Application

Application

Ventilation and extract ventilation of rooms with a depth up to approx. 6 m
2-pipe or 4-pipe heat exchangers enable good comfort levels
Inducing displacement flow
Energy-efficient solution since water is used for heating and cooling
For new buildings, refurbishment projects and revitalisation projects
Vertical installation on the façade system or an external wall
Typical applications include classrooms in schools, playrooms in daycare facilities, meeting rooms and offices with a high air change rate

Special characteristics

Decentralised ventilation unit for high volume flow rates
Motorised shut-off dampers for fresh air and exhaust air, normally closed (NC) in order to prevent uncontrolled airflows
Demand-based ventilation and extract ventilation is possible by means of monitoring the room air quality and with dedicated control equipment
The type of heat recovery unit depends on the unit variant: cross flow plate heat exchanger, cross counter flow plate heat exchanger including bypass damper with electric actuator (open-close or modulating) or rotary heat exchanger
Heat exchanger as 2-pipe or 4-pipe system, with G½" union nuts and flat seals
Meets the hygiene requirements of VDI 6022
Filter class: F7 for fresh air, G3 for extract air
Easy filter change with quick release fasteners, no tools required
Condensate drip tray with or without condensate drain
Compact construction, hence particularly suitable for refurbishment projects
Automatic switching to secondary air mode (only with an air quality sensor) if the room air quality (measured with the integral VOC sensor, for example) is between the previously defined range. The unit always starts in secondary air mode, which is more energy efficient.
Depending on the unit, an enthalpy heat recovery unit may be used

Functional description

Decentralised supply and extract air units for room ventilation and for dissipating cooling loads and heat loads.

An EC centrifugal fan takes in the fresh air which then flows through the motorised shut-off damper and the F7 filter.

Once the fresh air has passed the fan, it flows through the heat exchanger for heat recovery; it is possible to bypass the heat exchanger in order to pect it, or when it is sensible with regard to energy efficiency.

If necessary, the air is heated or cooled by the heat exchanger before it is discharged to the room as a displacement flow.

The extract air first passes a G3 filter, then flows through the heat exchanger, the extract air fan and the motorised shut-off damper before it is discharged to the outside as exhaust air.

If the room air quality is good, the unit can be operated in secondary mode only.
