A recently granted patent (Publication Number: US11913695B2) discloses an innovative ice-lined vaccine refrigerator designed to maintain a consistent temperature range in the vaccine storage compartment. The refrigerator features an electrically powered cooling circuit with a DC powered compressor that is powered by an external AC power supply through an AC power inlet. An AC/DC converter housed within the refrigerator converts the AC power to DC power to operate the compressor efficiently. Additionally, the compressor and converter are designed to operate within a wide range of AC power inputs, making it adaptable to various electrical grid supplies without the need for a voltage stabilizer.

Furthermore, the patent details the inclusion of an overvoltage protection relay to safeguard the system from voltage spikes, ensuring the longevity and reliability of the refrigerator. The innovative design also allows for the selection of power sources for the compressor, including AC power from the grid, DC power from an external source, or a combination of both. This flexibility in power sources enhances the refrigerator's usability in different settings, including areas with unreliable electrical grid supplies. Overall, the ice-lined vaccine refrigerator aims to provide a sustainable and efficient solution for storing vaccines within the optimal temperature range, ensuring their efficacy and safety for extended periods.
