Peltier Cooling Box with Phase Change Material (PCM)
Approx. component budget: Rs. 8,000 - 12,000
Objective
Compare cooling time and temperature hold-time with and without PCM, and find COP at different supply currents.
What you will build
Insulated box, 2-3 Peltier modules with heat sinks and fans, 12 V power supply, PCM containers (paraffin or similar) and a temperature logger.
Results you can expect
- Pull-down curves
- COP vs current
- Energy saved with PCM
- Hold-time improvement
What you will learn
Thermoelectrics, thermal storage and energy efficiency. Relevant to cold chain and electronics cooling.
Tools and notes
Arduino + sensors, Excel. Heat sink design matters a lot for results.
Resume points from this project
- Built and tested Peltier Cooling Box with Phase Change Material (PCM); objective: compare cooling time and how long the box stays cold with and without PCM, and find the COP at different supply currents.
- Measured and analysed cooling (pull-down) curves with and without PCM and COP vs current; wrote the report and presented the results in a viva. Add your own numbers: [x].
Replace [x] with your own measured results. Write only what you really did.
