(opens in a new tab)\">Air Movement and Control Association\u00a0(AMCA) International Inc.<\/a> The Freshman Series is a single room air handler that is certified by AMCA International\u2019s Certified Ratings Program (CRP) for both air and sound performance.\u00a0 The CRP was amended to include fully packaged single room air handlers in its Product Rating Manual for Fan Air Performance. <\/p>\n\n\n\n<p>The certification and the amendment are developments for the engineering community, educators and students because they open the door to acoustic design in classroom environments. The AMCA certification of the Freshman Series means that the sound and air flow test data gathered in an AMCA certified laboratory and is third party certified to be accurate. Test methods used to gather sound data on the Freshman Series comply with the following standards:<\/p>\n\n\n\n<ul><li>AHRI\n260 \u2013 Sound rating of ducted air moving and condition equipment<\/li><li>AMCA\nStandard 300-08 \u2013 Reverberant room method for sound testing of fans<\/li><li>ANSI\/ASA\nStandard S12.60-2010 \u2013 Acoustical performance criteria, design requirements and\nguidelines for schools <\/li><\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Reliable Prediction of Background Noise<\/h4>\n\n\n\n<p>Prior to this certification, engineers had no way of comparing or predicting the sound performance of air handling equipment in a classroom because test methodology tends to vary from manufacturer to manufacturer, yielding data that is impossible to compare and can be misleading.\u00a0 Testing in an AMCA certified reverberant lab eliminates testing variables and provides data that is both accurate and relevant to classroom applications.\u00a0 <\/p>\n\n\n\n<p>\u201cThis brings a whole new comfort level to those specifying equipment for the classroom because it means they know exactly what they are going to get when they specify an air handler certified under this particular standard,\u201d says Mark Long, manager of engineering for Systemair, parent company of Changeair.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Better Acoustics for All <\/h4>\n\n\n\n<p>Single room air handlers like the Freshman Series offer design flexibility, efficiency and comfort for classroom spaces; however, engineers and school boards often avoid them because of the potential for excessive mechanical noise. AMCA\u2019s sound performance certification removes that uncertainty. <\/p>\n\n\n\n<p>Certified test results of the Freshman Series equipment shows that it meets background noise criteria that is referenced in green school guidelines, meaning that its operation within a space should not compromise students\u2019 ability to understand the teacher.\u00a0In fact, a school cannot receive LEED certification without meeting AMCA 300 and ANSI S12.60. Unfortunately, few schools have funding to become LEED certified, so engineers have been limited in their ability to protect students from excessive mechanical noise. Now they have the option of specifying equipment that is AMCA certified for air and sound and meets ANSI S12.60 for acoustical performance.<\/p>\n\n\n\n<p>\u201cFew things are as critical to a learning environment as classroom acoustics. Having access to certified sound data empowers schools and engineers to make better choices for students. It\u2019s a major step forward in the journey toward quieter classrooms,\u201d says Kevin McGachy, product manager for Changeair. <\/p>\n\n\n\n<p>AMCA certified Freshman\nSeries air handlers are available in a variety of configurations, including\nthose with heating and\/or cooling coils, outdoor air ventilation and even\nenergy recovery. All sizes and almost all configurations of the Freshman air\nhandler have been AMCA certified.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The future of classroom environments has gotten quieter thanks to the certification of Changeair\u2019s Freshman Series Vertical Air Handler by the Air Movement and Control Association\u00a0(AMCA) International Inc.
