3.1 CAPACITY TABLES

3.1.1 Nominal capacity-performance tables

3.1.1.1 Considerations

• The heating capacity tables show the capacity and performance data in integrated values (with defrost correction factor
included).
• The nominal heating and cooling capacities are based on the EN 14511 standard: Piping length: 7.5 meters; Piping lift: 0 meters.
Keywords:
• CAP: Nominal capacity (kW)
• COP: Coefficient of performance
• EER: Energy efficiency ratio
• DB: Dry bulb; WB: Wet bulb (ºC)
• OAT: Outdoor ambient temperature (ºC)
• WIT: Water inlet temperature (ºC)
• WOT: Water outlet temperature (ºC)
