PORTABLE COOLING COMPARTMENT FOR STORAGE OF MEDICATION

This is a project on development oftemperature balancing circuit. The objective of
this project is to monitor the temperature of a confined space and keep it at a preset
value 10°C. The scope ofstudy covers the microcontroller circuit used to monitor the
input by the temperature sensor and give output signal to current amplifier circuit to
the peltier device. It also covers the current amplifier circuit and container design to
maintain the temperature. Other important components of the system also include
heat transfer concept, DC Fan, heatsink and insulation material. Experiments on the
peltier device have been performed and its characteristics have been studied. High
power with good insulation and heat removal system are most important on the matter
of increasing the performance of the peltier. Prototype of the project has been
constructed and tested and worked according to specification of cooling the container
uptolO°C.
