CERA residential ventilation | NX type Total ventilation concept for stacked housing

CERA residential ventilation | NX type

CERA stands for Central Energy Recovery Air flow and is a total ventilation concept designed for use in stacked housing. The primary system includes a central heat recovery in the central AHU unit and is maintaining duct static
pressures at a minimum. Air balance is carried out by measuring the supply air to the apartments and by controlling the return air accordingly.

About CERA

CERA stands for Central Energy Recovery Air flow and is a total ventilation concept designed for use in stacked housing. The primary system includes a central heat recovery in the central AHU unit and is maintaining duct static pressures at a minimum. Air balance is carried out by measuring the supply  air to the apartments and by controlling the return air accordingly. The energy consumption required for ventilation and ventilation transmission is reduced by 30-50% compared to conventional systems. The result is a very energy conscious system. Optionally the system can be upgraded by providing some cooling capacity through the ventilation air. The unit is compact in size and can be used in new developments, renovations or transition projects.

System operation

The system consists of a ventilation air control unit called the CERA unit, which is installed in each apartment. By measuring the air quality - i.e. the CO2 levels in the room(s) - the amount of fresh air supplied into each room is kept to a minimum. Under normal conditions the air volume is  controlled between a minimum and maximum flow based on local regulations. By adding a switch in the kitchen (during cooking periods) and a switch in the bed/bathroom (during showering) the supplied air volumes will be increased to a higher factory calibrated set-point. During night time the system can be put in night-mode and providing sufficient fresh air into the bedroom.

Sustainable ventilation system

When the primary system uses a heat pump, thermal energy storage system or district heating or cooling system, it is possible to achieve an exceptionally low energy consumption. Depending on the application, the system can contribute to get a higher degree in a green building certificate. Another advantage of this is, when during the conversion of offices into apartments the existing infrastructure of ducts, shafts and technical spaces, can be used.
