3. For Constructed Homes For Summer In summers usually the temperature inside the house is less than the temperature outside the house. In summers usually the temperature inside the house is less than the temperature outside the house. Cooling inside air proves to be more effective than cooling the outside air. Cooling inside air proves to be more effective than cooling the outside air. The energy utilized for cooling inside air is much less than that used to cool outside air The energy utilized for cooling inside air is much less than that used to cool outside air 3

4. Eco Friendly Power Saver AC These 2 diagrams shows all the component of the AC from 2 different sides that is above view and front view 4

5. Eco Friendly Power Saver AC Description This project is made by me and it is currently in prototype stage This project is made by me and it is currently in prototype stage This AC is cheap in compare to other AC currently present in the market. This AC is cheap in compare to other AC currently present in the market. This AC requires vey less electricity as the only electric appliance in this AC is Exhaust Fan which require very less electricity to work This AC requires vey less electricity as the only electric appliance in this AC is Exhaust Fan which require very less electricity to work This AC is eco-friendly as it does not emit any harmful gas in the environment This AC is eco-friendly as it does not emit any harmful gas in the environment This AC cools the air present inside the room that is why it works more efficiently This AC cools the air present inside the room that is why it works more efficiently 5

6. Eco Friendly Power Saver AC Working 1. Inside the delivery tube an exhaust fan is placed at one end which is placed at the window of the room. The second end of the tube is placed in another window of same room. 2. When room air enter the tube through exhaust fan it comes in contact with the glass bottles that are filled with concentrated ammonium chloride 3. The heat of air is absorbed by the cooling agent that is ammonium chloride. 4. Then this cool air passes through fiber glass cotton/ cotton wool placed inside net with space so that air can come in contact with glass pieces of the wool/cotton. 5. The glass pieces further cools the air by reducing its temperature by 7-11 degree Celsius 6

7. Continue….. Working 6. Since the concentrated ammonium chloride would be filled inside a Air tight glass bottles therefore it will work more efficiently and would never get exhausted. 7. Since the Tube would be covered with thermocoal sheets, the sheets would works as an insulator and the inside temperature of the tube would not affected by the heat present in its surroundings. Ammonium Chloride: Ammonium chloride is a volatile substance and it absorbs the heat energy from its surrounding and evaporates causing cooling at that place.

Fiber Glass Cotton : Fiber glass cotton contains glass pieces which increases the cooling effect. Fiber Glass Cotton : Fiber glass cotton contains glass pieces which increases the cooling effect. Exhaust Fan : Exhaust fan transfers the air from room to AC Exhaust Fan : Exhaust fan transfers the air from room to AC 7

8. For Constructed Homes For Winters In winters usually the temperature inside the house is more than the temperature outside the house In winters usually the temperature inside the house is more than the temperature outside the house If the inside air is heated then it will prove more effective than heating the outside air. If the inside air is heated then it will prove more effective than heating the outside air. The energy utilized for heating inside air is much less than that used to heat outside air The energy utilized for heating inside air is much less than that used to heat outside air 8

Power saving Heater Description This project is made by me and it is currently in designing stage This project is made by me and it is currently in designing stage This heater is cheap in compare to other heaters currently present in the market. This heater is cheap in compare to other heaters currently present in the market. This heater requires vey less electricity as it only uses a single Exhaust Fan during day which require very less electricity to work and an exhaust fan and 6-8 15 watt bulbs at night. This heater requires vey less electricity as it only uses a single Exhaust Fan during day which require very less electricity to work and an exhaust fan and 6-8 15 watt bulbs at night. 10

11. Power Saving Heater Uses of The Components 15 watt bulbs: They will work as an artificial source of heat energy during night. 15 watt bulbs: They will work as an artificial source of heat energy during night. Plane Mirror: Plane mirror will create a greenhouse effect. Thus, increasing the temperature of air and making it hot. Plane Mirror: Plane mirror will create a greenhouse effect. Thus, increasing the temperature of air and making it hot. Concave mirror: Concave mirror works as a converging mirror and concentrates the parallel rays of the sun at a point. Thus increasing the temperature. Concave mirror: Concave mirror works as a converging mirror and concentrates the parallel rays of the sun at a point. Thus increasing the temperature. Sand: Sand gets heated up quickly. Therefore it gets heated up by the heat rays of the bulb. Thus proving to be very effective especially at night in increasing the temperature. Sand: Sand gets heated up quickly. Therefore it gets heated up by the heat rays of the bulb. Thus proving to be very effective especially at night in increasing the temperature. Black Coloured Foam: Black colour absorbs maximum heat as compare to other colours. Black Coloured Foam: Black colour absorbs maximum heat as compare to other colours. Note: The main heater structure is placed inside a wooden box open from up to provide insulation to heater from outside temperature. 11

12. Working During Day 1. Inside A delivery tube an exhaust fan is placed at one end which is in room. The second end of the tube is placed in same room. 2. When room air enter the tube through exhaust fan it comes in contact with the black coloured foam. 3. Since the colour of foam is black it will absorb the heat during the day and when air will come in contact with foam the air will absorb heat energy from it. 4. Then this Hot air passes through sand placed inside the heater. It will absorb the heat from sand and will become more hot. 5. Then this hot air will absorb the heat that is stored by the glass rod. 6. In this way the temperature of air will increase by 8-15 degree Celsius. 12 Power saving Heater

13. Power Saving Heater Working During Night During the night since there is no sunlight therefore there is a need of artificial source of heat. During the night since there is no sunlight therefore there is a need of artificial source of heat. The bulbs release heat energy that is used by sand, glass rod and black coloured foam to store heat energy in them The bulbs release heat energy that is used by sand, glass rod and black coloured foam to store heat energy in them This energy is then used by air to get heated and increase the temperature of room. This energy is then used by air to get heated and increase the temperature of room. 13

14. For building to be constructed Passive Solar Building In passive solar building design, windows, walls, and floors are made to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design or climatic design because, unlike active systems, it doesn't involve the use of mechanical and electrical devices. The key to designing a passive solar building is to best take advantage of the local climate. Elements to be considered include window placement and glazing type, thermal insulation, thermal mass, and shading. Passive solar design techniques can be applied most easily to new buildings, but existing buildings can be adapted or "retrofitted".
