Evaluate Air Handling Unit per Ecodesign.
Project description
INTRO
Starting from 2018 all ventialtion units should comply with the requirements of the COMMISSION REGULATION (EU) No 1253/2014 of 7 July 2014 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for ventilation units.
This package solves only non-residential ventilation units.
These requirements sometimes being refered as ErP
or
Ecodesign
.
It is importnat to introduce some notations in order to understand the code better:
nrvu - non-residential ventialtion unit
sfp - specific fan power
int - internal (do not confuse with integer:))
ext - external
hrs - heat recover system, i.e. rotory wheel, plate heat exchanger o run-around-coil
rac - run-around coil heat recovery
rw - rotory wheel heat recovery
phex - plate heat exchnager heat recovery
uvu - unidirectional ventialtion unit
bvu - bidirectional ventialtion unit
eff - efficiency
sup - suply side of the air handling unit
eta - extract side of the air handling unit
More expanded list of notation can be found in the Article 2 and Annex I.2 of the regulation
INSTALATION
There are two ways:
- pip install erp-air
- pull the docker image from project registry
