Increasing the air flow rate in it. 2. Decreasing the humidity inside it by rapidly removing the water vapour. 3. Rising up the internal temperature by rapid circulation of heat throughout the wardrobe. Total Power Used (watt) 35. 28 9. 0 Advantages Benefits that we can reap from it: 1. Two functions in one wardrobe. Switch on to dry the clothes. Switch off to store the clothes. 2. No hassle as this wardrobe can be plugged in or run on battery. 3. Easy placement in limited indoor spaces, user friendly and does not depend on weather conditions 10. 0 Conclusion & Recommendations Few recommendations are suggested to improve our prototype which are: 1. Replace existing fans with a bigger fans. 2. Collapsible clothes dryer that operates remotely with portable battery bank. 3. Proper exhaust to promote rapid air circulation and more efficient heating device.
