iea_method
(eta_e, eta_th)[source]¶ IEA Method (International Energy Association - a method to allocate the fuel input of chp plants to the two output flows: heat and electricity
The allocation factor of the electricity output is calculated as follows:
: Allocation factor of the electricity flow
: Efficiency of the electricity output in the chp plant
: Efficiency of the thermal output in the chp plant
Parameters: - eta_e (numeric) – The efficiency of the electricity production in the chp plant. Mandatory in the following functions: alternative_generation, exergy, iea, efficiency
- eta_th (numeric) – The efficiency of the heat output in the chp plant. Mandatory in the following functions: alternative_generation, exergy, iea, efficiency
Returns: Allocation factor for the electricity flow
Return type: numeric
