Solar Thermal Water Heater and Moderator by Habab
Project by Habab Idrees
Water storage tanks are generally made up of plastic and fiber. That extensively heats up the whole system in summers and cools it down in winters.
The use of geysers (gas & electric) in winter gives rise to multiple complications.
- Environmental problem
- Waste of money
- Waste of natural resources.
In one year, an 80-gallon (302-liter) electric water heater averages about $500 to run, uses 4,800 kWh of electricity and contributes about 6,600 pounds (2,993 kilograms) of CO2 to the atmosphere
A natural-gas-powered heater does better, but it still accounts for about $400 and 3,900 pounds (1,769 kilograms) of CO2 per year So both geysers are somehow very harmful.
In case of solar geyser, the complications found are
- High upfront cost
- Uncontrolled raise in temperature.
- Competitively less quantity of water is heated.
- (Not to mention geysers are one dimensional, it only heats up the water)
- So my objective was to make a system which is low cost, easy to make and can do both that is keep water temperature moderate and increase the temperature of water.
- My system uses solar energy and greenhouse effect to increase the temperature of water tank in winter and in summer it insulates tank to keep the temperature of water moderate.
- In Short, my system covers all loopholes of (Solar, Electric and Gas) geysers. By using my system we can save our environment, natural resources and money for our better future. Note (I have used chemical tanks for experiment because of limited resources)
The proposal which was in my mind is that a low cost and simple system should be made for plastic and fiber water tanks that can increase the temperature of water in winter and keep the temperature of water moderate in summer.
If success is achieved to control the transference of heat of a water tank, I would be able to develop a system of dual nature. ( Dual nature means a system that can keep the temperature of water moderate in summers and increase its temperature in winters )
There has already been research in my chosen area.
SOLAR GEYSERS (Others Design)
The other people have already made solar water geysers and their design work so well but the main disadvantage of their solar water heating systems is relatively high upfront costs and there system can only warm the water, it doesn’t keep the temperature moderate in summer.
GREEN THERMAL WATER MODERATOR (My Design)
My designed system is totally different. It controls the temperature of whole water tank and the special thing about it that it has dual nature. My design has very low cost and it is easy to make. It only costs $15 to make. Everyone can afford it easily, although the advantages of my design is same as other solar geysers which are already made before but the thing that gives edge to my design is that it can also keep the temperature of water moderate in summer.
WHY MY DESIGN IS BETTER
My design is better because it is more efficient ( it can increase the temperature of large amount of water by increasing the temperature of whole water tank) . My design is cheap and it is so easy to make and most importantly it has dual nature.
ABOUT MY DESIGN
My design is inspired from lotus plant. My prototype has eight movable flaps which can be opened and closed. There is a reflecting paper fitted on these flaps with thermocol sheets so in winter when the flaps are opened all the light that hit the flaps is concentrated on tank, this light then pass through a transparent sheet which creates the green house effect and increase the temperature of water in winter, while in summer when the flaps are closed, the thermocol sheets work as an insulator so it doesn’t allow heat or light to get in and increase the temperature of water and in this way, it keeps the temperature of water moderate in summer and that’s how my project works. (I have used chemical drums as water storage tank for experimenting because of limited resources)
CONTROLLING OF TEMPERATURE
If I want to increase or keep the temperature of water according to my need so I can do it with my system.
FOR EXAMPLE: If I want to increase the temperature of water to 37 degree centigrade so I will open the flaps of my system and wait till it gets to my desired temperature(37 degree), when the temperature of water is reached to my desired temperature(37 degree) so I will close the flaps of my system. Now this temperature of water can be maintained till 4 to 6 hours and that’s how I can control the temperature of water.
To test my project, i took two similar water tanks and placed it on same roof one was with my system and one was like an average tank.
WHEN FLAPS WERE CLOSED
When the flaps were closed, my system was working as an insulator and my aim was to keep the temperature of water moderate . I placed thermometer ( Degree centigrade) in each tank and took reading after every half our. I repeated the same process for three days and the result was
