It consists of a blower, heating or cooling elements, filter racks, sound attenuators and dampers. It is usually connected to a ductwork system that distributes the conditioned air through the building and returns it to the AHU.<\/p>\r\n\r\n<p>Sometimes, AHU&#8217;s discharge and admit air directly to and from the space without ductwork.<\/p>\r\n\r\n<p>With the growing emphasis on energy performance in buildings, and new standards to study and improve energy efficiency, buildings need automation &amp; control systems to achieve high levels of energy efficiency.<\/p>\r\n\r\n<p>HVAC is one area where huge amount of power is consumed, and where plants with energy-optimised design, installation and commissioning are a must.\u00a0Automation with AHU-specific functions ensures more systems&#8217; energy efficiency, operational reliability and availability. Automation also monitors room and outdoor temperatures to reduce cooling energy needs and improve comfort levels.<\/p>\r\n\r\n<p><strong><em>MESSUNG is an Automation Partner capable of Supplying Solutions to any Project of Air Handling Units and Environment Control Systems.\u00a0<\/em><\/strong><\/p>\r\n<p>\u00a0<\/p>\r\n\r\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-104\" src=\"https:\/\/www.messung.com\/blog\/wp-content\/uploads\/2020\/03\/Blog-Images-09-03-20_Artboard-7-1024x551.png\" alt=\"HVAC Solutions, PLC for Industrial Automation\" width=\"580\" height=\"312\" srcset=\"https:\/\/www.messung.com\/blog\/wp-content\/uploads\/2020\/03\/Blog-Images-09-03-20_Artboard-7-1024x551.png 1024w, https:\/\/www.messung.com\/blog\/wp-content\/uploads\/2020\/03\/Blog-Images-09-03-20_Artboard-7-300x161.png 300w, https:\/\/www.messung.com\/blog\/wp-content\/uploads\/2020\/03\/Blog-Images-09-03-20_Artboard-7-768x413.png 768w, https:\/\/www.messung.com\/blog\/wp-content\/uploads\/2020\/03\/Blog-Images-09-03-20_Artboard-7-1536x826.png 1536w, https:\/\/www.messung.com\/blog\/wp-content\/uploads\/2020\/03\/Blog-Images-09-03-20_Artboard-7-1170x629.png 1170w, https:\/\/www.messung.com\/blog\/wp-content\/uploads\/2020\/03\/Blog-Images-09-03-20_Artboard-7-750x404.png 750w, https:\/\/www.messung.com\/blog\/wp-content\/uploads\/2020\/03\/Blog-Images-09-03-20_Artboard-7.png 1551w\" sizes=\"auto, (max-width: 580px) 100vw, 580px\" \/><\/figure>\r\n<p>\u00a0<\/p>\r\n\r\n<h3 class=\"wp-block-heading\"><strong>Case Study:<\/strong><\/h3>\r\n\r\n<p><strong>\u201cOur Customer is a Bengaluru based company involved into manufacturing of Products like Metal Working Tools, Mining, Foundation Drilling cutting Tools, Tungsten carbide wear components etc.. required for Industries like Aerospace, Additive manufacturing, Machine Tool Industry, Energy, Earthworks.\u201d<\/strong><\/p>\r\n<p>\u00a0<\/p>\r\n\r\n<h3 class=\"wp-block-heading\"><strong>Basic AHU for Coating Room:<\/strong><\/h3>\r\n\r\n<p>The project required Messung\u2019s solution to ensure that the coating room is maintained under 5 Pa Negative pressure with respect to ambient and within the room temperature zone of 21.1 Deg.
