This way, the airflow is increased during busy periods and reduced the rest of the time.<\/p>\n\n\n\n<p>Air handling units ensure the air exchange and heating\/cooling of the commercial premises. The AHUs operate at a fixed flow rate over time slots programmed according to opening hours.&nbsp;<\/p>\n\n\n\n<p>By installing this technology, which has been available on the market for more than 5 years, the company can achieve significant savings on its electricity bills and reduce its carbon footprint. This measure is relatively simple to implement, has a quick return on investment and does not require production shutdown during the technical installation.<\/p>\n\n\n\n<!--more-->\n\n\n\n<p><\/p>\n\n\n\n<h3 class=\"type-numerotation\"><span class=\"type-numerotation-span visually-hidden\"><\/span>Energy and environmental impact<\/h3>\n\n\n\n<p>Adjusting the supply of fresh air according to occupancy has the effect of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>reducing the heat consumption needed to heat the outside air in winter<\/li>\n\n\n\n<li>reducing the refrigerant consumption to cool the outside air in summer<\/li>\n\n\n\n<li>lowering the power consumption of air supply and return fans<\/li>\n<\/ul>\n\n\n\n<p>The use of CO<sub>2<\/sub> sensors with dampers and controls to adjust the flow of fresh air introduced will have a positive effect on the overall energy costs associated with air handling units.
