Split AC

Nowadays, Split ACs are one of the most popular types of AC used in modern homes.

A Split AC contains an outdoor unit & an indoor unit. The outdoor unit includes a compressor, condenser coil, and the expansion coil or capillary tubing. The sleek-looking indoor unit of split AC holds the cooling coil, a long blower with an air filter.

It is a perfect choice if you are looking for a silent working AC for cooling a more extensive area & if the living room’s looks matter much for you. All the noisy components are located in the outside unit of these ACs, making it a perfect AC type to use in a modern home.

Split AC

The split AC is also the most cost-efficient in the long run when compared to other types. No doubt, it uses the most efficient and advanced technology available for domestic usage. If initial cost is not the single deciding factor that matters to you, you should surely go for it.

Pros and Cons of Split AC

Why you should buy ?

  • Looks good
  • Can cool larger rooms.
  • More features
  • Less Noisy

Why you shouldn’t ?

  • Higher installation costs
  • Complicated installation

Buy if : You want a piece of modern equipment to cool larger sized rooms

cyborg wisdomCyborg says:

Among currently available air conditioning technologies, split AC is the most popular choice. It is a one-time investment & with proper, timely maintenance, it is the best value for money compared to other types of ACs.

In the long run, split AC is cost-efficient & is also compatible with all room types. But if the room size is too small and the budget is even lower, you should go for portable AC because it can be used in multiple rooms and have low power consumption because of its lower capacity.

If you are tighter on budget and are sure that you will need AC in a single room only, you might consider window AC over split AC

Types of AC compressor technology

AC compressor

There are basically two types of compressors.

The Reciprocating (piston) air compressor is the one which we use in small ACs made for homes. In contrast, a Rotary air compressor is used in larger sized ACs for heavy commercial usage.

Fixed speed AC

Fixed speed AC is the oldest AC type, which consists of a compressor motor with fixed speed. This type of compressor can only be turned on & off (i.e., no speed regulation). Here, the consumption of power is relatively higher than an inverter AC.

Inverter AC

An inverter type air-conditioner adjusts the compressor’s speed to control the refrigerant flow rate, thereby consuming less current and power.

IntelliSense Inverter Technology in split AC

It is a technology used by Whirlpool to control its compressor with the help of sensors. It optimizes the efficiency based on the temperature set by the user and other ambient conditions. This technology also provides additional benefits such as low noise and stabilizer-free operation (150-264V**), which is a significant plus point.

EXPANDABLE INVERTER Technology in split AC

It is a technology used by Hitachi for extreme weather conditions in tropical regions with high humidity. It enables ACs to boost their capacity for a certain period for consistent & fast cooling.

Dual inverter AC

A dual inverter is a technology used in ACs to optimize power consumption and save energy. In this technology, the AC unit has a variable speed dual rotary motor with a wide rotational frequency that helps different compressor speeds. This adjustment in compressor speed leads to power saving.

Triple inverter AC

An Advanced Digital Inverter 8-Pole Motor powers the triple Inverter Technology. It ensures more energy efficiency and even lesser electricity consumption as there will be lesser torque fluctuations, 

Triple inverters ACs are also capable of converting or changing their capacity according to the user’s requirements.

cyborg wisdomCyborg fact:

The torque generated in the motor to run the compressor of ACs is the main factor responsible for power consumption. Higher the torque required to run the compressor, the more units of electricity it will consume.

cyborg wisdomCyborg suggests:

Triple inverter technology can handle power with fewer fluctuations, resulting in a more power-efficient way for the AC to operate for more extended hours. This type of AC is best for long runs as it provides better efficiency than other ACs technologies available in the market.

Inverter AC technology has a single rotary motor and has a different approach to increase its efficiency. You may consider buying an inverter AC if you can’t afford a triple inverter AC but want the same additional features in a comparatively lower price range. You can also prefer an inverter AC over a triple inverter AC if you aren’t going to use it for long hours, and electricity consumption is not a big concern for you.

Suppose running time for your AC is low, or you use it occasionally. In that case, inverter technology is best suitable for you as it is budget-friendly & also consumes less power if used for shorter durations.

AC Condenser coil and its types

AC Condenser coil

The Condenser coil is responsible for the heat dispersal from the heated refrigerant coming from the compressor. The condenser lowers its temperature, and the refrigerant then goes to the evaporator for further absorption of heat.

Aluminum condenser coil

This coil may be a cheaper option, but it does have many disadvantages. It can’t be repaired and has a lower heat exchange rate, i.e., more power is required for cooling.

Copper condenser coil 

It can be a better option for getting high performance & high efficiency, as it has relatively higher heat exchange rates. These coils are repairable and have high resistance than aluminum coils. 

Alloy condenser coil

These coils are aluminum-based alloys, so we can say that they are a better version of an aluminum coil with some improved quality and performance.

But even then, as far as performance is concerned, copper coils are a better option.

Deciding parameters in the AC Buying Guide to check before buying

AC Buying Guide Parameter #1- Refrigerant types used in ACs

Generally, you can find two types of AC refrigerants nowadays:

R32 AC Refrigerant

It is the most latest & commonly used refrigerant. As compared to all other refrigerants, it increases the efficiency of ACs by around 10%. This gas quality and development is generally focused on its effect on ozone and global warming potential (GWP). So, In the current scenarios, it is the best refrigerant to use.

R410A AC Refrigerant

R410A is one other type of commonly used refrigerants. But as compared to R32, it is considered as the second option. Although its effect on ozone is zero, global warming potential (GWP) is a concern in this type of refrigerant. Also, the efficiency of this refrigerant is lower than R 32.

AC Buying Guide Parameter 2-  Right Selection of AC capacity

For tonnage calculation of ACs

First, you need to find out your room area in sqft (Area= length X breadth).

Then divide it by 600 to get the basic capacity. If your room is 100 sq. feet, the primary AC capacity required will be 0.167 tons (100/600). You need to add 0.5 tons to the basic capacity for every five people in the room. Ordinarily, an AC of 0.8-ton capacity will work just fine for a 100 sq. ft. space.

It gives you a basic idea for choosing the right capacity, But it cannot provide an exact value as few more factors can affect the required tonnage.

AC Buying Guide Parameter 3- “Star-rating of AC”

Star rating & BTU details

The star rating system is used for the consumer’s convenience to give them an idea about its efficiency. It’s common to understand that the higher the star rating, the lower the power consumption. But in actual practice, it also depends on many other different parameters. In simpler terms, it is about how much better or efficiently an AC can use energy concerning some baseline criteria. For example, various ACs with the same specifications and capacity but with different technologies will have separate star ratings as of their energy efficiency.

Star-rating of AC

cyborg wisdomCyborg fact:

BTU stands for British Thermal Units, is a means of measuring heat and energy. One BTU is equivalent to the amount of energy required to heat one pound of water by 1 degree Fahrenheit.

Multiply the BTUs per hour by the number of hours the device run to determine its total BTU output.

AC Buying Guide Parameter 4- “Additional latest features available in split AC.”

Dehumidification in AC

Dehumidification helps the AC to control the humidity level in the indoor environment. It is a necessary part as high humidity or parched weather directly affects a person’s health. It also improves the comfort level. Dehumidification means lower energy costs because it helps your air conditioner run more efficiently.

AC Dust filter

A dust filter improves the quality of air. Its most important function is to protect the ACs from dust particles, which may hamper the performance and efficiency. It directly reduces the AC maintenance cost as you only have to clean the dust filter.

AC Dust filter

Anti-bacteria filter in AC

It removes the particulates and harmful irritants from the air and purifies it before recirculating into the room.

Active carbon filter in AC

 Active carbon filter removes the particulates and harmful irritants from the air by absorption technique. It is useful in the area where there is high air pollution.

Wi-Fi connectivity for AC

If Your AC is WI-FI compatible, it allows you to control it even when you are not at home, as long as it remains connected to the internet.

Activity Sensors of AC

These sensors monitor the movements inside the room and optimize the AC for minimum power consumption.

AC App control

A dedicated app might reduce the dependability of traditional remote control and you will get to control your AC’s functions through your smartphone.

AC Self-Clean

A self-clean feature cleans the Dust automatically just by a press of a button. So, no more manual cleaning is required.

AC Self-Clean

AC Buying Guide Parameter 5 – “Noise levels of AC”

 If you are a light sleeper or have an infant at home, you should always consider this parameter while Buying an AC. A noisy AC is going to create disturbances for you in such cases. If this looks like a problem, you always go for a split AC instead of buying a Window AC.

AC Buying Guide Parameter 6 – “Average temperatures in your city”

If you live in a city where the temperatures break new records every summer, you need to consider buying AC with more tonnage. If the ambient temperature is very high outside, then an AC of higher capacity is needed to cool down even smaller sized rooms.

AC Buying Guide Parameter 7 – “Smart Home compatibility”

If you have already upgraded your house to a smart home or plan to do so soon, you would want to only look for smart products. So, always check the compatibility of any new piece of equipment you buy with the one you already have. Smart features like Alexa and google assistant support will help integrate the AC unit with your smart home seamlessly.

AC-Smart-Home-compatibility

cyborg wisdomCyborg fact:

Suppose you are considering star ratings, not just think of it to denote lower power consumption. More stars on AC imply that the current unit is made better than its baseline versions using various advanced mechanisms and technologies. Obviously, the higher the star rating, the better and more pocket-friendly the AC unit will be.

Top 14 Energy conservation Tips for AC to lower down your electricity bills this summer

  1. Set temperatures at 24°C – Each degree above 75°F/24°C that you set your air conditioner’s thermostat saves you 3 percent of the energy used to cool your home.
  2. Service your air conditioner – Easy maintenance such as routinely replacing or cleaning air filters can lower your cooling system’s energy consumption by up to 15 percent. At a minimum, change the filter every three months. A dirty filter slows down airflow and makes your system work harder to keep you more comfortable.
  3. Open windows – Opening windows creates a cross-wise breeze, allowing you to naturally cool your home without switching on air conditioners
  4. Indoor plants – Getting some good indoor plants will not only enhance the look of your interior but also helps in maintaining the humidity level inside the room. Except that, greenery is always soothing to the eyes and makes you more comfortable.
  5. Fit tight – When installing a window unit, make sure it fits tightly so that outside air does not get in.
  6. Cook outside – Cook outside or at least keep the stove near open windows
  7. Limit the use of humidifier – The increased amount of humidity in the room inhibits the ability of our body to cool itself through perspiration.
  8. Using ceiling fans – Use ceiling fans along with AC to cool down the room effectively and more quickly. Cooling your home with ceiling fans will allow you to raise your thermostat four degrees. This can help lower your electricity bills without sacrificing overall comfort.
  9. The right placement – Don’t place lamps or TV sets near your air-conditioning thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
  10. Use Blinds – Install window treatments or coverings such as blinds, shades, and films to slash heat gain when temperatures rise. These devices not only improve the look of your home but also reduce energy costs.
  11. Shady business – An AC unit operating in the shade uses as much as 10% less electricity than the same one working in the sun.
  12. Seal it up -Caulk air leaks in your room for more efficient cooling. Using low-cost caulk to seal cracks and openings in your home keeps warm air out and cash in your wallet.
  13. Bathroom exhaust – Switch on bathroom fans while using it. Bathroom fans suck out heat and humidity from your home, improving comfort.
  14. Getting smarter – Using a smart Ac gives you the ability to control it with your smartphones. And then it becomes implausible that you misuse the power in your hands if you take energy conservation seriously.

So, now as you know How to save money on air conditioning bills, Let’s implement most of what that we have learned in our daily lives to keep the environment healthy & our pockets wealthy. It will be a small initiative towards a greener earth and a better & healthier livelihood.
