ENERGY MANAGEMENT AND CONSERVATION WHILE ENSURING COLD-CHAIN COMPLIANCE WITHIN AN ACTIVE COOLING SYSTEM ("ACS") ARRAY OF ACTIVELY COOLED TOTES ("ACTS")
Systems and methods for energy management and conservation while ensuring cold-chain compliance are provided. In some embodiments, a method of operating an Active Cooling System (ACS) includes: determining the operating needs of a plurality of Actively Cooled Totes (ACTs); and adjusting an operation of one or more of the plurality of ACTs based on a physical location of the one or more of the plurality of ACTs in the ACS. In this way, this can prevent mass turn-on of a cluster of ACTs physically close together, generating large columns of hot exhaust air. This can also enable energy savings and prioritization of energy usage.
1 . A method of operating an Active Cooling System, ACS, the method comprising:
determining the operating needs of a plurality of Actively Cooled Totes, ACTs; and
adjusting an operation of one or more of the plurality of ACTs based on a physical location of the one or more of the plurality of ACTs in the ACS.
2 . The method of claim 1 wherein adjusting the operation of the one or more of the plurality of ACTs comprises:
balancing a number of the ACTs operating in pulldown-state with a number of ACTs operating in steady-state.
3 . The method of claim 1 wherein adjusting the operation of the one or more of the plurality of ACTs comprises:
turning on the one or more of the plurality of ACTs in an ordered method based on the physical location of the one or more of the plurality of ACTs in the ACS.
4 . The method of claim 1 wherein adjusting the operation of the one or more of the plurality of ACTs comprises:
balancing a number of the ACTs operating in pulldown-state with a number of ACTs operating in steady-state.
5 . The method of claim 1 wherein determining the operating needs of the plurality of ACTs comprises:
polling the ACTs to determine a current temperature.
6 . The method of claim 5 wherein adjusting the operation of the one or more of the plurality of ACTs comprises:
prioritizing activation of the ACTs with the largest difference between the current temperature and a desired temperature.
7 . The method of claim 1 wherein determining the operating needs of the plurality of ACTs comprises:
polling the ACTs to determine requirements of the goods in each of the ACTs.
8 . The method of claim 7 wherein adjusting the operation of the one or more of the plurality of ACTs comprises:
prioritizing activation of the ACTs with more strict requirements of the goods in those ACTs.
9 . The method of claim 1 wherein adjusting the operation of the one or more of the plurality of ACTs comprises:
adjusting the operation of the one or more of the plurality of ACTs based on a current percentage of occupancy of the ACTs.
10 . The method of claim 7 wherein adjusting the operation of the one or more of the plurality of ACTs comprises:
deprioritizing activation of the ACTs that are empty.
11 . The method of claim 1 wherein adjusting the operation of the one or more of the plurality of ACTs comprises:
adjusting a setpoint temperature of the one or more of the plurality of ACTs.
12 . A controller for operating an Active Cooling System, ACS, the controller comprising at least one processor and a memory, the memory comprising instructions to cause the controller to:
determine the operating needs of a plurality of Actively Cooled Totes, ACTs; and
adjust an operation of one or more of the plurality of ACTs based on a physical location of the one or more of the plurality of ACTs in the ACS.
13 . The controller of claim 12 wherein adjusting the operation of the one or more of the plurality of ACTs comprises being operable to:
balance a number of the ACTs operating in pulldown-state with a number of ACTs operating in steady-state.
14 . The controller of claim 12 wherein adjusting the operation of the one or more of the plurality of ACTs comprises being operable to:
turn on the one or more of the plurality of ACTs in an ordered method based on the physical location of the one or more of the plurality of ACTs in the ACS.
15 . The controller of claim 12 wherein adjusting the operation of the one or more of the plurality of ACTs comprises being operable to:
balance a number of the ACTs operating in pulldown-state with a number of ACTs operating in steady-state.
16 . The controller of claim 12 wherein determining the operating needs of the plurality of ACTs comprises being operable to:
poll the ACTs to determine a current temperature.
17 . The controller of claim 16 wherein adjusting the operation of the one or more of the plurality of ACTs comprises being operable to:
prioritize activation of the ACTs with the largest difference between the current temperature and a desired temperature.
18 . The controller of claim 12 wherein determining the operating needs of the plurality of ACTs comprises being operable to:
poll the ACTs to determine requirements of the goods in each of the ACTs.
19 . The controller of claim 18 wherein adjusting the operation of the one or more of the plurality of ACTs comprises being operable to:
prioritize activation of the ACTs with more strict requirements of the goods in those ACTs.
20 . The controller of claim 12 wherein adjusting the operation of the one or more of the plurality of ACTs comprises being operable to:
adjust the operation of the one or more of the plurality of ACTs based on a current percentage of occupancy of the ACTs.
21 . The controller of claim 20 wherein adjusting the operation of the one or more of the plurality of ACTs comprises being operable to:
deprioritize activation of the ACTs that are empty.
22 . The controller of claim 12 wherein adjusting the operation of the one or more of the plurality of ACTs comprises being operable to:
adjust a setpoint temperature of the one or more of the plurality of ACTs.
