Save on Energy Bills with a Ductless Mini-Split System

Mini-split systems are ideal for homes and offices in India. They’re also a good approach to cool homes without capacity for ductwork, additions, garages and more. The system—an outdoor unit and a quiet, wall-mounted indoor unit—is frequently referred to as a mini-split heat pump.

However, mini-splits are more energy efficient because they are zoned systems. This means you can change the heating or cooling in individual areas.

When compared to conventional electric heating systems, the EPA found ENERGY STAR®-rated models can cut your heating costs by up to 50 percent. This is since mini-splits transfer heat instead of making it. A mini-split system could also lower your cooling bill by 30 percent, compared to regular air conditioning. The system can save on energy because it uses compressors and fans to calibrate cooling speeds.

Because there are no ducts on split systems, you won’t have the energy loss involved with ducted systems like central air. The cooling capacity of the AC is represented in BTU/hr. The amount of heat coming inside the room is represented in British Thermal Unit (BTU). All the above-mentioned factors contribute to the BTU. The higher the BTU/hr figure, the higher is the capacity of the AC to remove the heat from the room. It reflects on the efficiency of the AC.

If the heat coming inside the room is more than the cooling capacity of the AC, it will result in the AC working for a longer time thereby increasing electricity consumption. This is a clear case of an undersized AC.

On the other hand, an oversized AC can cool the room faster, but is ineffective in removing the humidity. This AC will run in shorter cycles than the optimum figure. This can also result in reducing the efficiency of the AC.

Therefore, choosing the right tonnage is of atmost important. An inverter AC can also be useful under the circumstances as it can adjust to the size and cooling requirements of the room. Now, inverter AC unit are only available in the Split AC mode.

Factors affecting efficiency of AC

Various factors affect the efficiency of an AC. One should be aware of them to make the right choice. Choosing the right tonnage is of utmost importance. The tonnage depends on the amount of heat it can displace. This, in turn depends on the following factors. Room size – Larger the room, the larger is the amount of heat to be displaced. Hence, you require a higher tonnage for the bigger rooms.

Room population – More the number of people in the room, greater is the heat generated. Hence, an AC has to work harder to displace the heat.

Room congestion – A highly congested room requires an AC of higher tonnage because every item in the room gets cooled by the AC unit.

Electrical appliances – Greater the number of electrical appliances, higher is the emission of heat. This results in installing an AC of higher tonnage.

Number of windows – If there are more windows in the room, there will be more flow of heat from the outside. This requires the AC to work harder. Insulating the windows is an important factor.

Position of the room – The wall facing the sun becomes hot. This can increase the cooling load on the AC necessitating the installation of an AC with a higher tonnage.
