What is an ISEER Rating? What is the Best ISEER Rating AC ? What is the best way to evaluate air conditioners? In the recent past, the demand for efficient and energy saving heat and air conditioners have increased in a big way. Many leading brands are offering a wide variety of new models and even advanced technology air conditioners that help one get a better deal and save energy in the process.

What is an ISEER Rating

The best way to find the answer to all these questions is through an electronic brochure from a leading brand and its website. In this brochure, you would be able to find all important information about a particular model such as specifications, benefits, pros and cons, electricity efficiency, noise level, operating modes, warranties, etc. It is important to note that it is different for every brand and model and the ratings vary too. Hence, reading the ratings is a helpful tool, but not a sure shot way to purchase an efficient air conditioner. It is advisable that one should compare the pros and cons offered by different brands and select the one that suits their requirements.

The rating systems are also called ISER Ratings and it refers to energy efficiency, performance, noise level, durability, and availability. These ratings are provided in single and dual AC installation. The single inverter air conditioners are installed in residences or office buildings. The dual inverter air conditioners can be used in commercial establishments like hotels, restaurants and healthcare centers.

There are two types of user ratings; thermal and power-conserving. Thermal inverter ACs allow you to reduce your power consumption. Power-conserving inverters, on the other hand, consume lesser amount of energy yet can maintain your cooling system at a constant temperature. Both types are highly recommended for your air conditioner as they help you save money and energy. However, these types of power-conserving compressors are costlier than the thermal type.

Another type is the variable speed compressor or VSC. This is the most popular type of air conditioner in the market today. With a variable speed compressor, your ACs are regulated depending upon the heat load on the unit. It is recommended to get an energy-efficient VSC model if you wish to get more savings.

These devices are available in different shapes, sizes, and capacities. Before choosing one, it is important to know the cooling capacity needed for your air conditioner. You should also determine the cost of operation and the energy required. Another thing to consider is the tonnage of the blower motor. This is important to consider because the greater the tonnage, the more power produced.

To find the best cooling capacity, it is advisable to look up the internet for reviews. If you have limited budget, look for discount air conditioners with lower prices. It is important to note that the higher rated cooler consumes less energy and a lower rated consumes more energy. The more blower horsepower it has, the more cooling capacity it can maintain. To determine the energy consumption, it is advisable to use the Kill-zone rating. It is also important to check out its compatibility with your electric meter and motor.

If you want to have a steady cool compressor, it is advisable to choose the ISEER rating first. By doing so, you can be sure that you are getting a reliable indoor air conditioning device that is worth its price. It is also recommended to use a remote control to operate this indoor blower. If you use a quiet fan, then you can also enjoy long hours of uninterrupted rest.

An ISEER Rating label will appear on an air conditioner or refrigerator if you’re purchasing one. This allows consumers to calculate their electronic energy efficiency and annual electricity consumption. This rating will be simplified so that you are able to understand it.

ISEER

Indian Seasonal Energy Efficiency Ratio is also known as ISEER. It’s used to power refrigerators and air conditioners.

ISEER Rating

The ISSER Rating gives the Electronic device’s star rating. It is calculated by taking the Cooling Seasonal Average Load (Amount Heat Removed) and then dividing it by Cooling Seasonal Energy Use (1600 hours in Yearly 23oC-43oC).

Calculation of ISEER

ISEER = Ice Seasonal Total Load/Colding Seasonal Energy Use

  • (Year) 1600hours 23c to 43c

ISEER Formula

ISEER=Cooling seasonal total load (CSTL)/Cooling seasonal energy consumption (CSEC).

  • EER Energy Efficiency Ratio is measured in British Units BTU.
  • BTU is the Unit of Temperature. Your AC will convert hot air into cool air in one hour in your room with Ac Compressor Work.

Formula EER

  • EER=BTU/Hour Power Supply (W)0.293w1
  • EER= Heat Removed/Hour in WATT Power Consumed/Hour In Watt

At Similar Humidity: 50%, 26degC Inner, and 45degC Outside
