In this article, you will find what you need to know about economizers and learn how to identify whether your system has one.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_an_HVAC_Economizer\"><\/span>What is an HVAC Economizer?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>As can be deduced from the name, an HVAC economizer is a device that enhances the economy of using the HVAC system. An economizer is placed within the exterior parts of the HVAC system, most often on the rooftop of the facility or property.<\/p>\n<p>This device constantly evaluates the temperature and humidity of the outside air and when appropriate, it cuts or decreases the work load on the air-conditioning system and utilizes the outside air for cooling of the building.<\/p>\n<p>The task of air quality assessment would be done by a control logic and some sensors to feed the measurement signals to the controller to identify how much air might be needed to be directed from outside into the building. The amount of inlet air is mechanically adjusted by dampers.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Different_Types_of_HVAC_Economizers_Work\"><\/span>How Different Types of HVAC Economizers Work<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>An HVAC economizer comes in many types that are chosen based on the requirements of the HVAC system, be it technical or financial requirements.<\/p>\n<p><img decoding=\"async\" class=\"size-full wp-image-855 aligncenter\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/06\/09-AT-Rycroft-HVAC-energy-efficiency-fig01-300x214-1.jpg\" alt=\"HVAC economizer diagram\" width=\"300\" height=\"214\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/06\/09-AT-Rycroft-HVAC-energy-efficiency-fig01-300x214-1.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/06\/09-AT-Rycroft-HVAC-energy-efficiency-fig01-300x214-1-100x70.jpg 100w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/>The first and the simplest type of an HVAC economizer is the dry-bulb economizer. These economizers only compare the dry-bulb temperature of interior parts of the building with the dry-bulb temperature of the outside air to regulate the amount of air inlet to the building. Due to their sensing logic, they would only be useful in arid climates where the air humidity levels are low.<\/p>\n<p>To makeup for the shortcoming of dry-bulb economizers, a single enthalpy economizer also measures the humidity level. This has resulted in these economizers dominating the market for effective HVAC economizer solutions.<\/p>\n<p>A differential enthalpy economizer is even more sophisticated than the other two types. In this type, the system also measures the amount of return air as well as the air to be directed outside. These systems are mostly seen for single large HVAC systems that are to manage distribution of air to various number of zones.<\/p>\n<p>There are also integrated differential enthalpy economizers in which the measurements and operation is pretty much identical to the previous type, except that the economizer\u2019s controller first compares the outside temperature with the inside\u2019s to see if the outside air would be sufficient for delivering the cooling task without starting the compressor and if the cooling was not sufficient, compressor would then be started.<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_benefits_of_HVAC_Economizer\"><\/span>The benefits of HVAC Economizer<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>An HVAC economizer brings many significant benefits to the air-conditioning system, and the benefits of knowing about economizers could go to both the users and the technicians of the HVAC industry.<br \/>\nOne can consider the following three advantages of arranging an HVAC economizer in the system:<\/p>\n<p>1. Since the A\/C units consume a lot of energy, having them running for long hours would significantly increase the electricity bill, and it is something that no one wants. By actively comparing the inside air conditions against the outside\u2019s, and using outside air to sometimes take on the responsibility of air conditioning job instead of constant running of the A\/C unit, a lot of energy could be saved that leads to considerable amounts of financial savings as well.<\/p>\n<p>2. By monitoring the inside and outside air and increasing the use of outside air, an HVAC economizer also increases the level of ventilation which is a factor contributing to improvement of the air quality in the intended space.<\/p>\n<p>3. Adding interruptions to the operation of A\/C units not only lowers the amount of money savings through less energy consumption, but it would improve the lifespan of unit by lowering the work load on it. This is due to the decrease of wear and tear which is in part due to operation of the HVAC system. This would also raise the system\u2019s reliability by lowering breakdowns, as well as less maintenance costs.<\/p>\n<p>Knowing about these benefits could motivate the users of HVAC systems to make sure they have HVAC economizers to optimize their operation and lower their costs in the long run.<br \/>\nIn addition, From a technician\u2019s standpoint, knowing about these systems could provide the means of negotiation to persuade the end user to install or maintain these devices that would later save a lot of money for them despite adding to the initial costs of the building the HVAC system.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Checking_the_HVAC_System_for_Economizers\"><\/span>Checking the HVAC System for Economizers<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>It could be hard for a non-expert such as the owner\/manager of a property or a facility to know whether an economizer is installed within the HVAC system. Moreover, identification of proper functioning of the economizer is another important task that requires professional help.<\/p>\n<p>Therefore, it is highly recommended for the user to seek some professional expertise to assess the current state of the HVAC system regarding economizers and take the necessary steps to have it in good shape.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"More_on_HVAC_Economizers\"><\/span>More on HVAC Economizers<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>You can learn some interesting details about hvac economizers in the four-part video <a href=\"https:\/\/www.youtube.com\/watch?v=3FtF0ht32-A\" target=\"_blank\" rel=\"noopener\">here<\/a>.<\/p>\n<h3><b>Buy Equipment or Ask for a Service<\/b><\/h3>\n<p>By using Linquip RFQ Service, you can expect\u00a0to receive quotations from various suppliers across multiple industries and regions.<\/p>\n<p style=\"text-align: center;\"><strong><a href=\"http:\/\/linquip.com\/get-quote?utm_source=blog&amp;utm_medium=content&amp;utm_campaign=product_list&amp;utm_term=product_list&amp;utm_content=rfq\" target=\"_blank\" rel=\"noopener\">Click Here to Request a Quotation From Suppliers and Service Providers<\/a><\/strong><\/p>\n<p><em><strong>Read More on Linquip<\/strong><\/em><\/p>\n<ul>\n<li><span style=\"text-decoration: underline; font-family: verdana, geneva, sans-serif;\"><strong><span style=\"font-size: 10pt;\"><a href=\"https:\/\/www.linquip.com\/blog\/hvac-maintenance\/\" target=\"_blank\" rel=\"noopener\">A Brief and Easy Introduction to HVAC Maintenance<\/a><\/span><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline; font-family: verdana, geneva, sans-serif;\"><strong><span style=\"font-size: 10pt;\"><a href=\"https:\/\/www.linquip.com\/blog\/what-is-hvac\/\" target=\"_blank\" rel=\"noopener\">What is HVAC?
