• Heat Pump System (2 Pipes)
• Heat Recovery System (3 Pipes)
Correction Factor for Heating Capacity According to Piping Length
The heating capacity should be corrected according to the following formula:
HCA=HC x F
HCA: Actual Corrected Heating Capacity
HC: Heating Capacity in the Performance Table
F: Correction Factor Based on the Equivalent Piping Length
