R134a refrigerant introduces whether the refrigerant is added liquid or aerated

Is the refrigerant added liquid or gas? I believe that many people don't understand this problem. Today, the staff of r134a refrigerant will give you an introduction. Let us understand it together.

The staff of r134a refrigerant introduces refrigerants that we can divide into three categories: single working fluid refrigerant, non-azeotropic mixture refrigerant, and azeotropic mixture refrigerant. Regardless of whether the single-working-substance refrigerant is gas or liquid, its composition will not change, so gas can be charged when charging refrigerant. Although the composition of azeotropic refrigerants is different, because the boiling points are the same, the components of the gas and liquid are also the same, so it can be charged into the gas state; the non-azeotropic refrigerants have different boiling points, so the actual composition of the liquid refrigerant and the gas refrigerant It is not the same. At this time, if you add a gaseous state, it will inevitably lead to a different composition of the added refrigerant. For example, only a certain gaseous refrigerant is added, so you can only add liquid.

That is to say, non-azeotropic refrigerants must be added liquid, non-azeotropic refrigerants all start with R4, this kind of liquid must be added, common non-azeotropic refrigerants Boiling refrigerants include: R40, R401A, R403B, r404a, R406A, R407A, R407B, R407C, R408A, R409A, R410A, R41A. As for other common refrigerants, such as: R134a, R22, R23, R290, R32, R500, R600a, no matter how to add gas or liquid, it will not affect the composition of the refrigerant, so how easy it is to come.
