The computing power we know as the Internet actually resides in millions of data centers that house rows and rows of computer servers. And each data center represents a unique HVAC challenge: How to keep the equipment cool, the air pure and the humidity low. Providing the ideal operating conditions for a room full of computers requires the best that the HVAC market can offer.  Data centers come in all shapes, sizes and configurations. Some are huge facilities that serve the needs of giants, such as Google, Amazon and Microsoft. Others are smaller and might contain the servers for a single company. In every case, there is expensive equipment operating, creating enormous amounts of heat and there is important data to be preserved. Air quality and temperature monitoring Data centers have a narrower range of acceptable environmental factors when compared to typical buildings Air quality and temperatures are monitored around the clock, and even small discrepancies can undermine the whole operation. Data centers have a narrower range of acceptable environmental factors when compared to typical buildings. ASHRAE provides guidelines and best practices for mission-critical facilities, which should be followed by any contractor working with data centers. The layout of a data center is an important consideration – what is the location of servers and other key equipment? Appropriate parameters in various zones ensure correct temperatures and humidity levels. Managing power loads Access must be maintained to the electrical infrastructure and supplies, and attention must be paid to electric loads. Typically, an HVAC system uses its own electrical supply, separate from the system that the servers depend on. This approach helps with managing power loads. Often server rooms have raised floors to provide technicians access to the infrastructures. Fans placed under the floor can discharge air in a wider pattern for more uniform cooling. Server rooms may also have higher ceilings to provide room for large equipment racks. These features can impact air flow, temperature and humidity and should be incorporated into HVAC system designs. ‘Hot aisle, cold aisle’ approach Managing higher heat loads of computer servers arranged in rows at data centers can use a ‘hot aisle, cold aisle’ approach. Cold air intakes and hot air exhausts face alternating rows. Because of moisture concerns, only plumbing that relate to fire suppression should be located near the server rooms. Server rooms typically do not have windows or outside doors or outside-facing walls. Air filtration For air quality, filters eliminate the smallest particles such as dust or pollen. HEPA filters are effective For air quality, filters eliminate the smallest particles such as dust or pollen. HEPA filters are effective. Other factors include new motor types, fewer moving parts, and more sensors to provide predictive maintenance. Preventive maintenance is a better approach than facing the possible dire consequences of an emergency. Keeping spare parts on hand is a good way to minimize risk. Variable-speed fans save energy, and they use motors that do not require belts, pulleys or bearing hardware for cleaner operation and less contamination, and less frequent maintenance. However, monthly HVAC inspections should be implemented to ensure maximum data center uptime. Mission-critical HVAC systems Mission-critical HVAC systems for data centers fall into two categories. One is Computer Room Air Conditioners (CRAC), which use compressors and are deployed for perimeter cooling. The other is Computer Room Air Handlers (CRAH), which use water from a centralized chiller and a control valve to provide cooling. Stand-alone ultrasonic units take the place of internal humidifiers on CRAC and CRAH units.

Data is playing an increasingly important role in smart buildings. Analysis of building system data is guiding an expansion of capabilities in the smart building environment, making building systems - including HVAC - more efficient, effective and smarter. The growth of intelligence in the HVAC market was among the more prominent industry trends in 2020. This article will revisit some of the year’s most popular articles on HVACinformed.com that focused on the trend toward more intelligent systems. "I don’t think many would disagree that the most talked about trend in the HVAC market is smart technology,” says Chris Windass of Incentiv Tec in an HVACinformed.com Expert Panel Roundtable article. “Smart technology like mobile apps allow building managers to control HVAC technology from one centralized point. With this smart technology, HVAC will be able to identify and alert building managers when maintenance is needed or assets have failed to operate.” smarter building technology A Johnson Controls survey found that 77% of organizations planned to make investments in energy efficiency and smarter building technology in 2020. “A complete overhaul of legacy systems is not necessary as small investments today can help position a facility to more easily adopt technologies at scale in the future,” says Lisa Brown, Senior National Director of Municipal Infrastructure and Smart Cities at Johnson Controls. More Intelligence in Home Systems Google’s Nest smart thermostat is offering a new capability that will alert homeowners of problems “As a first step, it’s important for building owners to conduct an assessment and establish a strategy that defines a comprehensive set of requirements and prioritizes use-cases and implementations. From there, incremental investments and updates can be made over a realistic timeline.” Smart systems are also a big part of residential HVAC systems. For example, Google’s Nest smart thermostat is offering a new capability that will alert homeowners of problems with the operation of their HVAC systems based on artificial intelligence (AI) algorithms that analyze system performance. The technology will empower Nest Learning thermostats to provide “early warning” of HVAC problems and even direct homeowners to a repair company. Remote Troubleshooting Emerges Sensors are another element of smart buildings. The Internet of Things (IoT) has enabled more sensors of different types to be deployed in more locations throughout the building easier than ever before. The point of installing and using IoT sensors is to gain deeper insight into how buildings are performing, and ensure buildings are healthier, more productive for people to work in, more effective to run and more energy efficient. In-room sensors, such as temperature, air quality and occupancy, work with the IoT to improve building performance. The benefits of IoT sensors are that they are easy to install, both physically and from a commissioning perspective. Remote troubleshooting is another smart capability that is generating interest. CoolAutomation’s Remote HVAC Service Solution enables HVAC service providers to remotely troubleshoot issues by analyzing real-time and historic data trends and analysis. Communicating in Smart Buildings They receive automatic error and anomaly notifications in their office or on their mobile phones They receive automatic error and anomaly notifications in their office or on their mobile phones. “The remote service solution provides the tools that HVAC service providers need to offer remote services to their existing clients while attracting new customers who understand the value of remote service for their business,” says Roy Muchtar, VP of Products at CoolAutomation. Communication is a central aspect of smart building systems, and now there’s a better option: a high-speed wireline communication standard called HD-PLC that is developed specifically for today’s industrial IoT and smart building applications. In 2017, after careful evaluation of various technologies, LonMark International adopted HD-PLC as its new channel standard. smart home standards And last October, the Consumer Technology Association (CTA) approved ANSI/CTA 709.8 LON HD-PLC (High Definition Power Line Communication) as a new standard by the American National Standards Institute (ANSI). Also related to communication, the Zigbee Alliance seeks to promote collaboration in the Internet of Things by creating, evolving, and promoting universal open standards that enable all objects to connect and interact. A quick search also provides a manual, wiring diagram and video training content for that specific unit Their effort took off when Amazon, Apple, Google and the Zigbee Alliance announced an industry working group in December 2019 to take the “best of market” technologies from leading smart home standards, portfolios and ecosystems and to develop a “super spec” that will be open, inclusive and a significant industry shift in the smart home market. The Project Connected Home over IP (CHIP) is looking to unify the environment, under one technology, one certification program and one logo. Training Technicians Using Technology Technology is also helping to fill the skills gap in the HVAC market. The XOi Vision platform helps on-site HVAC technicians in three ways. One is to “capture” images and videos. A technician can take a picture (with a smart phone or tablet), and the system’s machine learning can extract the text from the nameplate of a unit in the field, interpret the type of name plate, and provide full model number, serial number and other information about the unit, which is relayed automatically to the technician in a text message. A quick search also provides a manual, wiring diagram and video training content for that specific unit.

As the Internet of Things (IoT) has evolved, the need has become obvious for stronger unity among brands and ecosystems to enable products within smart environments to work together more easily. Working to serve that need is the Zigbee Alliance, which seeks to promote collaboration in the Internet of Things by creating, evolving, and promoting universal open standards that enable all objects to connect and interact. Their effort took off when Amazon, Apple, Google and the Zigbee Alliance announced an industry working group in December 2019 to take the “best of market” technologies from leading smart home standards, portfolios and ecosystems and to develop a “super spec” that will be open, inclusive and a significant industry shift in the smart home market. smart home automation system “Zigbee Alliance has been for a while now working on openness and interoperability, which has led us to the Project Connected Home over IP (CHIP), which is looking to unify the environment, under one technology, one certification program and one logo,” says Chris LaPré, Zigbee Alliance’s IoT Solutions Architect. “It really does fuel IoT possibilities, whether in HVAC or any other sectors.” There is a stronger need for unity, which is why we are developing Project Connected Home over IP" Project CHIP is a royalty-free connectivity standard that unifies brands and ecosystems into a single smart home automation system that operates any other technology based on Internet Protocol (IP). The intent is to simplify product development for device manufacturers, broaden consumer choice, and to ensure easy discoverability, deployment and engagement to fuel connected living. unifies that environment “We have noticed that, as the IoT has evolved, there is a stronger need for unity, which is why we are developing Project Connected Home over IP,” says Jon Harros, Zigbee Alliance’s Director of Certification and Testing Programs. “It fits with the Zigbee Alliance’s goal to unify systems, and to focus on everyone using the same application at the top. It unifies that environment, whether you are integrating your system with Amazon Echo devices or connecting to Google Home.” Participating in development of Project CHIP are 125 companies of various types from around the world working together with more than 1,100 of their experts serving across sub-committees to formulate specifications and fine-tune the project. Although the technology is being developed for the home market, the specifications have been formulated with an eye toward expanding into the commercial market in the future. home system technologies Development of open, interoperable systems provides greater freedom for consumers to choose among the many technology choices on the market, without being tied to a single brand or ecosystem. Zigbee Alliance certifications and memberships span the globe, with roughly a third in Europe, a third in North America and a third in Asia. Involvement in Europe is slightly higher than the other regions. Alliance members represent manufacturing sites all over the world. Project CHIP is a newer initiative of the Zigbee Alliance, which previously developed Zigbee Pro to enable home system technologies to operate using IEEE 802.15.4 wireless signals on the 2.4GHz radio band over a self-healing true mesh network. The original Zigbee protocol is used for many applications around the world, including HVAC. smart temperature devices HVAC developers who have specific use cases should have a look at the work of the alliance Members of the Zigbee Alliance include HVAC companies such as Lennox, Stelpro and Belimo, among others. Carrier is a recent company that has joined the Zigbee Alliance. Smart thermostats, including the popular Ecobee, have used the Zigbee protocol. More than 100 different devices have been certified as thermostats or smart temperature devices.  Harros urges other HVAC companies to become more involved with the Alliance. “We want them to come and have a look to see what we are doing and get involved,” he says. “This is where the work is being done as we unify the environment and bring together all the devices and ecosystems to work together.” HVAC developers who have specific use cases should have a look at the work of the alliance, he adds. certification transfer program Among the strengths of the Zigbee Alliance are years of experience certifying products, which includes testing them and confirming that they comply with the promoted specifications and functionality. The specifications are open standards that are developed in cooperation with all the companies that are Zigbee Alliance members. Another route is the certification transfer program, in which a company chooses a certified white-label product, becomes a member of the Alliance, and then rebrands the product while retaining the certification. “It helps them get products on the market quickly while they build their own knowledge base,” says Harros. "All our work is focused on standardizing the behavior and functionality of products and making sure everyone is following the same standard to get interoperability,” says Harros. “Members all contribute to the standards.”
