With PilotE² method

How it works

PilotE² method calculates refrigeration or heat pump thermodynamic cycles performance based on thermodynamics principles.

PilotE² method is a direct and indirect methods combination, using the best of each. It uses a direct method to determine instantaneous performance but also measures evaporator or condenser energy, when possible, to obtain additional information on final energy use.

PilotE² method use only six measurement points in a simple setup, one power meter, two pressure sensors (high and low compressor pressure) and three temperature sensors).

Reliability and accuracy

PilotE² method is a more reliable and accurate than other methods based on air and water measurements. It allows to calculate this Key Performance Indicators (KPI):

  • Cooling and Heating Power (kW)
  • Coefficient of Performance COP/ EER
  • Global System Efficiency
  • Compressor Isentropic Efficiency
  • Condenser Efficiency
  • Evaporator Efficiency
  • Electrical Energy Consumption
  • Air/Water Flow, Power, Temp. Delta, Energy
  • Superheat/Sub-cooling values
