Air conditioners have become one of the most important aspects of our everyday lives. However, there are several questions which can leave almost every person confused.

Watt of 1 ton AC? What are the stars? What is the concept of the ton? What is the power consumption and how to calculate? What is 1-ton AC watt? Most importantly, which air conditioner is best suited for him or her personally? All these questions cloud one’s mind, relying completely on a professional to give them an honest opinion and thus, technically having almost no idea of their own. This inability to understand and choose what’s best for them on their own is something that bothers a lot of people, who then take it to the internet and yet are hounded with innumerable scattered explanations for the same. They look at manuals and charts and find explanations according to part and in other places, it’s all calculations and deduction mechanisms teaching him or her to understand the results and usage of the machine he or she wants to obtain.

# Watt of 1 ton Ac – Understanding the Power Consumption

Understanding the functioning of an AC can be tedious but not everybody needs to go into the inner details. A bit of basic understanding can go a long way to make his or her own choice in choosing the machine of their requirement.

Here, we are going to look at each term carefully and understand what they stand for.

**BTU**

BTU (British Thermal Unit) is a unit used to understand the energy required to increase the overall heat of a unit of water by just a scale, although the calculations can be made in other units and measurements. This measurement is very popular because of the standard used across the globe and while better measurement units have come up, this one sticks to all such measurements to date.

Now, in relation to ACs, BTU score of the machine can be used to immediately get an idea of how much cooling the air conditioner can get done and how fast usually considered in a unit of each quantity measurement for the ease of the purpose. If the British Thermal Unit score of an air conditioner is high, it generally means that it can cool the same area in less time or more area in the same 1-hour span. However, at the same time, this does not mean one can get a very high score air conditioner for a very small room, with the idea that it will cool the room much faster since this might become counterproductive and create additional issues.

Usually, a quite small room should have an air conditioner with a BTU of 6000 to 8000.

The score for very large rooms can go up to about 30,000, like for large apartments, in which case a 28,000 to 30,000 is more than enough, if not slightly above requirement.

**Ton**

The ton is a major question that is related to the machine since it dictates the capacity and the functioning ability of the AC in specific locations and for varied areas. It is calculated on the basis of the area the machine is required to work and vice versa.

Now, as mentioned above, the tonnage of the AC is essential to understand the amount of cooling to be done and the time required for it depending on the area. Like a jigsaw puzzle, each piece filling a particular gap, a particular ton AC is the best suited for a certain type and area of location that it needs to fit in so that it can give the maximum and most smooth result.

If calculated, in short, a 1-ton air conditioner has a BTU score of 12,000. This is a set value. Hence, if a person decides to purchase an air conditioner with a BTU score of 24,000, he or she can choose a 2-ton ac. Usually, for one small to a medium-sized bedroom, one can even choose a half-ton ac.

Like any other machine, overdoing or underdoing a function can spoil the very insides of the AC. If a small ton AC is used to cool a huge area, it will not only require a large out of time but it will come with the possibility of the inner circuits getting burnt due to the overworking or stress it has to go through, interestingly just like humans. Similarly, a large ton AC in a small room will produce adverse effects that what is desired. Hence the best choice would be to find the best size according to requirements.

**Energy Efficiency Ratio and the Seasonal Energy Efficiency Ratio**

The former is nothing but what is usually indicated while speaking of the EER and the latter the SEER.

Energy Efficiency Ratio is the ratio between the British Thermal Unit score of a machine per hour to the input of power. This is usually calculated at a constant temperature.

The equation can be stated as,

**Energy Efficiency Ratio = Btu score in hour/ input of energy**

This can be easily used to calculate the EER if the other two values are known or either value can be calculated if the other two are known.

Seasonal Energy Efficiency Ratio on their hand is basically the same ratio as EER, just over a number of days, over a range of temperature and not one single temperature like the latter. As a result, it is more preferred as it can give or indicate the exact wattage of the air conditioner if the BTU and SEER are known. One can get a better idea since the energy consumed by the machine changes from location to location, depending upon the amount of heat.

The stars, that can be seen to categories air conditioners are used to signify the EER or more efficiently the SEER value of the machine.

**Wattage**

This is one of the most important factors that account for an AC because the amount for the air conditioner in the electricity bill can be calculated from here, beforehand.

It is the energy required to run the air conditioner for an hour. Thus, if the value for an hour is calculated, one can easily calculate the total value by multiplying the one-hour data with the total number of hours it has been running for and gets the total value.

A 1-ton AC watt is about 3.5-kilowatt usually, although it completely depends on how many stars the AC is and hence it’s SEER or EER value.

Considering the above equation and information, we know that a 1-ton AC has a BTU score of 12,000. If it has a Seasonal Energy Efficiency Ratio ten, then we have a wattage of about twelve hundred.

Thus a 1-ton AC watt, having a SEER 10, will be twelve hundred. As the SEER value changes, the power consumption will change thus altering the 1-ton AC watt.

To calculate the bill, which is completely dependent on the wattage, one has to calculate the value in kilowatt, then multiply the hours of functioning and the cost per kilowatt. Also, this calculation can help understand, the maximum possible power consumption, since the value can reduce depending upon the hours of working, area to be worked on and the overall heat in the area.

A 1-ton AC watt in a comparatively cold place will be lesser than that of a warmer place, because of the change in SEER value.
