R-290 refrigerant (refrigerant grade propane) alias R290, Chinese name propane, English name propane, chemical formula C3H8. R290 is a hydrocarbon refrigerant-it does not damage the ozone layer at all, and the greenhouse effect is also very small. It is indeed the most environmentally friendly refrigerant today. From the perspective of environmental protection, almost all countries in the world have used R290 refrigerant in new refrigeration equipment There are no restrictions on the initial installation and after-sales maintenance.
The main purpose of R-290
It is mainly used to replace R22 and R502 refrigerants in low-temperature refrigeration equipment; because R290 is flammable, it is usually only used in low-temperature refrigeration equipment with a small amount of liquid, or as a component of low-temperature mixed refrigerant; R290 and Compatible with traditional lubricants.
R-290 storage and transportation
R-290 refrigerant cylinders are pressurized containers and are flammable and explosive. They should be stored away from fire, heat, and direct exposure to sunlight. They are usually stored in a cool, dry and ventilated warehouse; they should be loaded and unloaded lightly during transportation. , To prevent damage to accessories such as cylinders and valves.
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 molecule, 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.
