AIR HANDLING UNITS
airfl ow to meet demand and avoiding unnecessary energy consumption. Heat recovery devices must adhere to minimum effi ciency targets set out in the EcoDesign or ErP directive. Recirculation and free cooling where possible will reduce demand on the heating/cooling system, the use of recirculation or bypass dampers and can dramatically reduce the overall energy consumption. EC fans off er high effi ciency and resilience, the use of which help meet specifi c fan power (SFP) targets set out in the non-domestic building services compliance guide (part L). In addition to lower running and maintenance costs, they are also perfectly suited to the integration with building management systems (BMS). Intelligent control strategy and demand modulation help
ensure the ‘system’ is optimised to deliver the best effi ciency, even at part load. This can be achieved by continuously monitoring temperature, humidity and air quality at an AHU or BMS level and applying energy-optimising control strategies such us Variable Air Volume (VAV) or Constant Air Volume (CAV). Minimising installation costs through the use of factory
fi tted packaged controls, mono-block DX systems can be fully wired and pre-piped (interconnecting pipework). The system is delivered on a common base frame with condensers, expansion valves and controls, leaving just ductwork and power supply to be connected on site. Lifecycle considerations are essential. Proper maintenance procedures of AHUs ensure their longevity and prevent the
premature failure of units. Sustainable disposal and recycling practices for end-of-life components contribute to a circular economy, further reducing the environmental impact of HVAC systems. Traditional HVAC systems are often set-up as separate heating and cooling plants, resulting in increased system complexity and high energy intensity. Combining AL-KO Airtech’s AHUs with Trane’s air-sourced heat pumps (ASHPs) provides the optimum combination of effi ciency, decarbonisation and electrifi cation: The environmental benefi ts of combining heat pumps with
AHUs are dramatic when fossil fuel-based heating systems can be replaced with the latest heat recovery and compressor technology. Trane compressors are some of the most effi cient on the market and use refrigerants with the lowest global warming potential (GWP) currently available. One such example would be Trane’s new ‘Leaf’ R290 heat pump unit (GWP 0.02) when compared to many DX systems running R-410A (GWP 2088). AL-KO Airtech leverages the latest technology in EC fans,
fi lter, and heat recovery, providing AHUs which deliver reliable performance and market-leading performances. Combining lower (GWP) refrigerants in our heat pumps, pushing the limits of AHU effi ciency and using green energy for power, we can help drive HVAC emissions down to almost zero and create a more sustainable future.
