1. Refrigerant R134a: R134a (tetrafluoroethane) […]
1. Refrigerant R134a:
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.
R134a has very low toxicity and is non-flammable in the air. R134 refrigerant tub The safety category is A1, which is a very safe refrigerant.
2. Refrigerant R600a:
R600a (isobutane) is slightly soluble in water and has good compatibility with most metals such as carbon steel, stainless steel, copper and aluminum.
R600a has weak irritant and anesthetic effects. 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 when it encounters a fire source.
