US 2024/0191916 A1 · Medical Grade Freezer for Vaccines and Medications

Abstract

A medical grade cooler or freezer uses a Peltier system without the use of vapor compression refrigeration. An opening may be cut through a wall, for example, a top, bottom, rear or side wall, of the cooler or freezer and the Peltier device sealed within that opening with the hot side exposed outside of the cooler or freezer and the cold side exposed inside the cooler. When a voltage is applied to the Peltier device, the interior temperature of the cooler may be reduced. The Peltier devices can also be reversed by applying voltage in the opposite direction to remove heat from outside of the cooler and pump heat into the cooler or freezer.
