Choosing the right capacity of the air conditioner?

What is tonnage?

You can come across different types of ACs with 1, 1.5, 2 and 5 tonnages. What does a ton mean? 1 ton refers to the quantity of heat needed to melt a ton of ice in a day. The standard quantity is 288,000 BTU or British Thermal Units. What does it mean? If you have a one-ton AC, it is going to use 12000 BTU (288,000/24) from a room within one hour. If the tonnage of your AC is 2, it utilizes 24, 000 BTU in an hour.

Important factors that influence the capacity of the air conditioner

The most important factor is the ambient temperature of the surrounding air. The second factor is the volume of the room. You also have to consider the quantity of furniture fitting before deciding on the capacity of the AC.

Ambient temperature

If you are living in a place where summers are really hot and the temperature may reach around 45 C, you have to buy an AC with a higher tonnage compared to cooler places with reasonably hot summers. You can buy an AC with a lesser tonnage if you are living in a place with a colder climate.

Room volume

The volume of the room is an important consideration. As the room size increases, your air conditioning system has to cool more air volume. The cooling effect needs to be properly maintained as well. This aspect makes an impact on tonnage.

The amount of furniture and fittings available in a room

When you decide to buy the right tonnage air conditioner, you have to check the quantity of the furniture and fittings available in your room. Heat gets trapped in the air as well as the things placed inside the room. If you have an empty room, it can be heated with less tonnage. The ton of the AC needs to be higher if the room contains a lot of furniture, carpets, computers and other types of items. Also, the presence of a desktop computer can make the room dramatically warmer.

What capacity or how much ton air conditioner you should buy?

You have to take into consideration all these factors while deciding on the capacity or tonnage of an air conditioner. It is also necessary to focus on a few more important aspects. The heat available in the apartments on the topmost floor is higher compared to other floors below. The presence of warm air, as well as the heat transfer by conduction from the roof, makes topmost floors hotter. If you are planning to buy an AC for an apartment located on the topmost floor, you have to go for a larger one with high tonnage.

If you analyze the conditions in India, you can find that a one-ton AC is capable of cooling a small room with a size of 10 feet ×10 feet or around 100 square feet with 2 people. As far as a 1.5 ton AC is concerned, it can cool a room with a size of 10 feet × 15 feet or around 150 square feet with 4 people reasonably from 35 degrees Celsius to 22 degrees Celsius. The bottom line is that a 1 ton AC is a good choice for a small room. For medium-sized rooms, you need 1.5 ton AC. If you want to cool large rooms including halls, you have to opt for 2 or 3 ton AC.

Electricity consumption of the air conditioners

You need to have a clear idea of how much electricity an AC consumes. It is one of the most important aspects each AC buyer should know. The power consumption of an AC depends on a good number of factors such as star rating, tonnage, and usage.

Star rating

The star rating gives you a clear understanding of the electricity consumption of the air conditioner. The agency that provides the star rating is BEE (Bureau of Energy Efficiency). Air conditioners with higher star ratings can be described as more energy-efficient options available on the market.

How do the BEE Star ratings work?

BEE star rating refers to the ratio between an air conditioner’s cooling ability measured against the electrical input in watts. As mentioned above, a one-ton AC comes with a capacity of 12,000 BTU per hour. You need to understand that 1 BTU/hour is 0.29307107 watts. So the 12,000 BTU every hour can be converted to 3516 watts. The efficiency of a 1 on AC with an input of 1100 watts of power stands at 3516/1100. It is represented as 3.2. This figure places an air conditioner somewhere between a 3 Star and 4 Star AC.

How can you know about the number of stars that represent a 2.9, 3.2 or other similar decimals? You can visit the website of the BEE to get the latest updates. Continuous upgrading is done at regular intervals. The important thing is that a 5-star rating in 2017 becomes a 3-star rating in 2020. You can check the BEE website to get a fair idea of ISEER (Indian Seasonal Energy Efficiency Ratio). It is a measurement launched by BEE in 2016.

How much star AC I should purchase?

When you buy the best air conditioners in India, you have to focus on the annual units consumed. Based on your needs, you can buy one with a higher star. However, you have to make sure that the model is current. It is foolish to pay a premium for a 2016 5 Star AC model. The current rating of such a model is probably a 3 Star. When it comes to choosing between a 3 star AC for 35000 and a 5 star AC for 45000, you need to take into consideration the expected longevity of the equipment and amount of usage. A clear understanding of the lifespan and hours of running helps you decide on how much the additional power cost can be covered by the 10,000 savings.

What is an inverter air conditioner?

Everybody talks about inverter ACs nowadays. What is an inverter AC? It is an air conditioning system that works on Inverter Technology and helps the user save an appreciable amount of power. The compressor of an inverter air conditioner works on variable speeds i.e. it can increase or decrease its capacity according to the cooling requirement of the room.

Difference between fixed speed AC and inverter AC

The compressor of a fixed speed AC works in full swing when it is switched on. Once it reaches the optimum temperature, the compressor stops functioning and the fan keeps on working. When the temperature reaches beyond the threshold limit, the compressor takes over and starts functioning again at full capacity. The fact of the matter is that the compressor of a fixed speed AC functions only at two speeds.

An inverter AC works differently. The compressor of an inverter AC works at variable speeds. This technology does not allow the compressor to switch off and keeps it at ON mode at varying speeds. The power consumption is controlled efficiently because of the varying speeds. The inverter technology can be termed as a power-saving feature that is found only in the split AC models.

Benefits of inverter technology

Are you planning to buy one of the best air conditioners in India? You can certainly consider purchasing an inverter split AC from a leading brand. The biggest advantage of choosing an inverter AC unit is high energy-efficiency. A 3-star inverter AC performs on the same level of a 5-star normal split AC. The ability to run at variable compressor speeds and tonnages based on the heat inside the room is what makes the inverter technology in an AC truly superior. Various studies show that the overall efficiency of inverter AC units is 7% higher compared to standard models with the same star rating.

Other advantages of inverter technology are:

Maintaining constant room temperature

Efficient cooling and heating

Highly suitable for large as well as small rooms

High-quality refrigerants of inverter split AC models make them environmentally-friendly

Disadvantages of inverter technology

Power consumption increases if your room is not properly insulated

The cost of inverter split ACs is higher compared to standard models

Copper Coil vs Aluminium Coil

Three important processes can be associated with AC units, namely; compression, condensation, and evaporation. The refrigerant gas inside the coils needs to be transferred in liquid and gaseous forms. That where the importance of choosing the best coil comes in.

Which one is better; copper or aluminium?

Malleability

The malleability of aluminium is higher than copper. Aluminium can be molded into any shape with ease and comfort. This aspect makes aluminium a highly preferred choice to make AC coils.

Heat exchange

Most advanced inverter split AC models are making use of copper coils or aluminium coils. Copper stands taller in terms of the heat transfer coefficient compared to aluminium. If you want an AC with excellent heat exchange, you can choose one with copper coil

Maintenance

The location of the condenser coil in an AC unit is in the external units. This aspect makes them vulnerable to quirks of weather. Maintenance becomes easy as far as copper coils are concerned. When it comes to aluminium coils, they need to be kept in heavy-duty cabinets.

Price

The aluminium coils are more affordable than copper. That is exactly why air conditioning systems with aluminum coils come at a cheaper price. Therefore, AC units with aluminium coils are cheaper.

Corrosion

Since an AC operates in a damp environment, corrosion becomes a serious concern. It creates a layer over the coil to disturb the conductivity. Leading manufacturers make use of Blue Fin Condenser Technology to protect the coil efficiently. It is the process of paining coils using anti-corrosive materials. Some AC models come with aluminium micro-channel condenser to prevent galvanic corrosion.

Air Conditioning Refrigerant

A refrigerant, also known as the coolant, is an integral part of an AC. The primary function of a refrigerant is to absorb heat from the room and sends it outside. When the heat is eliminated, the air in the room cools down.

How do refrigerants operate?

The coolant or refrigerant is in the form of a gas. The compression process performed by the compressor turns the gas into a liquid. This process is done at very high-pressure levels. When the pressure levels are high, the temperature of the liquid also increases considerably. As the liquid goes through the condenser coils, the liquid temperature is reduced. However, the pressure stays at high levels. For lowering the pressure, the high-pressure cold liquid is released through an expansion valve.

Once it is done, the liquid is transferred through the evaporator coils. The heat available in the room is absorbed by cold liquid before sending it outside. This situation cools down the air in the room. The temperature level is maintained by the fans in the AC unit.

After absorbing the heat, the evaporation of the liquid takes place to change to gas form. When an air conditioning system works, this process is repeated many times.

Different types of refrigerants

You can come across different types of refrigerants including Chlorofluorocarbons (CFC), Hydrochlorofluorocarbons (HCFC), Hydrofluorocarbons (HFC), and Hydrocarbons (HC).

The CFC refrigerants, also known as R12 refrigerants, were used in the air conditioners during the beginning phase of the AC revolution. Since they were causing ozone layer depletion in the atmosphere, manufacturers began to look for better alternatives. That is when HCFC coolants were launched.

Although the CFCs (R12 coolants) were replaced by the HCFCs(R22 coolants), the environmental issues were not addressed properly. This led to the emergence of HFC coolants. Compared to the previous two versions, these refrigerants protect the environment in a much better way. The HFCs are available in three different types; R410A, R32, and R134. Most of the inverter split air conditioning systems available today in India make use of R32 refrigerants.

Hydrocarbons (HC) are the most advanced ones available today. This highly eco-friendly version, also known as a green refrigerant, is slowly gaining in popularity in India

 

When it comes to choosing one of the Best air conditioners in India, you have to look at the tonnage, size, star rating, capacity, room position in the building, and frequency of use. You also have to be mindful of some technical aspects including compressor coil and refrigerant before making a buying decision. First of all, you should know your needs. When you are clear about your needs and the budget available, you can make an informed decision. Various manufacturers offer different types of products nowadays. You must consider the credibility and reputation of the manufacturer. Top companies offer excellent warranty packages to safeguard the interests of the customers.
