How does a refrigerated air system work?
A refrigerated air system, also known as air conditioning, works by removing heat and moisture from the air inside a building and transferring it outside, thus creating a cooler and more comfortable environment. The process involves several important components working together in a complex system.
- The evaporator is located inside the building and contains a refrigerant that absorbs heat from the indoor air.
- The compressor pumps the refrigerant from the evaporator to the condenser unit located outside the building.
- The condenser unit releases the hot air from the refrigerant to the outside air, and the refrigerant cools down and returns to the evaporator to repeat the process.
The refrigerant in an air conditioning system is what makes the cooling possible. It is a chemical substance that can easily change from a gas to a liquid and back again. As it evaporates inside the evaporator unit, it absorbs heat from the air inside the building. The gas refrigerant is then pumped outside to the condenser unit, where the hot air is released and the refrigerant is converted back to a liquid. In this condensed form, the refrigerant moves back inside the building to the evaporator and the cooling process continues.
While the above process is happening, excess moisture from the indoor air is also removed and drained away from the building. This is done through a drain pan and a drainage system or pipe that leads to the outdoors.
Types of Refrigerants Used in Air Conditioning Units
Refrigerants are the lifeblood of any air conditioning unit. Without these substances, air conditioners wouldn’t be able to cool your home or office. In simple terms, refrigerants absorb heat from the inside of your home and release it outside, leaving the air inside your space cooler than before.
- R-22: Also known as Freon, R-22 was the most common refrigerant used in air conditioning units for decades. However, due to its harmful effects on the environment, it’s now being phased out. Since January 1, 2020, it’s even been illegal to manufacture or import R-22 in the United States, and by 2030, it will be completely phased out.
- R-410A: Currently, most air conditioning units use R-410A. Unlike R-22, it’s an environmentally-friendly and energy-efficient refrigerant. Among its many benefits, R-410A absorbs heat faster and uses less energy than R-22, making it more energy-efficient and cost-effective in the long run.
- R-32: R-32 is a newer type of refrigerant that’s even more efficient and eco-friendly than R-410A. It doesn’t harm the earth’s ozone layer and has a lower global warming potential (GWP) than R-410A. R-32 has also been found to be slightly more energy efficient than R-410A, meaning it uses even less energy to cool your home or office.
With environmentally harmful refrigerants like R-22 being phased out, it’s more important than ever to make sure you choose an air conditioning unit that uses eco-friendly refrigerants like R-410A and R-32.
It’s also worth noting that the type of refrigerant used in your air conditioning unit can impact its energy efficiency. Energy-efficient refrigerants like R-410A and R-32 can save you money on your energy bills in the long run. So, if you’re in the market for a new air conditioning unit, consider going for a model that uses these eco-friendly refrigerants.
