DETAILED DESCRIPTION

[0027] The embodiments set forth below represent the necessary information to enable those skilled in the art to practice the embodiments and illustrate the best mode of practicing the embodiments. Upon reading the following description in light of the accompanying drawing figures, those skilled in the art will understand the concepts of the disclosure and will recognize applications of these concepts not particularly addressed herein. It should be understood that these concepts and applications fall within the scope of the disclosure and the accompanying claims.

[0028] Last mile delivery of food requires temperature-controlled transport of perishable food items using transit vans or similar vehicles. For temperature control, refrigerated or freezer totes can be used which are installed in the van (e.g., a cargo van) or a box truck.

[0029] These totes use an active heat pump to pull heat from an enclosed chamber and reject it to surrounding ambient air. The hot air must be removed from the van to ensure optimum operation of the totes.

[0030] These totes require power while in transit maintain food safety requirements for perishable consumption. The electrical system needs to reach (and/or maintain) the correct temperature must be met for operation of the totes.

[0031] FIGS. 1A-1D illustrate utilization of a portable, self-contained, refrigeration or freezing system, coupled with integrated automated controls and monitoring.

[0032] FIG. 2 and FIGS. 3A and 3B illustrate an example embodiment of an active cooler in accordance with embodiments of the present disclosure.

[0033] FIG. 4 illustrates a system including an active cooler in accordance with some embodiments of the present disclosure.

[0034] For more details, the interested reader is directed to U.S. Provisional Patent Application Ser. No. 62/953,771, entitled THERMOELECTRIC REFRIGERATED/FROZEN PRODUCT STORAGE AND TRANSPORTATION COOLER; U.S. patent application Ser. No. 17/135,420, entitled THERMOELECTRIC REFRIGERATED/FROZEN PRODUCT STORAGE AND TRANSPORTATION COOLER, now U.S. Patent Application Publication No. 2021/0199353 A1; and International Patent Application No. PCT/US2020/067172, entitled THERMOELECTRIC REFRIGERATED/FROZEN PRODUCT STORAGE AND TRANSPORTATION COOLER, now International Patent Publication No. WO 2021/134068. These applications are hereby incorporated herein by reference in their entirety.

[0035] FIG. 5 illustrates an example of a tote as discussed herein. FIGS. 6A and 6B illustrate that different versions of the totes could be used in refrigerator or freezer versions. FIG. 7 shows an exploded view of the tote that includes a thermoelectric unit as discussed herein.

[0036] FIG. 8 shows the standard tri-temperature truck that is used for deliveries. This might include several different cooling systems that must be carried around regardless of whether they are currently needed.

[0037] FIG. 9 illustrates a delivery truck which does not need refrigeration systems or needs less. In this embodiment, the totes provide the proper temperatures for the various goods. This can make the trucks more efficient in many ways. This also adds configurability. If an entire truck is needed for a specific temperature, this can be easily accomplished as opposed to the standard truck. These trucks might include charging capabilities or other amenities.

[0038] Current vertical storage systems must have an entire enclosure of the entire vertical storage unit by temperature zone to cool or freeze items in vertical storage. An example of this is shown in FIG. 10.

[0039] In some embodiments, power contacts can be placed at the bottom of a shelving or wireless power can be placed in a vertical storage unit (carousel or vertical lift module (VLM)), and totes can be used as micro space for the temperature control for each item or order. On demand cooling by item can be provided, and items can be placed in a vertical storage system that reduces energy using IOT control with on demand cooling and with wireless contacts or power contacts at the bottom of the shelf because there is no longer an obstacle that prevents the totes from being placed on or off the shelf from both directions. This allows for removal and placement of the tote in a vertical system from both sides of the lift. An example of this is shown in FIG. 11.

[0040] In some embodiments, there is a single shelf of consolidated storage for each order no matter the temperature needed by item. An example of this is shown in FIG. 12. In some embodiments, totes provide the micro temperature control of items at any temperature from ?20 C to higher temperatures (can even include heating). In some embodiments, no cooling enclosure is needed for the vertical storage system. In some embodiments, bottom contacts provide power to totes. In some embodiments, wireless charging can provide power to totes. In some embodiments, the tote weight and gravity hold the tote against the power contact. In some embodiments, there are no obstacles on either side of shelf, which allows for access from both sides of the shelf. In some embodiments, access to both sides of the shelf allows access from both sides of the vertical system so you can retrieve or place totes on the shelf from both sides. In some embodiments, IOT monitors the totes for health, temperature and allows for command and control of totes for power and on-demand cooling. In some embodiments, totes using CO.sub.2 and water as refrigerant provide sustainable cooling.

[0041] Those skilled in the art will recognize improvements and modifications to the preferred embodiments of the present disclosure. All such improvements and modifications are considered within the scope of the concepts disclosed herein and the claims that follow.
