Rotary compressors are compact, efficient, and quiet, making them a popular choice for inverter ACs. These compressors work by using rotating vanes to compress the refrigerant, resulting in smooth and continuous cooling.

Scroll Compressor

Scroll compressors are another option for inverter ACs. They work by using two spiral-shaped scrolls to compress the refrigerant, providing efficient and quiet operation. Some folks even say they’re more durable than rotary compressors, but it’s up to you to decide which one is the better fit for your needs. Both types have their advantages and can deliver excellent performance in an inverter AC system.

Inverter Controller

The brain behind the operation, the inverter controller, is responsible for managing the compressor’s speed. There are two main types of controllers: Pulse Width Modulation (PWM) and Vector Control.

Pulse Width Modulation (PWM)

PWM controllers work by sending a series of electrical pulses to the compressor, adjusting its speed as needed to maintain the desired temperature. They’re known for their efficiency, precision, and reliability, making them a solid choice for inverter AC systems.

Vector Control

Vector control is another option for inverter controllers. It’s a more advanced technology that offers even better efficiency and precise control than PWM. If you’re looking for the best of the best, vector control might be the way to go.

Inverter AC Outdoor Unit

Now let’s move on to the outdoor unit, which houses some essential components of your inverter AC system.

Heat Exchanger

The heat exchanger plays a crucial role in cooling your home by transferring heat from the indoor air to the outdoor air. It’s made of a series of coils that allow refrigerant to flow through, absorbing and releasing heat as needed.

Expansion Valve

The expansion valve is another vital component, responsible for regulating the flow of refrigerant into the heat exchanger. This helps maintain the right balance of pressure and temperature, ensuring efficient cooling.

Inverter AC Indoor Unit

Now let’s take a look at the indoor unit, which is responsible for blowing that sweet, cool air into your home.


The evaporator is the part of the system that actually cools the air. It’s a series of coils filled with refrigerant, which absorbs heat from the air passing over them. This process lowers the temperature of the air, providing the cooling effect we all know and love.

Air Filter

Before the air reaches the evaporator, it passes through an air filter that removes dust, pollen, and other particles. This not only improves your indoor air quality but also helps maintain the efficiency of your inverter AC system.

Fan and Blower

Once the air has been cooled by the evaporator, a fan, and blower push it back into your home, providing that refreshing blast of cool air. These components are designed to work quietly and efficiently, ensuring you stay comfortable without a lot of noise.
