R32 refrigerant

What is R32?

Difluoromethane is a halogenated hydrocarbon (chemical formula: CH2F2), abbreviated as R32. It is a gas at room temperature, and is a colorless and transparent liquid under its own pressure. It is easily soluble in oil and insoluble in water. It is a coolant with zero ozone loss potential.

R32 use

Difluoromethane and pentafluoroethane form an azeotrope (known as R-410A) that is used as a replacement for chlorofluorocarbons (also known as Freon) in new coolant systems, primarily as a replacement for HCFC-22 , as a compound medium and low temperature mixed refrigerant. Although it has zero ozone depletion potential, it has a high global warming potential that is 550 times that of carbon dioxide on a per 100-year basis.

Note on storage and transportation of R32 refrigerant

(1) R32 storage

• The R502 refrigerant cylinder is a pressurized container. It should be stored away from fire, heat sources and direct sunlight. It is usually stored in a cool, dry and ventilated warehouse;
• R502 is stored separately from oxidants, inflammables or combustibles, and aluminum, and remember to store them together.
• The storage area should be equipped with leakage emergency treatment equipment
• Pay attention to the name of the product and the date of acceptance when accepting, and the advanced warehouse will be used first;

(2) R32 transportation

• When transporting in cylinders, the safety cap on the cylinder must be worn. The cylinders are placed horizontally, and the mouths of the cylinders are in the same direction, and do not store them crosswise;
• When handling, it should be lightly loaded and unloaded 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 slip away during railway and road transportation;
• It is strictly forbidden to mix with oxidants, flammable or combustible materials, active metals, etc.
