Refrigerant classification and selection requirements

Refrigerants are also called refrigeration working fluids, commonly known as refrigerants in some areas in the south. It is a working substance that continuously circulates in the refrigeration system and realizes refrigeration through its own state changes.

This is the "3 times", "8 steps" and "5 keys" of central air conditioning installation~~

It is not an exaggeration to say that the central air conditioner is installed with 3 points and 7 points for quality. The central air conditioner needs to be properly matched with the interior decoration. In fact, the equipment itself is only a "semi-finished product".

The effect of insufficient refrigerant charge on the chiller

1. If the suction pressure and discharge pressure of the compressor are lower than the normal value, then you need to check to see if it is due to insufficient refrigerant charge.
