Introduction An air conditioner is a device that provide heating and cooling to the air temperature. The aim of distributing the conditioned air to an occupied space such as a building, house or vehicle to improve thermal comfort and indoor environment quality. Replacing the air conditioners having poor IEQ (indoor environment quality) with better IEQ is the aim of this project.

Adverse effects on environment

1.Global warming2.Negative health effect3.Contribute to pollution4.Cause acid rain5. Releasing poisonous gases Air conditioner use in the U.S. results in an average of about 100 million tons of CO2 emissions from power plants every year.

Energy efficient parameters

The terms COP (coefficient of performance) and EER (energy efficiency ratio) describe the heating and cooling efficiency of air conditioners. They indicate the ratio of heating or cooling provided by a unit relative to the amount of electrical input required to generate it. Thus, if an air conditioner generates 5kW of heat from a 1kW electrical input, its COP is said to be 5.0. Similarly, if an air conditioner generates 5kW of cooling from a 1kW electrical input its EER is also said to be 5.0. Higher the COP and EER, the more energy efficient is the equipment.

New methods

Method-1:-

By circulating the cold or heat water through the pipes arrangement placed just below but attached with the roof at 0 degree orientation so that water will flow with high pressure energy by using pumps and tanks which already exist in the building.

Method-2

Geothermal heating and cooling system- Unlike ordinary heating and cooling systems, geothermal heating and cooling systems do not burn fossil fuel to generate heat; they simply transfer heat to and from the earth. Typically, electric power is used only to operate the unit’s fan, compressor, and pump.

Performance COP & EER may increase up to 8- 9 . They use 25% to 50% less electricity

than conventional heating or cooling systems.

It also improves humidity control by maintaining about 50% relative indoor humidity, making GHPs very effective in humid areas.

Geothermal heat pump systems allow for design flexibility

Advantages

1.Energy efficient2.Economic3.High life span4.No health effect5.Contributing less to pollution6. Little maintenance

Conclusion

To protect our planet as well as the human being from the adverse effect of air conditioners, we must have to go for green concepts which provide high COP & EER along with fair environment.
