What is an air handling unit?
An air handling unit (AHU) is a professional installation designed to provide central ventilation in commercial and utility premises. With this device, temperature and also humidity can be kept at a pleasant level. An air handling unit is the housing for a fan, filter, heating and/or cooling element, heat recovery and other fittings. They can be equipped with heat recovery by means of a heat wheel, crossflow or counterflow exchanger and twincoil.
How does an air handler work?
The operation of a plant system is less complex than it seems. The exchanger in a cross-steam system consists of stainless steel or aluminum plates that are alternately flat and corrugated. Along these plates flow separately the supply and return air. The results depend on temperature and humidity.
Current legislation
The legislation can be quite extensive. What do you need to consider? The current developments in legislation at a glance:
▪ EIA label
▪ Environmental database
▪ ERP legislation
Standards
To help preselect the quality level of your air handling unit, the easy-to-read Eurovent Energy Label is available. There are six labels to choose from, namely: A+, A, B, C, D and E. The labels set groundbreaking requirements and are independently Eurovent-certified. All promised performance is thus fully guaranteed.
Maintenance
For the maintenance of air handling units, specifications have been developed by Platform Binnenklimaattechniek partners. These are practical documents that can be used as a kind of checklist when improving the quality of the overall air conditioning system. The goal is to optimize energy savings and comfort improvements in the building.
Tools
The Life Cycle Cost (LCC) Tool was developed for air handling units. With this tool you can compare different cabinets on energy consumption and CO2 emissions. The input to the calculation takes full account of Dutch energy and gas prices and is also applicable for energy use from other sources.
