Abstract

Described is a wall design that can set a rapid air circulation inside rooms and can quickly bring down the room temperature to the levels of the outside air temperature. This is achieved by embedding channels of suitable shape in the wall that can act like wind tunnels. Thus the wall becomes an intricate screen. But screened walls would raise privacy concerns, hence the shape of the channels is further modified to become periscope like. As light travels in straight lines, the concern gets addressed. The described system is most suitable even for residential buildings which are generally compartmentalized and have low roofs and where the traditional chimney effect can not work well. To prevent hot air from gushing in during daytime or cold air intrusion during winters, the screened wall is covered with foldable panels on both sides. These panels cover up the screened wall when required. A provision for an insect screen is also provided to keep houses insect free when the wall is screened. An additional water proof panel can be placed on the outermost side of the wall to withstand rains. The covering and opening of the screen is controlled through an intelligent system. The system can even be integrated with home air conditioning system to pre-cool the room to ambient air temperature before turning on the air conditioning system to cool the room further.

WALL DESIGN TO COOL ROOM IN ECO -FRIENDLY MANNER BY REDUCING HEAT ISLAND EFFECT


1. BACKGROUND


1. Apartments or even houses are built with open sides and less common walls as people prefer that because it creates well lit spaces. But light alone does not come in, heat also comes in and heats up all the concrete structures, All the walls, floor, roof get heated very well during the day time.


2. Due to heat island effect, the buildings do not cool well at night. In my personal observation, the difference between outside air temperature and inside room temperature even late into night like 2 AM in Gurgaon is 5-10 degrees. We all know how it feels cool outside, all literature and studies say the same.


3. Even in the hot summer months of May, June, July, August, the average low temperatures in Delhi happen to be 27 to 28 degrees, the same can be seen from the link also - https://en.wikipedia.org/wiki/Climate_of_Delhi


4. Also, AC temperatures at night are set to 25-27 degrees in these months and it feels quite comfortable. This is the reason why people in semi urban areas still sleep outdoors or on house roofs during summer months in North India.


5. This implies that if the heat island effect could be eliminated, then the room temperatures at night would become comfortable naturally and there would not be a need to run ACs, that would lead to huge power saving and green house gases saving also.


6. How nice it would be if the walls of the houses can be removed so that the heat island effect does not exist. But that would lead to security and privacy concerns.


7. The disclosure provides a simple wall design to reduce the heat island effect by generating a natural rapid air circulation system.


2. DETAILED DESCRIPTION


2.1 ROOM WITH FOUR WALLS

ROOM


In the above figure, Blue wall is one wall of the room, wall with green edges is second wall, both are exposed walls , that is, not a common wall. Each of such walls is made of four panels as explained below.If there are multiple walls in a room that are not common walls, then the same four panel design can be used for them also


2.2 ONE WALL MODULE WITH FOUR PANELS


2.3 WALL MODULE WITH FOUR PANELS


1. Panel 1 and Panel 3 and the insect screen are foldable

2. Panel 1 and Panel 3 fold and spread together like two panels of the curtains used on stage, they may also be rolled up and down, so the folding can be horizontal or vertical, but not both at the same time

3. The insect screen is also similarly foldable, but it can be deployed independent of Panel 1 and Panel 3, or it may be coupled with these panels, so when the Panel 1 and Panel 3 or parts thereof are spread, the screen folds, when the Panel 1 and Panel 3 are folded the screen spreads.


4. Panel 2 is the fixed panel, it forms the core of the wall or can be called as the wall itself

5. Panel 2 acts like a screened wall. The larger screens are towards the 35 percent top of the wall. The smaller screens are at the low...
