Difference Between Inverter and Non-Inverter Air Conditioner (With Table)

Inverter vs Non-Inverter Air Conditioner

The difference between inverter and non-inverter air conditioner is that an inverter air conditioner can control the speed of its compressor motor. On the other hand, non-inverter motors run at full speed or stop and turn off once the room temperature falls to the desired level.

When one has to choose the best air conditioner for his home or office, he will consider the popular choices of the inverter and non-inverter air conditioner. Everyone wants to get the best efficient, eco-friendly, and budget-friendly air conditioner in order to live in comfort and have clean, quality air to breathe.

Numerous air conditioners are sold every year and an average household spends approximately 10 percent of its utility bill on cooling units only. This brings the question of how to choose the best air conditioning unit. There are quite a few elements that affect one’s decision but one of the most significant parts to consider before purchasing one is how to choose between the two technologies: inverter and non-inverter.

What is an Inverter Air Conditioner?

An inverter is an energy-saving technology that gets rid of unnecessary operation in air conditioners by effectively managing the speed of the motor. Air conditioners sustain the desired temperature by cooling when the room temperature rises above the desired temperature and heating when the room temperature drops below the desired temperature.

An inverter air conditioner has a varying speed compressor motor that changes the refrigerant flow inside the unit to manage its cooling and heating capacity as needed. The speed of the compressor motor is directly proportional to the frequency of the power supply.

It makes use of a variable-frequency sensor to manage the speed of the motor which regulates the refrigerant flow inside the inverter to supply the right amount of heating or cooling as required. This helps to get rid of the start-stop cycles, hence improving the energy efficiency of the air conditioner.

The benefit of Inverter Technology:

Every air conditioner has a maximum peak load. A 1.5 ton Air conditioner is suitable for a particular size of the room and 1 ton for another size.

A normal air conditioner of 1.5ton capacity will run at an optimum power requirement when the compressor is running. It will run continuously but will pull out only that much power that is needed to keep the temperature that is desired.

So, it automatically adjusts its capacity based on the requirement of the room which it is cooling.

Thus, the main benefit of inverter technology is that it draws quite less power and consumes lesser units of electricity as compared to non-inverter technology.

Although the air conditioners with Inverter Technology adjust according to the room temperature requirement, it is very essential to get the right-sized air conditioner installed in the room.

What is a Non-Inverter Air Conditioner?

An air conditioner unit having a constant speed compressor motor is a non-inverter air conditioner. Unlike an inverter air conditioner, the compressor automatically goes on and off instead of running at full speed throughout.

The compressor goes off when it reaches the set temperature and resumes again after the temperature increases. Because of the repeated on-off cycles, the compressor always works at high power which thus creates a lot of noise while running. It often uses more electricity which makes the air conditioner less energy efficient than the inverter ones.

Main Differences Between Inverter and Non-Inverter Air Conditioner

  • The compressor of the inverter air conditioner runs at full speed constantly to maintain the temperature that is required. The non-inverter air conditioner runs on ‘all or none’ based principle i.e it operates at either full power or no power.
  • The inverter technology saves more energy than the non-inverter type because of its effective method of operation. The non-inverter technology uses more electricity because of the constant on and off frequency.
  • The inverter air conditioner uses a variable frequency method to maintain the speed of the motor and the compressor. On the other hand, non-inverter has a constant speed compressor that automatically goes on and off all the time.
  • The inverter technology does not make a noise while running. The non-inverter air conditioners make a lot of noise while functioning.
  • The life span of inverter air conditioners is more as compared to the non-inverter air conditioner.
  • Inverter air conditioners are more expensive as compared to non-inverter air conditioners. The non-inverter air conditioners are less costly than the inverter ones.

 

Conclusion

In conclusion, we can say that the non-inverter air conditioners may be a little less expensive as compared to the inverter air conditioners, but they are less effective and more costly to manage and maintain.

Inverter unit is the newest air conditioning technology that uses inverters to maintain the speed of the compressor hence helping in getting rid of the frequent on-off cycles.

This ultimately increases its effectiveness and increases the lifespan of the inverter AC units. The initial price might be a little higher than the non-inverter units, but the more cost is a balance against energy consumption which makes it the most favored choice of air conditioner units.
