Analysis of common problems of R404a refrigerant

I believe that everyone has a certain understanding of r404a refrigerant through the previous introduction, so what problems do you often encounter when using R404a refrigerant? How is it solved? The following editor will introduce to you, let's take a look.

1. Is it necessary to vent when R404a refrigerant is replaced?

R404a is a mixed refrigerant, it must be vacuumed before filling. Otherwise, the mixing ratio will change, the effect will not be achieved, and the equipment will even be damaged.

2. Is r404a refrigerant flammable?

Non-flammable. R404A is a non-azeotropic mixed refrigerant without chlorine. It is a colorless gas at room temperature and pressure. It is a compressed liquefied gas stored in a steel cylinder. Its ODP is 0, so R404A is an environmentally friendly refrigerant that does not destroy the ozone layer of the atmosphere. Main application: R404A is mainly used to replace R22 and R502. It has the characteristics of cleanliness, low toxicity, non-combustibility, and good cooling effect. It is widely used in medium and low temperature refrigeration systems.

3. Does r404a refrigerant contain fluorine?

R404A refrigerant is an environmentally friendly refrigerant, suitable for low-temperature refrigeration.

4. What is the working low pressure of R404 for refrigerator refrigerant?

It is normal that the working low pressure of R404 for refrigerator refrigerant is in the range of 4-6. R404A is a mixture of HFC125, HFC-134a and HFC-143. It is a colorless gas at room temperature and a colorless and transparent liquid under its own pressure. R-404A is suitable for new commercial refrigeration equipment and transportation refrigeration equipment at medium and low temperatures. Or update equipment. Similar to the operation of R-502, it can even reach 15°F (-9.4°C) or colder. This refrigerant is suitable for all environments where R-502 can operate normally.
