An economizer is a mechanical device used to reduce energy consumption. Economizers recycle energy produced within a system or leverage environmental temperature differences to achieve efficiency improvements.

Economizers are commonly used in data centers to complement or replace cooling devices like computer room air conditioners (CRACs) or chillers. Data center economizers generally have one or more sets of filters to catch particulates that might harm hardware. These filters are installed in the duct work connecting an outside environment to a data center. Outside air also must be monitored and conditioned for the appropriate humidity levels, between 40% and 55% relative humidity, according to ASHRAE.

There are two versions of the device used in data centers: air-side economizers and water-side economizers. Economizers can save data center operators substantial operating costs. , economization has the potential to reduce the annual cost of a data center's energy consumption by more than 60 percent. Use of cooler external environmental temperatures to preserve hardware is an important component in sustainable green computing practices in general. Unfortunately, economizers are only useful for data centers located in cooler climates. This Web page has been archived on the Web. Information Archived on the Web.

And a building's heating, ventilation and air conditioning (HVAC) system is no different in this respect than a mobile phone or a security system. Enhancing an HVAC system's brain has several benefits, and there are many different options for making the system smarter. Maybe the most notable of the available HVAC upgrades is an advanced digital economizer control (ADEC). And finding an HVAC technician with experience working with ADECs is pivotal for realizing the highest rate of efficiency out of an ADEC or any other HVAC upgrade. An ADEC is a retrofit upgrade that can be added to a packaged HVAC unit or used to replace existing analog or nonfunctional economizer controls. ADECs are "smarter" because they are digital, which makes them more precise;

they detect and report problems with HVAC equipment, including dampers and sensors; and they can determine if an economizer is working properly. All of these factors help to maximize the efficiency of an HVAC unit. ADECs are more effective at utilizing the benefits of an economizer, which opens the building's dampers to allow more outside air into the building when it enhances the temperature conditioning of the indoor space. everlast ac unitThe improved efficiency comes from using cooler outdoor air to keep indoor temperatures comfortable. rheem ac unit costThis aspect of the system essentially acts to provide free cooling to indoor spaces when it is colder outside, reducing both energy costs and consumption. small wine cellar cooling units ukBusiness owners can retrofit their existing analog economizer control for a packaged HVAC unit with an ADEC system such as the Belimo Zip or the Honeywell Jade W7220.

ADECs offer further opportunities for smart enhancements to HVAC systems when they are combined with CO2 sensors to create a Demand Control Ventilation (DCV) kit. The CO2 sensor/DCV combination allows dampers to be closed below design if the space isn't being fully utilized. Variable Frequency Drives (VFDs) can also be integrated into the ADEC system as part of an Enhanced Ventilation Control (EVC) package, such as a Transformative Wave Catalyst. An integrated VFD allows the ventilation rate to be reduced if occupancy of a space is below design. What are the benefits of a brainier HVAC system? ADECs provide several benefits for businesses of all kinds, including: How does a smarter HVAC system improve a business? There are two primary ways that an ADEC-aided smart HVAC system can benefit a business: What types of businesses benefit the most from a smart HVAC system? Any commercial facility with a rooftop air conditioner that is fitted with an economizer can benefit from retrofitting that unit with an ADEC.

However, the following types of businesses and buildings can realize the greatest advantages: How can working with an HVAC contractor make an HVAC system smarter? In combination, a qualified HVAC contractor and an ADEC can be a powerful resource for a business. Finding an HVAC contractor with extensive knowledge of ADECs (as well as DCVs, VFDs and ECVs) can take a business's energy efficiency and cost-cutting capabilities to the next level. The information that ADECs provide pave the way for working more effectively with a qualified HVAC contractor. The contractor will be able to detect problems with equipment as soon as they arise, as opposed to waiting until they become much more costly repairs or require total replacement. Some ADECs even have the capability to send information via email or text when maintenance repair is needed. Before moving forward with any HVAC retrofits, upgrades or replacements, be sure to contact a qualified HVAC contractor. The contractor can inform business owners on benefits for a particular facility for any HVAC project, projecting initial costs and long-term savings to understand which option is best suited for the business.
