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. 8. 0 Engineering Analysis Power Distribution No Component Voltage Current Power (V) (A) (watt) 1 Upper fan 12. 0 0. 18 2. 16 2 2 side fan 12. 0 each 0. 18 each 4. 32 3 Bottom fan 12. 0 0. 50 6. 00 4 Bulb 12. 0 1. 50 18. 00 Total Power Used (watt) Electric tariff (TNB): RM 0. 34/kwh Total power usage: 30. 48 watt* 0. 75 hour* RM 0. 34/kwh= RM 0. 08 per usage 30. 48 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. Our drying wardrobe utilizes the evaporation process, with fan and heater work complimentary to each other, that is safe to operate and reliable and will be a revolutionary way to dry clothes.
