Trane has introduced CXAF, a new range of high efficiency large air-cooled heat pumps within its Sintesis Advantage portfolio. The company says the new units can meet the cooling and heating demands of medium to large sized commercial buildings and deliver best in class efficiency levels.
Airflow Developments says its new Susurro ceiling-mounted heat recovery unit has been designed to provide continuous decentralised ventilation for both office and educational environments.
With an aluminium cross counter flow heat exchanger, the unit recovers up to 90% of otherwise wasted heat. In accordance with the ErP Ecodesign Directive, Susurro features a 100% summer bypass facility to prevent heat recovery from taking place in hot weather - reducing the risk of overheating.
Its capillary tube system at the air outlet ensures that fresh air is supplied into the room near the ceiling. This then mixes with the ambient air before slowly descending into the room, avoiding any uncomfortable draughts for building occupants.
Stiebel Eltron has launched a new ventilation system designed to improve the energy efficiency of apartments, detached houses and small commercial properties, with minimal disruption.
The LWZ maximises energy efficiency by implementing a unique heat exchanger, allowing for up to 90% of the thermal energy in extract air to be recovered and achieving an A rating in the EU ErP energy standards.
