3. OVERVIEW
Traditional Air-Conditioning
System typically consumes more
than half of the electricity
consumption of homes, especially
those in the higher income earners.
Need to balance the needs for
comfort against consuming
valuable earth resources.
This system will allay the guilt of
using valuable earth resources to
feed the needs for comfort living
and cause pollution.
COMFORT
POLLUTION

4. BACKGROUND
Since early 2000s, many attempts
have been made to harvest the
sunlight for the use of air-
conditioning system.
However, due to price and also
technology advancement, many
attempts had failed.
The team had collaborated with
manufacturers and carried out
real-life tests and configuration to
achieve the ideal setup for an air-
conditioning system powered by
solar energy.

5. BENEFITS
It will allow the users to pay a
fraction of their monthly
electricity bill for the use of air-
conditioning system.
Able to save thousands of kg of
CO2 generated by utility
companies.
Able to ROI the system within
3-5 years.
Support the GREEN effort to Save
the Earth for future generations.

6. DESCRIPTION
The System consists of the following
components :
Solar/PV Panels
Battery
PV Controller
Indoor Unit (DC Motor)
Outdoor Unit (DC Motor)
It aggregates energy from the Sun, Battery
and the Grid (in this priority order) to operate
the outdoor and indoor units.
Similar cooling operation with traditional air-
conditioning system.

7. CONCLUSION
This is a breakthrough where
it has proven to achieve real
savings, unto 90% savings of
the monthly electricity bill.
Mobile Apps is also available
to show the realtime
utilisation of the energy.
This is a new product after
almost a year of testing had
concluded.
