emissionSystem.py

Model of different Emission systems using a builder pattern. New Emission Systems can be introduced by adding new classes

my_emission_director = emissionSystem.EmissionDirector()

Initialises an emission systems manager

my_emission_director.setBuilder(my_emission_system(energy_demand))

Set the Emission System type, with the energy demand of that space. my_emission_system can be replaced by any of the classes listed in the Builder Options section below

Input

• energy_demand: The space energy demand of the building in Watts

Return

• phi_ia_plus: The added heat flow to the air node
• phi_st_plus: The added heat flow to the surface node
• phi_m_plus: The added heat flow to the thermal mass node
• heatingSupplyTemperature:
• heatingReturnTemperature:
• coolingSupplyTemperature:
• coolingReturnTemperature:
