SOLAR AIR HEATER
|
|
|
|
Solar air heater is a device to produce hot air for any industrial or
farmer level drying applications by using freely available SUN, without
using any conventional fuels like electricity, diesel, LPG, firewood, coal,
etc., But It could be coupled with an existing conventional drying systems
like Tray driers, Tunnel Driers, Conveyor Drier, FBD drier and bin drier
operated by conventional fuels to save fuel consumption.
|
|
BASIC COMPONENTS
|
|
1. Solar
Panel
2. Air Blowers
3. Insulated Hot air Ducts
The south facing roof of the factory could be used as a base for the solar
panel. By using existing roof structure, solar base will be fitted
above the roof. Above the base solar panel will be constructed.

|
|
ADVANTAGES:
|
|
1.
|
As Solar Air Heating System is coupled with the existing
roof conditions, there is no need of extra additional space and also bottom
of the solar roof could be used as a processing area and drying area.
|
|
2.
|
It has a flexibility to combine with the existing
conventional drying system
|
|
3.
|
It is possible to control the required temperature to
improve the product quality
|
|
4.
|
As the Solar Panel is being constructed by the non-
corrosive materials it has a longer system life cycle
|
|
5.
|
As It has no moving parts except blower and damper
controllers, it has no major wear and tear
|
|
6.
|
Because of the lowest cost, pay-back period is shorter some
products less than 2 years
|
|
7.
|
System life is more than 20 years without any additional
maintenance
|
|
|
