R600a Nevada Compared to R134a Nevada in Refrigerators
Due to its high water solubility, R134a (tetrafluoroethane) is not good for refrigeration systems. Even if there is a small amount of water, under the action of lubricating oil, it will produce acid, carbon dioxide or carbon monoxide, which will corrode metals. Therefore, R134a requires higher drying and cleaning of the system. R600a (isobutane) is slightly soluble in water and has good compatibility with most metals such as carbon steel, stainless steel, copper and aluminum.
R134a has very low toxicity, is non-flammable in the air, and has a safety category of A1, which is a very safe refrigerant.
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. It reacts violently on contact with oxidants. 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. R134 has a certain greenhouse effect. R600a has no greenhouse effect.
R600a's evaporating pressure, condensing pressure, and exhaust temperature are lower than R-134a. The lower liquid density of R600a refrigerant makes its charging capacity 45% of R-134a's. It has good refrigeration performance, and its refrigeration capacity is 55 of R-134a. %; R600a refrigerant has a strong destructive effect on the ozone layer due to R11 and R12, and the greenhouse effect is obvious. Among the CFCS alternative routes, one is the alternative route using R134a refrigerant represented by the United States and Japan; the other is It is represented by Germany as an alternative route using hydrocarbons as refrigerants.
(1) R600a storage
R600a refrigerant cylinders are pressurized containers. They should be stored away from fire, heat sources, and direct sunlight. They are usually stored in a cool, dry and ventilated warehouse;
R600a is stored separately from oxidizers, combustibles or combustibles, and aluminum. Remember to store them together.
Storage area should be equipped with leakage emergency treatment equipment.
Pay attention to the product name and the date of acceptance during acceptance, and use advanced warehouses first;
(2) R600a transportation
When using steel cylinders, you must wear the safety helmets on the cylinders. Place the steel cylinder horizontally with the mouth of the cylinder facing the same direction and do not store it crosswise
When transporting, load and unload lightly to prevent damage to accessories such as cylinders and valves.
In summer, it should be transported in the morning and evening to prevent sun exposure and away from heat sources;
It is forbidden to drop off during railway and road transportation;
Do not mix with oxidants, combustibles or combustibles, active metals, etc.;
The advantages of typical hydrocarbon refrigerants such as isobutane (R600a) just overcome the shortcomings of R134a refrigerant.
The excellent thermophysical properties of R600a determine that the refrigerant has higher energy efficiency and compressor efficiency
than CFCS and HFCS. (COP value) and the refrigerator's overall cooling efficiency (power consumption index) are higher than R134a.
Due to the advantages of energy saving and environmental pollution, Germany first succeeded in using hydrocarbons as refrigerants in
refrigerators. With the maturity of process and technology, R600a refrigerant has also been widely used in China's refrigeration industry.
