HVACR performance measurement to optimize energy consumption


Reduce climate impact

Scientists continually alert us about the climate emergency, whose first cause is an excessive energy consumption and fossil fuels burning.


Reduce energy consumption

Between 15-20% of global electricity consumption is used for refrigeration and air conditioning (HVACR). Depending on the climatic area it can represent up to 50%

Reduce energy costs

Most of HVACR systems don’t work as efficiently as they were designed, which means a higher energy cost and an increasing risk of failure and, in the end, increased CO2 emissions.

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
