Page 7 Some other factors to consider during Piping Selection Equivalent Piping LengthEquivalent Piping Length Type of Joint for branchesType of Joint for branches Outdoor capacity factorOutdoor capacity factor Piping length & height factorPiping length & height factor Refrigerant Pipe SpecificationRefrigerant Pipe Specification Unit & Piping Selection

8. Page 8 Equivalent length is the converted length and includes parts such as elbow, which has pressure losses in the pipe. The formula is as follow: Equivalent length = Real length of tubing + No. of elbow × Equivalent length of each elbow + No. of oil trap ×Equivalent length of each oil trap Equivalent Piping Calculation

9. Page 9 Restriction of Piping Length

10. Page 10 Important Factor to Consider Example: Outdoor Model : MDS100BR Pipe Diameter : 28.6 mm Main Pipe : 80m Branch Length: 20m Elbows: 10 units Oil traps: 3 units Equivalent Length = Real length of tubing + No. of elbow × Equivalent length of each elbow + No. of oil trap ×Equivalent length of each oil trap = (80 + 20) + (10 X 0.5) + (3 X 3.7) = 116.1 m

11. Page 11 When the equivalent length is more than 90% of the maximal real length of the main tubing, the gas pipe need to be increase to one size bigger (diameter). After expanded the gas pipe to a larger diameter, the equivalent length need to be recalculate. The formula is as follow: Expanded Equivalent Length = Equivalent length of main piping X 0.5 + equivalent length of the branch Criteria 1 Criteria 2 Important Factor to Consider

12. Page 12 Important Factor to Consider Maximum allow actual length for 10Hp is 125m Calculated Equivalent Length is 116.1m Ratio of Equivalent Length over Maximum allow Actual Length= 92.88% Equivalent length is more than 90% of the maximal real length. Hence the gas Pipe of MDS100BR need to change. Example:

13. Page 13 Refrigerant Copper Pipe Specification : MDS-B Unit & Piping Selection

14. Page 14 Important Factor to Consider Example: Hence the gas Pipe of MDS100BR need to change from 28.6 mm to 39.40 mm After expanded the gas pipe to a larger diameter, the equivalent length need to be recalculate. Expanded Equivalent Length = Equivalent length of main piping X 0.5 + equivalent length of the branch Main Pipe : 80m Branch Length: 20m Elbows: 10 units Oil traps: 3 units Equivalent Length = Real length of tubing + No. of elbow × Equivalent length of each elbow + No. of oil trap ×Equivalent length of each oil trap = (80 + 20) + (10 X 0.5) + (3 X 3.7) = 116.1 m Expanded Equivalent Length = [80 + (10 X 0.5) + (3 X 3.7)] X 0.5 + 20 Expanded Equivalent Length = 68.05 m
