Find out the types of gas on the air conditioner
Gas R22 is the first gas used on air conditioners, with the advantage of being easy to maintain when you want to pump more gas, non-toxic, non-flammable as well as relatively cheap, so this gas is quite popular.
However, this is a gas that can harm the ozone layer, so according to the development roadmap, this gas will only be used until 2040. Besides, although it is not toxic, it will cause suffocation if the gas concentration is high. in the air is too high.
2. Gas R410A
According to the Kyoto decree signed in December 1997, developed countries must reduce the greenhouse effect to protect the environment, so the R410A gas was invented to replace the R22 gas.
Gas R410A has the same chemical composition as R22, but has a higher volatility, and when the environment is low, it will cause oxygen deficiency, so your room must be well ventilated otherwise it will be very dangerous. danger of gas leakage. The reason that R410A gas is a perfect replacement for the old R22 gas is for the following reasons:
The cooling capacity is 1.6 times higher than that of R22 gas.
Compared to the type using gas R22, the air conditioner uses R410A gas for a deeper cold, saving more electricity.
The type of gas R410A contributes to environmental protection because it does not cause ozone depletion.
However, the type of gas R410A also has some “cocoon” disadvantages for users such as:
- The machine uses gas type R410A which is difficult to maintain, injecting more gas than R22 (when adding R410A gas, it is necessary to completely withdraw the remaining gas in the tank – while for R22 gas, it can be pumped more without withdrawing. old gas out).
Air conditioners using R410A gas have a higher cost than R22 air conditioners and at the same time, the cost of gas refilling and new gas pumps is often very high and when pumping gas, a variety of specialized equipment must be used.
3. Gas R32
Gas type R32 is the latest gas type today, the most used application in Japan. This gas was invented to replace gas R22 and type R410A. About this new type of R32 gas, it has outstanding advantages that can be mentioned as follows:
Gas R32 achieves GWP (550) emission standards many times lower than R410A (1980) gas, reducing emissions by up to 75%, meeting environmental protection requirements, resisting heat rise. leading to the greenhouse effect.
Power saving: With much greater cooling efficiency than R410A gas, R22 should use R32 gas air conditioners, which will save outstanding energy due to fast and powerful cooling time.
Easy to adapt: Although the formula is different, but R32 gas with a pressure equivalent to R410A gas is very popular, so it can be used with installed equipment, just need to change the gas charging meter and gas charging wire.
