The main require\u00adment of the project was to reduce the power consump\u00adtion of the fans and to exploit further energy saving poten\u00adtial by estab\u00adlishing a control system. The upgrade was also intended to extend the service life of the AHUs. The contract for the retrofit was awarded to Jon Davies and his company Qey Energy Solu\u00adtions, which worked closely with ebm-papst Middle East and Taka Solu\u00adtions to develop an effi\u00adcient solu\u00adtion.<\/p>\n\n\n\n<h2 class=\"wp-block-heading no-clear\">An effi\u00adcient complete solu\u00adtion<\/h2>\n\n\n\n<p>In order to keep the down\u00adtime of the AHUs as short as possible during the retrofit work, they were upgraded one after the other. However, this meant that during the down\u00adtime, parts of the building could no longer be supplied with fresh air. This time pres\u00adsure meant that the new fans had to be installed quickly and without compli\u00adca\u00adtions. Qey\u2019s \u201cMatrixAir+ EC\u201d solu\u00adtion made this possible. This fan package, consisting of EC fans, fan terminal boxes, fan bulk\u00adheads and control panels, was deliv\u00adered directly to the AHUs as a pre-prepared complete solu\u00adtion and installed.<\/p>\n\n\n\n<div class=\"wp-block-group alignfull mgznkr-cta-retrofit-banner\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<style>\n.mgznkr-cta-retrofit-banner .alignwide.banner-width {\n  max-width: 100%;\n  width: 1240px;\n  margin: 0 auto;\n--mark-bgcolor: #00a633;\n--mark-color: white;\n}\n@media (max-width: 781px) {\n.mgznkr-cta-retrofit-banner .wp-block-cover .wp-block-cover__image-background {\nobject-position: 17% 50%!important;\n}\n.mgznkr-column-spacer p {display: none; }\n}\n@media (min-width: 782px) {\n.mgznkr-column-spacer p a {\n  min-height: 290px;\n  min-width: 100%;\n  display: block;\n  border-radius: 50px;\nfont-size: 0;\n}\n}\n<\/style>\n\n\n\n<div style=\"height:32px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-cover is-light\" style=\"min-height:350px;aspect-ratio:unset;\"><span aria-hidden=\"true\" class=\"wp-block-cover__background has-background-dim-0 has-background-dim\" style=\"background-color:#e0e6e6\"><\/span><img decoding=\"async\" class=\"wp-block-cover__image-background wp-image-36590\" alt src=\"https:\/\/ebmpapst-7237.kxcdn.com\/de\/files\/2024\/12\/2412_Banner-Retrofit-1.jpg\" data-object-fit=\"cover\"><div class=\"wp-block-cover__inner-container is-layout-constrained wp-block-cover-is-layout-constrained\">\n<div class=\"wp-block-columns alignwide banner-width is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:560px\">\n<h2 class=\"wp-block-heading mgznkr-click has-white-color has-text-color has-link-color wp-elements-98ef17eb21ecd509a55e5e5eacc3f4f6\" id=\"retrofit-banner-head\" style=\"font-size:1.6em;text-transform:uppercase\"><mark><a href=\"https:\/\/www.ebmpapst.com\/de\/en\/industries\/fanupgrade.html#download\" target=\"_blank\" rel=\"noreferrer noopener\">More effi\u00adciency, less costs: Retrofit<\/a><\/mark><\/h2>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading no-margin-top\" style=\"font-size:1em\">Retrofit of fans with ebm-papst<\/h3>\n\n\n\n<p>Retro\u00adfitting existing fans in venti\u00adlation and cooling systems with effi\u00adcient EC fans and demand-based oper\u00ada\u00adtion can save up to 60 % energy and costs \u2013 and protect the envi\u00adron\u00adment at the same time.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button has-custom-font-size is-style-fill mgznkr-click\" id=\"retrofit-banner-button\" style=\"font-size:18px\"><a class=\"wp-block-button__link has-background wp-element-button\" href=\"https:\/\/www.ebmpapst.com\/de\/en\/industries\/fanupgrade.html#download\" style=\"background-color:#0072bb\" target=\"_blank\" rel=\"noreferrer noopener\">Find more infor\u00adma\u00adtion here <i class=\"mgznkr-icon fa fa-chevron-right fas\"><\/i><\/a><\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-column mgznkr-column-spacer is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:55%\">\n<p class=\"mgznkr-click\" id=\"retrofit-banner-img\"><a href=\"https:\/\/www.ebmpapst.com\/de\/en\/industries\/fanupgrade.html#download\" target=\"_blank\" rel=\"noreferrer noopener\">More effi\u00adciency, less costs: Retro\u00adfitting fans with ebm-papst<\/a><\/p>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<div style=\"height:36px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<\/div><\/div>\n\n\n\n<p>When it came to the first compo\u00adnent, the choice fell on EC centrifugal fans from ebm-papst\u2019s RadiPac series.

Since the RadiPac is supplied as a plug &amp; play solu\u00adtion, commis\u00adsioning the EC fan is also a quick process.

This redun\u00addant design increases the depend\u00adability of the system and ensures greater oper\u00ada\u00adtional reli\u00ada\u00adbility (Fig. 3). If one fan fails, the other EC fans compen\u00adsate for the missing air volume. This provides the neces\u00adsary reli\u00ada\u00adbility, espe\u00adcially for large systems, and even more so in partic\u00adu\u00adlarly hot regions such as Dubai. Another reason for a FanGrid was to extend the system\u2019s service life. This can be achieved by oper\u00adating several small fans at partial load as required instead of one large fan constantly at full load.<\/p>\n\n\n\n<p>Another advan\u00adtage of this type of setup is that air can flow more evenly through upstream and down\u00adstream compo\u00adnents such as filters and heat exchangers. This results in more effi\u00adcient filtering of the air, as well as better heat transfer perfor\u00admance \u2013 which in turn reduces the oper\u00adating costs of the system. Several small fans also usually require less instal\u00adla\u00adtion space and are lighter than a single large fan, making replace\u00adment easier.<\/p>\n\n\n<div class=\"wp-block-image xxtra wp-image-16576 size-large\">\n<figure class=\"alignleft\"><img loading=\"lazy\" decoding=\"async\" width=\"960\" height=\"609\" src=\"https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Bild_3_FanGrid_2-960x609.jpg\" alt class=\"wp-image-16576\" srcset=\"https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Bild_3_FanGrid_2-960x609.jpg 960w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Bild_3_FanGrid_2-660x419.jpg 660w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Bild_3_FanGrid_2-260x165.jpg 260w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Bild_3_FanGrid_2-450x286.jpg 450w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Bild_3_FanGrid_2-300x190.jpg 300w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Bild_3_FanGrid_2.jpg 1024w\" sizes=\"auto, (max-width: 960px) 100vw, 960px\"><figcaption class=\"wp-element-caption\">Fig. 3: In a FanGrid, the Radi\u00adPacs are installed next to or above one another and oper\u00adated in parallel.

(Fig. | ebm-papst)<\/figcaption><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\">Energy savings with EC tech\u00adnology<\/h2>\n\n\n\n<p>The main aim of the retrofit was to save energy, which is why a fan with an EC motor was chosen. Its high motor effi\u00adciency level of over 90% alone makes large savings possible compared to the AC motor. In addi\u00adtion, with the old AC fans, only two oper\u00adating levels were possible: either they were off, or they were oper\u00adated at maximum speed; there was nothing in between due to the lack of control elec\u00adtronics. This means that regard\u00adless of the actual occu\u00adpancy of the building, all systems always ran at full power, even if at certain times it would have been suffi\u00adcient to supply indi\u00advidual parts of the building with a lower air volume.<\/p>\n\n\n\n<p>By contrast, EC fans can be contin\u00adu\u00adously controlled between 0 and 100%, meaning that the speed can always be adjusted to meet demand. This results in signif\u00adi\u00adcant poten\u00adtial for savings, as the power consump\u00adtion increases or falls in line with the speed to the power of three (P~n\u00b3). So if the speed is reduced by half compared to the nominal speed, the power consump\u00adtion is reduced by a factor of 8 and is there\u00adfore only 12.5 % of the rated output. If, on the other hand, half of the AC fans are switched off and the other half are still oper\u00adated at full load, only 50% of the power consump\u00adtion can be saved.<\/p>\n\n\n<div class=\"wp-block-image size-medium wp-image-16577\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"660\" height=\"419\" src=\"https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Bild_4_Steuerung-660x419.jpg\" alt class=\"wp-image-16577\" srcset=\"https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Bild_4_Steuerung-660x419.jpg 660w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Bild_4_Steuerung-960x609.jpg 960w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Bild_4_Steuerung-260x165.jpg 260w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Bild_4_Steuerung-450x286.jpg 450w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Bild_4_Steuerung-300x190.jpg 300w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Bild_4_Steuerung.jpg 1024w\" sizes=\"auto, (max-width: 660px) 100vw, 660px\"><figcaption class=\"wp-element-caption\">Fig. 4: The demand-based control system regu\u00adlates the air volume flow depending on the time. (Fig. | ebm-papst)<\/figcaption><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\">Demand-based fresh air supply<\/h2>\n\n\n\n<p>The second part of the retrofit involved upgrading the control system. The Swiss Tower already had a building manage\u00adment system; the aim with regard to the venti\u00adlation systems was now to develop a time-depen\u00addent strategy for control\u00adling them. One advan\u00adtage was that, thanks to the secu\u00adrity scans at the entrance and exit, data was already avail\u00adable on the building\u2019s occu\u00adpancy, which varied according to the time of day. Working with Taka Solu\u00adtions, Qey used this data to deter\u00admine the airflow require\u00adments on a time-depen\u00addent basis and programmed an internal schedule using soft\u00adware devel\u00adoped specif\u00adi\u00adcally for retrofit projects (Fig. 4).<\/p>\n\n\n\n<p>Office occu\u00adpancy is lower in the morn\u00adings and evenings, which is why the power is reduced at these times, whereas during the after\u00adnoon the building is at its highest capacity, temper\u00ada\u00adtures tend to be at their hottest, the AHUs have to deliver a greater volume of air, and there is the most demand for cooling (Fig. 5). The ideal prereq\u00adui\u00adsite for this is the RadiPac\u2019s RS485\/MODBUS RTU inter\u00adface, which enables the fans to be intel\u00adli\u00adgently controlled while also allowing the oper\u00adating data of each indi\u00advidual fan to be moni\u00adtored. The RadiPac also enables differ\u00aden\u00adtial pres\u00adsure measure\u00adment, as it has a pres\u00adsure tap for connecting a differ\u00aden\u00adtial pres\u00adsure trans\u00admitter. This also allows conclu\u00adsions to be drawn about the air flow rate that is currently being handled. Thanks to the MODBUS inter\u00adface, Qey\u2019s soft\u00adware can monitor and control the speed as spec\u00adi\u00adfied by the schedule, and also monitor the air flow, energy consump\u00adtion and, if neces\u00adsary, alarms and quickly initiate coun\u00adter\u00admea\u00adsures.<\/p>\n\n\n<div class=\"wp-block-image xxtra wp-image-16580 size-large\">\n<figure class=\"alignleft\"><img loading=\"lazy\" decoding=\"async\" width=\"960\" height=\"471\" src=\"https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Fig_5_diagramm_2_EN-960x471.jpg\" alt class=\"wp-image-16580\" srcset=\"https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Fig_5_diagramm_2_EN-960x471.jpg 960w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Fig_5_diagramm_2_EN-660x324.jpg 660w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Fig_5_diagramm_2_EN-260x127.jpg 260w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Fig_5_diagramm_2_EN-450x221.jpg 450w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Fig_5_diagramm_2_EN-300x147.jpg 300w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/10\/Fig_5_diagramm_2_EN.jpg 1024w\" sizes=\"auto, (max-width: 960px) 100vw, 960px\"><figcaption class=\"wp-element-caption\">Figure 5 \/ Char\u00adac\u00adter\u00adistic curve: Here, the modu\u00adla\u00adtion of the air flow over the day can be seen thanks to the time-depen\u00addent control system.
