เครื่องทำน้ำอุ่นด้วยโครงสร้างอย่างง่าย

Abstract

This project studies the solar energy used in water warming system which is consisted of primary functionally theory and calculation of water warming system design. The solar water heater will use a solar plate sized 2 squaremetre to transfer the heat and increase the temperature of water. That created the grate are 45 rows non-grade iron cast having 2 centimetre, diameter and paint in black color in order to absorb more solar energy. Five millimetre thicked glass will be taken to cover at the top. Next apliance is tank.That is able to keep the 250 litre water and cover with fiber glass insulate all around to protect the heat spreading. We use water in the amount of 250 litre and heat its temperature reaching to 60°C 10 hours. We Choose to record the test around 8.00 am. - 6.00 pm.
