8. Electronic scale for refrigerant charging
•
Because of the high pressure and fast vaporizing speed
of R410A, the refrigerant cannot be held in a liquid
phase inside the charging cylinder when charging is
done using the charging cylinder method, causing
bubbles to form in the measurement scale glass and
making it difficult to see the reading. (Naturally, the
conventional R22 charging cylinder cannot be used
because of the differences in the pressure resistance,
scale gradation, connecting port size, etc.)
•
The electronic scale has been strengthened by using a
structure in which the weight detector for the refrigerant
cylinder is held by four supports. It is also equipped with
two connection ports, one for R22 (7/16 UNF, 20
threads) and one for R410A (1/2 UNF, 20 threads), so
it can also be used for conventional refrigerant charging.
•
There are two types of electronic scales, one for 10-kg
cylinders and one for 20-kg cylinders. (The 10-kg
cylinder is recommended.)
Refrigerant charging is done manually by opening and
closing the valve.
9. Refrigerant cylinders
•
The R410A cylinders are labeled with the refrigerant
name, and the coating color of the cylinder protector is
pink, which is the color stipulated by ARI of the U.S.
•
Cylinders equipped with a siphon tube are available to
allow the cylinder to stand upright for liquid refrigerant
charging.
10. Charging orifice and packing for refrigerant cylinders
•
The charging orifice must match the size of the charging
hose fitting (1/2 UNF, 20 threads).
•
The packing must also be made of an HFC-resistant
material.
