What is a Split AC?
A split air conditioning unit, as the name suggests, consists of two parts – the indoor unit and the outdoor unit. The indoor unit is usually installed in the room, and it is responsible for cooling the air, while the outdoor unit houses the compressor and other parts necessary for the cooling process.
How Does a Split AC Work?
The split AC works by using a refrigerant to absorb heat from the air and then transferring it to the outdoor unit, where it is dissipated into the atmosphere. The compressor plays a critical role in this process as it is responsible for compressing the refrigerant, which increases its temperature and pressure. This compressed refrigerant is then sent to the condenser, where it releases its heat and condenses back into a liquid form.
Types of Compressors
There are four types of compressors used in split ACs, namely reciprocating compressor, rotary compressor, scroll compressor, and inverter compressor. Each type of compressor works differently, and their performance varies based on factors like energy efficiency, noise level, and cost.
Reciprocating Compressor
A reciprocating compressor is a type of compressor that works by compressing air using a piston and cylinder. It is a positive displacement compressor, which means that it compresses a fixed amount of air with each stroke of the piston. Reciprocating compressors are commonly used in small-scale applications, such as household refrigerators and air conditioning units.
Advantages of Reciprocating Compressors
One of the main advantages of reciprocating compressors is their high energy efficiency. They can achieve high compression ratios with minimal energy consumption, making them a cost-effective option for air conditioning and refrigeration systems. Reciprocating compressors also have a compact design, making them easy to install in tight spaces.
Disadvantages of Reciprocating Compressors
One of the main disadvantages of reciprocating compressors is their high noise level. They produce a loud, pulsating sound that can be disruptive in quiet environments. Reciprocating compressors are also known to have a shorter lifespan compared to other types of compressors, as the constant motion of the piston can cause wear and tear on the compressor components.
Best Suited for
Reciprocating compressors are best suited for small-scale applications that require high energy efficiency and a compact design. They are commonly used in household refrigerators and air conditioning units, as well as in industrial applications such as gas processing and petrochemical refining. However, they may not be the best option for applications that require low noise levels or high durability.
Rotary Compressor
A rotary compressor is a type of compressor that works by compressing air using rotating impellers or screws. It is a positive displacement compressor, which means that it compresses a fixed amount of air with each rotation of the impellers or screws. Rotary compressors are commonly used in larger-scale applications, such as commercial air conditioning and refrigeration systems.
Advantages of Rotary Compressors
One of the main advantages of rotary compressors is their high durability. They are designed with fewer moving parts than reciprocating compressors, which means they experience less wear and tear over time. Rotary compressors are also known for their quiet operation, producing significantly less noise than reciprocating compressors. They are also more efficient at handling varying loads and maintaining a constant output, making them ideal for applications with fluctuating demand.
Disadvantages of Rotary Compressors
One of the main disadvantages of rotary compressors is their lower efficiency at lower speeds. They require a minimum speed to operate effectively, which means that they may not be the best option for applications with low demand. Rotary compressors also have a larger footprint than reciprocating compressors, which means they may require more space for installation.
Best Suited for
Rotary compressors are best suited for larger-scale applications that require high durability and efficient operation. They are commonly used in commercial air conditioning and refrigeration systems, as well as in industrial applications such as gas compression and chemical processing. However, they may not be the best option for applications with low demand or limited installation space.
Scroll Compressor
A scroll compressor is a type of compressor that works by compressing air using two interleaving scrolls. One scroll is stationary while the other moves in a circular motion, trapping and compressing air between the two scrolls. Scroll compressors are known for their high efficiency and quiet operation, making them a popular choice for air conditioning and refrigeration applications.
Advantages of Scroll Compressors
One of the main advantages of scroll compressors is their high energy efficiency. They are designed with fewer moving parts than other types of compressors, which means they experience less wear and tear over time. Scroll compressors also have a high volumetric efficiency, meaning they can compress a larger volume of air per unit of time than other types of compressors. They are also known for their quiet operation, producing significantly less noise than reciprocating compressors.
Disadvantages of Scroll Compressors
One of the main disadvantages of scroll compressors is their high initial cost. They are more expensive than reciprocating compressors, which can make them less accessible for smaller-scale applications. Scroll compressors are also known to have a lower durability compared to other types of compressors, as the scrolls can wear down over time with constant use.
Best Suited for
Scroll compressors are best suited for air conditioning and refrigeration applications that require high energy efficiency and quiet operation. They are commonly used in residential and commercial air conditioning systems, as well as in refrigeration systems for food storage and transportation. However, they may not be the best option for applications that require high durability or have a limited budget.
Inverter Compressor
An inverter compressor is a type of compressor that works by adjusting the speed of the compressor motor to match the demand of the air conditioning or refrigeration system. This allows the compressor to operate at varying speeds, rather than constantly turning on and off. Inverter compressors are known for their energy efficiency and precise temperature control.
Advantages of Inverter Compressors
One of the main advantages of inverter compressors is their energy efficiency. By adjusting the speed of the compressor motor to match the demand of the system, they can operate at lower speeds when demand is low, resulting in energy savings. Inverter compressors also provide more precise temperature control, as they can adjust the speed of the compressor to match the required cooling or heating output. This results in a more comfortable and consistent indoor environment.
Disadvantages of Inverter Compressors
One of the main disadvantages of inverter compressors is their higher initial cost. They are more expensive than traditional compressors, which can make them less accessible for smaller-scale applications. Inverter compressors are also more complex than traditional compressors, which can make them more difficult to repair if issues arise.

Inverter compressors are best suited for air conditioning and refrigeration applications that require high energy efficiency and precise temperature control. They are commonly used in residential and commercial air conditioning systems, as well as in refrigeration systems for food storage and transportation. Inverter compressors are ideal for applications with fluctuating demand, as they can adjust the speed of the compressor motor to match the demand of the system. However, they may not be the best option for applications with a limited budget or for those who prioritize simplicity over advanced technology.
