How to reduce your room temperature without any AC or other cooling machines ?

You can reduce the temperature of your room if you have the following : 

1.An Aquarium full of fish and live plants 

2.Silica Gel 

3.Dwarf Bamboo Tree 

When you put the above three items in your room just under the window, room temperature will be reduced drastically.

When you put the above three items in your room just under the window, room temperature will be reduced drastically .

Logic :

Heat will always flow from higher to lower temperate region. In summer, outside temperature is more than room temperature. So, heat enter our room and increase the temperature so that an equilibrium can be achieved. But in turn this incoming heat raise the temperature of the room.

During summer air is full of moisture. When the relative humidity is very high we face a sultry condition. 

So to reduce the incoming heat we will need something more cooler than our room. And to reduce the moisture we need something that  can absorb it.

Aquariums are much cooler than our room. The fish in the aquarium cools it further as they are cold blooded. Thus making the adjacent places cooler. You can feel this phenomena by visiting any gift shop.

You will feel that places where the fish tanks are kept are more cooler than the places far away from them, in the same gift store.

Generally our rooms are not as big as the gift store. So a simple rectangular glass tank with some live plants are enough to reduce the room temperature.

If your room is big you need a big aquarium and if small ,general aquariums will serve the purpose.

Silica Gel will absorb the moisture in your room.Place 250 grams of silica gel just beside the aquarium.

More oxygenated air in your room will increase the CI (Comfortability Index) of your room. More Carbon di Oxide will do the opposite. Any plant will consume Carbon di Oxide to make food and release Oxygen as the byproduct. So  a plant in your room will always increase oxygen and reduce Carbon di Oxide and thus increasing the CI.(But the problem is at nighttime plant will absorb Oxygen and release Carbon di Oxide )

Dwarf Bamboo trees can provide release large amount of oxygen in the room.So keep 2 dwarf bamboo tree just beside the aquarium.


Moisture : Absorbed by Silica Gel
Heat : Reduced by Aquarium
CI : Increased by the Dwarf Bamboo Tree.

Even after you place all these, your room will not be as cool as an A.C room . But you will not face the ill effects of the scorching heat and humid conditions that are common in Summer .As moisture is absorbed and the thermo-stat like cooling is done by aquariums ,you can keep A.C out of your house.

Harmful Effects of A.C

  • Freon is a fluorocarbon gas which is nonflammable but releases CFC(reacts with Carbon die Oxide of air) in air which is extremely degradable for our environment.
  • Increase the electricity bill drastically.
  • Creates Noise Pollution.
  • Constant exposure to this artificial cooling can disturb heat balance of our body and often causes cold and coughs.

How do ancient human cool their house ?

Sprout waters on the roof and when the water evaporates it cools the rooms below.It is followed even today in the villages of Rajasthan,Jaipur.

Kings of Jaipur uses jewels and mirrors in the walls and ceiling of their palace to regulate temperature. 'Mirrored and bejeweled ceilings and walls retain warmth or render a room cool as the season demands.'(from Travel Photo Essay: Dreaming of Rajasthan, India by Sujatha Bagal)

An earlier form of air cooling, the wind-catcher (Bâd gir), was invented in Persia (Iran) thousands of years ago in the form of wind shafts on the roof, which caught the wind and passed it through water and blew the cooled air into the building.

The ancient Egyptians were known to circulate aqueduct water through the walls of certain houses to cool them. As this sort of water usage was expensive, generally only the wealthy could afford such a luxury.

Medieval Persia had buildings that used cisterns and wind towers to cool buildings during the hot season: cisterns (large open pools in a central courtyards, not underground tanks) collected rain water; wind towers had windows that could catch wind and internal vanes to direct the airflow down into the building, usually over the cistern and out through a downwind cooling tower. Cistern water evaporated, cooling the air in the building.
