Background

• In 21st century, air conditioner has become a necessary home appliance.

• Consequences that are becoming more obvious are:

1. the depletion of ozone layer due to chloroflourocarbon (CFC) released to the

atmosphere.

2. high amount power consumption.

• A device which can provide cold air and act as a portable air cooler.

Problem Statement

• Hot climate in Malaysia causes non-air conditioned room to be hotter than normal.

• High amount of chlorofluorocarbon (CFC) is released to the atmosphere.• High amount of power consumption.• Air-conditioner is expensive and it is

unportable.

Objectives

• To introduce a new portable type of air conditioner in the market.

• To reduce the cost of using air conditioner.

• To replace water circulation system in air conditioner

Result and Discussion• Data Collection and Analysis

• Air flows is cooled by 5.5⁰C in 1 hours 30 minutes using peltier.

• The coldness of the peltier depends on the current flows.

• As the time increases, the temperature will be decreased.

Advantages of ECO Thermo Cooler

• Portable with ease of carrying around and operate with present of AC supply.

• Does not produce harmful gases into the atmosphere.

• Low power consumption• Provide instant cold air• Affordable and user-friendly

Recommendations

• Increase the amount of peltier used.

• Ultilize peltier with better specification.

• Enclosed the air flow channel to prevent cold air leakage

• Immerse the heat sink in the water to increase the humidity

Conclusion

• ECO Thermo Cooler is a green and sustainable project without producing any harmful gases to environment.
