High-purity R290 is used as a temperature-sensing working fluid; premium and first-grade R290 can be used as a refrigerant to replace R22, R502, compatible with the original system and lubricating oil, and used for central air conditioning, heat pump air conditioning, household air conditioning and other small refrigeration equipment , Can also be used for metal oxygen cutting gas.


     R290: A potential refrigerant substitute


     The refrigerant R290, or propane, is a natural hydrocarbon refrigerant that can be obtained directly from liquefied petroleum gas. Compared with Freon, a synthetic refrigerant, the natural working fluid R290 does not contain chlorine atoms in its molecules, so the ODP value is zero, which does not have a destructive effect on the ozone layer. In addition, compared with HFC substances that also have no destructive effect on the ozone layer, the GWP value of R290 is close to 0, which has no effect on the greenhouse effect.


1) R290 storage


R290 refrigerant cylinders are pressurized containers. They should be stored away from fire, heat, and direct sunlight. They are usually stored in a cool, dry and ventilated warehouse;


R290 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) R290 transportation


When using steel cylinders, you must wear the safety helmets on the cylinders. Place the steel cylinders horizontally, with the mouth of the cylinder facing the same direction, and do not store them 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 keep 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.;
