Abstract: This project presents the design and implementation of a thermoelectric cooling system based on the Peltier effect, intended for the storage of temperature-sensitive pharmaceutical compounds.The core component, a TEC1-12715 Peltier module, facilitates heat transfer across two junctions upon application of direct current, generating a cold side suitable for medicinal storage and a hot side managed through an integrated heat sink and BLDC fan assembly.The system architecture in corporates a dual power supply configuration, where in the Peltier module is driven by a Switched Mode Power Supply (SMPS) and the BLDC fan is operated via a DC adaptor, ensuring stable and independent thermal regulation of each subsystem.A deliberate sequential startup protocol -initiating fan operation prior to Peltier module activation -is employed to minimize transient thermal stress and enhance overall system reliability.The design prioritizes compactness, noiseless operation, and environmental sustainability, positioning it as a viable alternative to conventional vaporcompression refrigeration systems, particularly for portable and small-scale applications.System performance is evaluated based on the rate of temperature reduction and the stability of the maintained thermal environment over time.In conclusion, the proposed thermoelectric cooling system demonstrates effective and eco-friendly thermal management for medical storage applications, validating the practical deployment of solid-state thermoelectric principles and identifying a clear pathway for future advancements in compact cooling technology.
