Abstract
In some embodiments, systems and methods are provided that limit the change in temperature and/or control a temperature of a product during delivery. Some embodiments provide systems to limit temperature changes, comprising: an evaporative product cooling system comprising: a product cavity that supports a product while the product is transported to a delivery location, wherein the product cooling system comprises an interior wall defining the product cavity, an exterior wall, an evaporative cavity between the interior and exterior walls, a coolant dispensing system, at least one evaporative opening, and a temperature sensor; and a temperature control circuit configured to receive temperature data from the temperature sensor while the product is in transit, determine that a temperature of the product is greater than a transport temperature threshold, and autonomously activate the coolant dispensing system to release evaporative coolant into the evaporative cavity while the product is transported.
