As for the air conditioners, most people will notice the airflow, then the temperature and the remote control. Hardly had someone mention the core part—the compressor. It is not seen directly like a shell, but like the heart of a human, striving to make the whole system work.

Now let's go deep into the air conditioners and get to know this silently beating heart.

 

What is the compressor?

 

The function of the compressor is to compress the low-pressure gas (refrigerant) into high-pressure gas and push it to circulate in the air conditioning system, achieving cooling/heating exchange.

Simply, the duty of the compressor is to pump and supply the cold air or drive to heat. The air conditioner cannot work without the compressor.

 

How does the compressor work in the air conditioner?

 

A whole air conditioning circulation consists of four core parts: the condenser, the compressor, the evaporator, and the expansion valve. In which the compressor is in the middle of the circulation.

 

 

Why does it say the compressor is the heart of the air conditioner?

 

Continuous operation: Once the compressor works, it normally keeps working for a long time, like our heart, to maintain motivation continuously.

Energy efficiency ratio: The better the performance of the compressor, the better the energy-saving effect of the air conditioner.

Lifespan: The compressor determines largely whether the air conditioner is good or not.

Cooling/heating speed: If the compressor is powerful, then the air conditioner will cool and heat quickly and stably.

 

Types of the compressors for air conditioning

 

Model	Specifications	suitable machines
Rotary compressor	Compact structure, high efficiency, moderate price	Household wall mounted air conditioners and cabinet units
Piston compressor	Low initial cost, but high noise, low efficiency	Early models, now less used
Scroll compressor	Stable operation, low noise, high energy efficiency	Mid- to high-end commercial air conditioners

 

How to choose an air conditioner with a good compressor?

 

When choosing air conditioners, it is possible to check the following:

 

Compressor brands, such as GMCC, MITSUBISHI, HITACHI, PANASONIC, etc.;

Adopt inverter technology, which will be more energy-saving;

With an energy efficiency certificate, trusted quality with high efficiency and stability;

Longer warranty period from the manufacturer and reliable quality.

 

Take our KRG as an example. Many of our models use compressors from well-known brands and have passed CE, SASO, and other certifications to ensure stable and efficient operation of the air conditioning system.

 

 

The compressor is not very visible, but it holds the core of the air conditioner's performance. It determines whether the cooling and heating are fast and stable and also directly affects the power consumption and machine life. As a consumer, understanding the operating principle and importance of the compressor can make you buy with more confidence and use with more peace of mind!
