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:

  1. pip install erp-air
  2. pull the docker image from project registry
