What is the target subcooling and subheting for this system?Updated 2 months ago

Superheat (suction line): 3–5 °C — ensures all refrigerant is vapor before reaching the compressor.

Subcooling (liquid line): 5–15 °C — ensures refrigerant is fully condensed for efficient cooling/heating.

Measured at the outdoor unit service valves; small variations between indoor units are normal.
