  • PT - heating capacity
  • Tp1 - air temperature at the unit inlet
  • Tp2 - air temperature at the unit outlet
  • Tw1 - heating medium temperature at the heat exchanger inlet
  • Tw2 - heating medium temperature at the heat exchanger outlet
  • Qw - heating medium flow rate in heat exchanger
  • Δpw - heating medium pressure drop in heat exchanger

If you want to calculate heating capacity at different parameters you can do this at manufacturer website.
