R600a Gas For ACs And HVACs

The difference between R134a and R600a refrigerant in refrigerator:

1. R134a (tetrafluoroethane) is not good for refrigeration systems because of its high water solubility. Even if there is a small amount of water, it will produce acid, carbon dioxide or carbon monoxide under the action of lubricating oil, which will cause corrosion to metals. Therefore, R134a requires higher drying and cleaning of the system.

2.R600a (isobutane) is slightly soluble in water and has good compatibility with most metals such as carbon steel, stainless steel, copper and aluminum.

3.R134a has very low toxicity and is non-flammable in the air. The safety category is A1, which is a very safe refrigerant.

4.R600a has a weak irritation and anesthetic effect. It is a flammable gas. It can form a BaoZa mixture when mixed with air. It may burn BaoZa in case of heat and open flames. Violent reaction with oxidant. Its vapor is heavier than air and can spread to a considerable distance at a lower place, and will ignite back when it encounters a fire source.

5.R134 has a certain greenhouse effect. R600a has no greenhouse effect.
