What are the application and precautions of r404a refrigerant?

At present, due to the continuous application of environmentally friendly refrigerants and the continuous updating of various types of refrigerants, r404a refrigerant is a widely used model among environmentally friendly refrigerants. r404a refrigerant is a colorless gas at room temperature, and a colorless transparent liquid under its own pressure. This refrigerant is suitable for all normal operating environments, and is closest to R-502, so the application and precautions for r404a refrigerant I don't know how much everyone knows, so the editor will take you to introduce some related content about r404a refrigerant in detail.

1. R404a brand

, Dongyue, Chemours, Honeywell, Jin Leng, Sanmei and other brands.

2. R404 refrigerant packaging

Non-reusable steel cylinder 10.9KG.

Reuse steel cylinder 400L/800L/926L/1000L.

Tank truck 18T.

3. R404A storage and transportation

The refrigerant R404A cylinder is a pressurized container. It should be stored away from fire, heat, and direct sunlight. Usually Store in a cool, dry and ventilated warehouse; load and unload with care during transportation to prevent damage to steel cylinders, valves and other accessories.

4. R404A supporting refrigerating machine oil

The refrigerating machine oil usually used with refrigerant R404A are: ICEMATIC SW32, SW220, EMKARATE RL32H, RL170H, etc. ; What kind of refrigerating oil is finally used in different equipment and different application places should follow the recommendations of the refrigeration compressor and refrigeration (air-conditioning) equipment manufacturers, or determine the use of the same design and technicians according to the specific conditions of the refrigeration compressor and refrigeration equipment. The required refrigerator lubricating oil is the equivalent refrigerator oil.

5. Uses

The refrigerant R404A is the most common industry standard refrigerant to replace Freon R22 and R502 in newly installed refrigeration equipment (usually low temperature refrigeration System), R404A is the closest to the operation of R-502. It is suitable for all environments where R-502 can operate normally. R404A is recognized and used by most refrigeration equipment manufacturers in the world. However, because R404A and R502 and R22 have different physical and chemical properties, theoretical cycle performance and compressor oil, etc., for the after-sales maintenance of refrigeration equipment initially installed as R502 and R22 refrigerants, if you need to add or replace refrigerants, you still need to add or replace refrigerants. Only R502 and R22 can be added, usually R404A cannot be used to replace R502 and R22 directly (that is, exchange-type replacement is usually not possible).

are an important part of the society and they come in handy in any place where there are start capacitor suppliers in need of start capacitor suppliers.
