R-290 used in central air conditioners, heat pump air conditioners, household air conditioners and other small refrigerator

product description
R-290 refrigerant, alias R290, Chinese name propane, English name propane, chemical formula C3H8. R290 is a hydrocarbon refrigerant - it has no damage to the ozone layer at all, and the greenhouse effect is also very small. It is mainly used to replace R22 and R502 refrigerants in low-temperature refrigeration equipment; because R290 is flammable, it is usually only used for liquid filling. It can be used in few low temperature refrigeration equipment, or as a component of low temperature mixed refrigerant; R290 is compatible with traditional lubricating oil.

typical application
R-290 is mainly used in central air conditioners, heat pump air conditioners, household air conditioners and other small refrigeration equipment.

storage and transportation
R-290 refrigerant cylinders are pressurized containers, and should be kept away from fire, heat sources, and direct sunlight during storage. They are usually stored in a cool, dry and ventilated warehouse; they should be lightly loaded and unloaded during handling to prevent cylinders and valves, etc. Accessories are broken.

Product advantages
All countries have no restrictions on the initial installation of R290 refrigerant on new refrigeration equipment and the use of after-sales maintenance.

Recommendations for the use of lubricants
Regarding the refrigeration oil used with R-290 refrigerant, the recommendations of refrigeration compressor and refrigeration (air-conditioning) equipment manufacturers should be followed, or the refrigerator with the same design requirements should be determined according to the specific conditions of the refrigeration compressor and refrigeration equipment. Lubricating oil, that is, choose the equivalent refrigeration oil.
