Note1. If the A/C system is designed to use cooling mode under outdoor temperature 10°C, H’<=15m.
Note2. As bents cause pressure loss on transportation of refrigerant, fewer bents design is better;
Piping length needs to consider the actual length and equivalent length which bents are counted.
Equivalent piping length (m)=Actual piping "M" x Quantity of bent.
