pannel on climatic zone of india

1. CLIMATIC ZONES OF INDIA
Regions having similar characteristic
features of a climate are grouped under one
climate zone. Predominantly, Indian
subcontinent is divided into five climate
zones-
1. HOT AND DRY.
2. WARM AND HUMID.
3. COMPOSITE
4. TEMPEARTE
5. COLD
CHARACTERISTICS OF WARM AND HUMID
CLIMATE
•Warm and Humid climate is characterized
by high relative humidity(around 70-90 %)
•Precipitation levels (about 1200 mm per
year.)
•The temperatures usually vary between 25–
35 ºC in summers; while in winters,
temperatures vary between 20–30 ºC.

The building design
in this climate
should aim at –
•Reducing heat gain by
providing shading
•Promoting heat loss by
maximizing cross
ventilation.
• Dissipation of humidity
to reduce discomfort.

WHAT IS PASSIVE DESSICANT COOLING SYSTEM?
It is a method that removes
moisture from the air which
decreases the relative
humidity. The moisture is
removed by passing the air
through a material called a
desiccant. As the desiccant
absorbs the moisture from
the air, it becomes saturated
and loses its ability to
continue absorbing
moisture. At this point, the
desiccant is then
regenerated, or dried, with
solar heat which evaporates
the moisture into the outside
air. It is then ready to absorb
more moisture from the air
entering your home.
