Save Energy through Efficient Air conditioning

Energy saving air conditioners are eco-friendly and keep an increasing electricity bill under control within reasonable limits.

Efficiency: When choosing between units with similar prices, capacities and features, energy efficiency should be the deciding factor. Even though an energy efficient unit may be higher priced, it may be the best to buy. High efficiency appliances cost less to operate and can pay back the extra initial cost many times over during their lifetimes. All room air conditioners bear bright yellow Energy Guide labels which provide information on energy efficiency. The label displays an energy efficiency rating (EER) in large black numbers. The higher the rating, the more efficient is the appliance. Units with an EER of 9.0 above are considered very efficient. To help compare units a range for competing air room conditioners of the same cooling capacity is printed on the Energy Guide label below the EER.

The label also provides a cost/use chart to calculate the cost of operating the appliance based on local electricity rates and expected hours of use.

Central air conditioners are rated according to their Seasonal Energy Efficiency Ratio (SEER). Like the EER, the higher the SEER, the more efficient the system. To compare the efficiency of two units with equal cooling capacity take the difference in SEER and divide by the large SEER.

Among the key customer requirements, energy efficiency is the most important one. Bureau of Energy efficiency, under government of India had introduced Star ratings for electrical appliances. Although this is not made mandatory Voltas is the first company to introduce these star rated energy efficient air conditioners in Indian market. More the number of stars more the energy efficiency and hence the savings. Voltas has also introduced new range of Vertis Panache air conditioners which runs on DC inverter technology which saves more than 50% of energy consumption under test conditions.

Taxes and duties should be lowered: Regular healthy power should be available at reasonable rates. Energy labeling should be made mandatory in the best interest of consumers and the nation.

Air conditioning does more than cool the air. It truly ‘conditions’ it by removing dust and dirt as the air is drawn through a filter. Air conditioning also lowers the humidity, making the air more comfortable at any temperature. These benefits, however, can be costly. Depending on region of the country, air conditioning can account for anywhere from 5 to 50% of household budget. Because an air conditioner is such a sizable investment, you can save money and energy by carefully purchasing and operating air conditioners.

When shopping for an air conditioner, first consider what system best suits your needs –central air conditioning or room air conditioning. Central air conditioners are located in one part of a building, but they pool the entire buildings either by blowing cold air through ducts positioned in each room, or by circulating cooled water through pipes to each room where fans blow air across the pipes. Room air conditioners work in the same way, but have a smaller capacity and therefore only cool the immediate area. Central air conditioners generally provide the greatest comfort but they also cost more than room units. If several rooms need to be cooled, however, a central system is probably the best to buy. Central systems generally are not cost effective as an addition to an existing home unless the existing ductwork can be used.

Room conditioners are mounted in windows or built into an external wall. Room units are less expensive than central units; however, they only cool the general space in which they are located. There are three types of room units; window models can be installed in most windows, casement window model used in narrow, vertical windows usually require the removal of a window panel for installation; and built in models which are encased in a sleeve in the wall.
