrigerated transport system of claim 9 , further comprising:
a control panel located on an exterior of the environmental control unit, wherein the control panel is configured to receive input of at least one of a selected temperature for the environmental control unit, a maximum temperature for the environmental control unit, and a minimum temperature for the environmental control unit.

17. The refrigerated transport system of claim 9 , wherein:
the computing device is configured to display parameters on a map though a graphical user interface.

18. A method of managing environmental conditions within a refrigerated transport system through a computing device, the method comprising:
determining, via a processor in the computing device, a present location of the refrigerated transport system;
determining, via the processor, a destination of the refrigerated transport system;
evaluating, via the processor, an internal temperature of the refrigerated transport system;
determining, based on one or more of the destination, the present location, and the internal temperature, whether a condition inside of the transport container is sufficient to maintain an ideal temperature for an item being cooled by the refrigerated transport system with the cooling modules switched off for at least a portion of time during travel to the destination; and
