CRAC units for Data Centres

1 post / 0 new

Hello everybody.

Does anyone know how to model a room that uses CRAC units? CRAC units is
equipment located within the zone. They have cooling coils, electrical
heating batteries, and variable speed fans. They actually circulate the
room air and a very small amount of air (compared to the CRACs airflow)
is coming from a central AHU for the fresh air requirements of the
space. This AHU may as well provide fresh air to other spaces too and
has heat recovery.

Could you please tell me which will be the correct systems to model the
described function?

Thank you in advance,
