Multi-story and underground car parks offer a logical solution in bustling urban areas. However, they come with stringent ventilation and fire safety requirements, which complicate the project and incur significant costs.  <\/p><p> <\/p><p>These systems utilize reliable Invertek Drives frequency converters <strong>Optidrive Eco<\/strong>, which allow for significant savings in installation and operating costs. Additionally, the internal height of the premises is increased as there is no longer a need for unsightly ventilation ducts. Instead of galvanized ducts, numerous impulse or jet fans are installed, strategically positioned throughout the car park. This powerful combination of fans ensures regular air changes during normal operation and can rapidly remove smoke and fumes in an emergency fire situation.   <\/p><p> <\/p><p>The precise location of the fans is calculated using computational fluid dynamics. This allows the designer to determine optimal fan positions before installation. Crawford Controls developed a control system that uses Invertek Drives Optidrive Eco frequency converters. The system controls fan activation and adjusts the set speed based on the CO level detected over a specific period. The system also responds to fire or smoke detection by activating an emergency smoke extraction mode.    <\/p><p> <\/p><p>Each car park is equipped with carbon monoxide detectors and a fire or smoke detection system. If CO levels do not decrease within a certain period, a second, higher detection level further increases fan speed, and so on. This method of controlling fan activation and speed allows for significant energy savings and reduces unnecessary wear and tear. In the event of fire detection, the system uses the inverter&#8217;s soft-start function to increase all fans to maximum speed, while ensuring minimal energy and mechanical load on the entire system.    <\/p><p><\/p><p><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a872a8e elementor-widget elementor-widget-image\" data-id=\"a872a8e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"678\" height=\"534\" src=\"https:\/\/simeksa.lt\/wp-content\/uploads\/2024\/04\/hvac-system-control.png\" class=\"attachment-large size-large wp-image-13514\" alt=\"Controlling your HVAC System\" srcset=\"https:\/\/simeksa.lt\/wp-content\/uploads\/2024\/04\/hvac-system-control.png 678w, https:\/\/simeksa.lt\/wp-content\/uploads\/2024\/04\/hvac-system-control-600x473.png 600w, https:\/\/simeksa.lt\/wp-content\/uploads\/2024\/04\/hvac-system-control-300x236.png 300w\" sizes=\"(max-width: 678px) 100vw, 678px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d237e0d elementor-widget elementor-widget-heading\" data-id=\"d237e0d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-large\">Technical and Commercial Challenges<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-749cdc2 elementor-widget elementor-widget-text-editor\" data-id=\"749cdc2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>When a system contains as many as <b>40 fans<\/b>, it is uneconomical to use a separate converter for each fan. Furthermore, the fire environment requires controllers to be protected for at least 1 hour, making it difficult to install any control components within the car park itself. All fire-related control devices must be located away from the car park, in a safe area, typically a plant room, with only fire detection devices installed in the car park. Unfortunately, converters are not ideally suited for long cables and can encounter issues.   <\/p><p> <\/p><p>With the assistance of <b>Invertek Drives,<\/b> <b>Crawford Controls<\/b> successfully overcame technical and economic challenges by <strong>operating groups of fans from a single frequency converter<\/strong>, with parallel cables up to 800m long!

utilized to develop a car park ventilation system, ensuring sufficient airflow and smoke extraction during a fire. The system replaced unsightly ventilation ducts with strategically placed impulse or jet fans, connected to larger extraction fans. The system was controlled by Invertek Optidrive Eco drives and equipped with carbon monoxide detectors and a fire and smoke detection system. The use of a single inverter for multiple fan groups allowed for cost and energy savings, while overcoming technical challenges such as long cable distances.   <\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_angie_page":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"normal-width-container","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"page_builder":"","footnotes":""},"categories":[300,218],"tags":[296],"class_list":["post-13512","post","type-post","status-publish","format-standard","hentry","category-application-analysis","category-frequency-inverters","tag-optidrive-eco-2"],"acf":[],"_links":{"self":[{"href":"https:\/\/simeksa.lt\/en\/wp-json\/wp\/v2\/posts\/13512","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/simeksa.lt\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/simeksa.lt\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/simeksa.lt\/en\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/simeksa.lt\/en\/wp-json\/wp\/v2\/comments?post=13512"}],"version-history":[{"count":1,"href":"https:\/\/simeksa.lt\/en\/wp-json\/wp\/v2\/posts\/13512\/revisions"}],"predecessor-version":[{"id":13515,"href":"https:\/\/simeksa.lt\/en\/wp-json\/wp\/v2\/posts\/13512\/revisions\/13515"}],"wp:attachment":[{"href":"https:\/\/simeksa.lt\/en\/wp-json\/wp\/v2\/media?parent=13512"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/simeksa.lt\/en\/wp-json\/wp\/v2\/categories?post=13512"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/simeksa.lt\/en\/wp-json\/wp\/v2\/tags?post=13512"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
