Owing to the unfathomable surge in temperatures in the recent years, air conditioners have evolved as the primary necessity of people all over the globe. Apart from the seasonal variation prevailing in the entire country, most of the territories in India is majorly blessed with a tropical climate which implies that the temperature is bound to rise to an uncomfortable range. Such unbearable climatic conditions have eventually led to the popularity and increased necessity of air conditioners. However, with the extreme technological advancements and innumerable brands promising the perfect machinery in the market, choosing the best from the rest is a hefty task. The key to buying a sovereign of an electrical appliance is to understand the performance, efficiency, and energy-saving techniques.
Complying with the praiseworthy advancements, air conditioners have recently evolved with impressive inverter technologies that have astonishingly excelled in all the fields of concern. By converting the incident AC current to DC, it has mastered the art of energy-saving which directly reduces the count of electric units burned. As a result, the users are also blessed with reasonable electricity bills. However, some good quality non-inverter ACs might prove to be equally effective. Hence, buyers are always advised to abide by the general guidelines while choosing an air conditioner. The easiest way is to check the star rating which is inversely related to energy consumption. The higher the star rating, the lesser is the energy consumed by the machine which also means greater efficiency.
ISEER is abbreviated of Indian Seasonal Energy Efficiency Ratio. It is also defined as the ratio of heat removed to energy consumed. The basic idea behind assigning the name is the seasonal variation that prevails in the country all year round which also means a varied range of cooling temperature is required. The compressor motor works differently when it has to cool a room with approximately 27℃, while the outside temperature is 30℃ than it would have to when the temperature outside is a scorching 40℃.
What To Check In A Machine?
Majority of the consumers are not acquainted with the technical terminologies and distinguishing an AC on the basis of calculations is not always feasible. However, a brief note is always provided by the manufacturers to assist the buyers with the basic knowledge of the machinery. Besides ISEER, here is a list of details that should be checked as well:
- Rated Cooling Capacity for 100% load
The modified inverter air conditioners possess a varying cooling capacity. For e.g., a 1ton inverter AC has a variable capacity of 0.2-1.2 tons. In this case, the Maximum Cooling Capacity would be 1.2. This is in compliance with BEE which marks ±5% concession for the rated capacity.
- Rated Cooling Capacity for 50% load
Certain manufacturers design air conditioners with 50% energy consumption. This implies that the conditioner is assigned to consume only 0.5 tons if the rated capacity is 1 ton. However, 0.5 does not indicate the minimum value.
- Rated Power Input for 100% Load
The unit of power consumed in watts while the machine is performing at 100% load (rated capacity) is indicated as the rated power input.
- Half Power Input for 50% Load
The unit of power consumed in watts while the machine is performing at 50% load (rated capacity) is indicated as the half power input.
- Cooling Seasonal Energy Consumption
This indicates the total number of watts consumed per year. However, the unit mentioned is usually calculated for a period of 1600 hours and is subjected to variation depending on the seasons and regions it is operating at.
Assigning stars for the performance of air conditioners has been considered as the best as it clearly indicates the efficiency of the device as well as assists the buyers with the quality of the product. The high rated, inverter air conditioners have evolved as the best in matters of energy saving and are also preferred by the mass because of the huge savings in electricity bills.
