Choosing The Right Size Capacity Air Conditioner, And Its Importance

Posted By :  Admin  

Are you looking for the best AC in India

Well before you buy an air conditioner for your home read this article as this will help you to find the right size air conditioner unit for your place to get the optimum temperature inside the house. 

When you think about the size of the air conditioner, it doesn't mean its physical dimensions only as AC capacity measured in BTUs (British Thermal Units). One can always wish to have the best efficient air conditioner model and relatively low operating cost, and this happens when you choose an air conditioner after analyzing the dimensions of the area to cool. Before going to opt for an air conditioner, one must calculate the room's size in square feet and multiply the length and width of the room to be cooled.  

This Is How You Calculate The Air Conditioner Size

To get the exact capacity AC, you have to multiply length into the width of the available space and again multiply that total times 25 BTU. This is how you can choose an all-season air conditioner that offers ample cooling whether it is a rainy, humid, or hot sunny days. For example, if the room is 10 feet wide and 10 feet long, the actual room size is 100 square feet. That means 100*25= 2500 BTU cooling capacity air conditioner is the best match for your available size.

People were mostly stuck between the air conditioner size and which one will work better and ended up buying a smaller or larger one. Lower BTU units air conditioners take relatively more time to cool the room, and larger capacity will increase your electricity bill and cool the room faster. Ask yourself: which one offers you better cooling in most minor energy consumption or take help from an authorized air conditioner service to pick the best-suited one.

How A Little Is Never Enough And Too Much Proves Worst

A too-large air conditioner can be overkill as someone considers it bigger for better cooling, but it can never be a wise option. As similar, a too low capacity also is not enough, and you always sort of cooling because of its low BTU unit. So, do a favor and calculate an air conditioner after doing proper measurement to get optimum cooling inside your budget.

Making a blind decision on the basis of someone's suggestions can cost you comfort or put an extra burden on your wallet. To eliminate the chances of choosing the wrong capacity air conditioner with these pro tips, which is designed by some of the most experienced AC engineer's panels. Choosing any model of air conditioner on the basis of BTU unit proves to be value for money purchase.   

The Way You Decide The Air Conditioner Capacity And Model

After choosing the right capacity of the air conditioner, the next is to decide the model as it finds wall-mounted is far better than a window AC because of its rapid and efficient cooling. The wall-mounted air conditioner is usually placed on a slightly higher point than the window as it's better at stirring the inside air and results in better cooling. The distance between the floor and the wall-mounted air conditioner filters air from high point to low and achieves constant cooling.    

The thermostat also plays a vital role in effective cooling as the higher the thermostat, the better an air conditioner achieves cooling. It is also needed to offer a better exhaust to an air conditioner to get fresh air every time and better neutralize the internal temperature and humidity. The recent technology air conditioner has newer features to better adapt to the environment and self-control the cooling and other aspects.

Find The Right AC For You

If you buy an AC with lower tonnage capacity than required, it will consume slightly more energy to offer optimum cooling but surge electricity consumption and minimize the overall air conditioner life. You can face a higher electricity bill in case of buying an air conditioner higher than the required capacity. So, both higher and lower tonnage capacity than needed is proving to be bad for your air conditioner after-sales service as a right capacity air conditioner is best for cost-effective cooling.

How Energy Efficiency Rating Can Make A Difference

At the time of buying energy-efficient AC, the star rating has a crucial impact as the more the star rating, the lesser electricity it consumes. The energy rating will be vital when there is a need to run the AC throughout the day and night; then, a 5-star air conditioner is required to limit the energy consumption. Someone who needs to run AC just for few hours can also go for a three-star rating air conditioner.

  • 1 ton of cooling = 1,000 watts

  • 1.5 ton of cooling = 1,500 watts

  • 2 ton of cooling = 2,000 watts

  • 3 ton of cooling = 3000 watts

Factors Affecting Power-Efficiency Of An Air Conditioner

1. No Of A Person Present Inside The Room

Human body produces a lot of heat during the day to day activities, a room with more than 10 people requires bigger size AC or more than one AC to get sufficient cooling inside the room, whereas a room with fewer people then it will get the same cooling from a single AC. So more people inside the space means more power needs an air conditioner to cool the room and result in an electricity bill.

2. Outer and inner temperature

When the outside temperature is above 40 degrees Celsius, then it takes more power to cool a room rather than 32 degrees Celsius temperature. Similarly, it takes more power to cool any room below 18 degrees than to cool it at 24 degrees Celsius at the same time.

The actual room size: the air conditioners remove all the heat present inside your room as the larger the room, the larger the air inside the room, the more electricity required to cool all the inside air. The total electricity consumed in removing heat around 100 sq. ft room is less than taking out heat from greater than 100 sq. ft room.

3. Other Electrical Appliances In The Room

The electrical appliance in your room generates heat which increases your room's inside temperature and makes your AC make an additional effort for cooling the same volume of air; hence it consumes more power for cooling.

The amount of air to be cooled: Often, we keep the room's door open, which raises the volume of air inside the room and needs to be cooled by the AC. Now your AC has to cool the extra amount of hot air entering the room, which puts unnecessary pressure on the unit and consumes extra power to achieve optimum cooling.

4. Other Objects Present In The Room

Every hard surface in your room gets cold when AC is running; this also consumes some cooling your AC has to do.
