Thanks to breakthroughs in Internet-of-Things technology, facilities managers can monitor boiler equipment operation from virtually anywhere. Picture a typical boiler installation at a large facility like a hospital or university. Manually monitoring a system like that could involve many operators spread over several buildings, each responsible for checking system consoles and monitors. Tracking down a failure might take hours—and that’s after they find out there IS a failure. Troubleshooting these systems can be difficult, time consuming, and labor-intensive. Preferred Cloud Platform To help solve that problem, Preferred Utilities Manufacturing offers a state-of-the-art, secure technology called the Preferred Cloud Platform for remote equipment monitoring. This platform utilizes customized, pre-built analytics to instantly give customers the most actionable data for operating efficiency. Boiler room operators and facility managers can receive equipment information anywhere they are Cloud-based monitoring allows the operators of these systems to observe consoles remotely and receive alerts and updates via their mobile devices or computers. These systems are simple to install, they operate over a secure private network, and they gather and present the data in an easy to understand user interface. The boiler room operators and facility managers can receive equipment information anywhere they are connected to the web, and automated alerts allow them to be the first to know, in real time, when a boiler or other equipment needs attention. Communications Are Secure And Encrypted Security is a concern for any system that is monitored via the cloud. The Preferred Cloud Platform ensures that all communications are secure and encrypted, with both sending and receiving parties validated before data is shared. The gateway is connected via an isolated, private network, and ongoing updates keep the platform secure and up to date. Remote monitoring is especially valuable for critical facilities like hospitals and data centers. They must operate around-the-clock, but paying for 24-hour maintenance staff is a major expense. With remote monitoring, an on-call maintenance staff is sufficient. It also frees up employees to handle different tasks while remaining available to respond to malfunctions if they happen. Remote Monitoring A problem can sometimes be solved before anyone is even aware the interruption has occurredThe kind of “head start” offered by remote monitoring is particularly valuable in extremely cold or hot weather, when temperatures in buildings can change quickly. Before remote monitoring, the first time a maintenance team would hear about a problem was often from an angry tenant who was already too cold or too hot. Finding out about a problem via the cloud allows for troubleshooting to begin immediately, which means a problem can sometimes be solved before anyone is even aware the interruption has occurred. Maintenance Staffers “Cloud-based monitors work around the clock, seven days a week, 365 days a year,” said David Bohn, President and CEO of Preferred Utilities. “Critical maintenance staffers are free to enjoy their weekends and holidays, but in the event of an emergency, they can get an alert and still have enough time to address the situation. “And our platform provides a high level of detail, so the person receiving the alert can make decisions about what action is necessary right on the spot.” The Preferred Cloud Platform is available for installation, and it can often be installed in a single day.

There was plenty to see and appreciate at AHR Expo in Orlando. And there is good news to report: Innovation is alive and well in the HVAC market. Some new products on display demonstrated genuine ingenuity. Exhibitors had enthusiasm to spare as they shared what’s new in the market with this first-time visitor to the show. HVAC is not a new market, but it is changing and, in some regards, re-inventing itself. The vibrancy, variety and sheer size of AHR Expo showed off the newest and best the industry has to offer. ‘Better Way to Heat and Cool’ Electronics highlighted the benefits of inverter systems -- "a better way to heat and cool" -- at their press event at AHR Expo. Despite the advantages, HVAC contractors are pushing back at the new, less familiar systems. The industry is at a "crossroads." Inverter systems have variable-frequency drives that control the speed of the compressor motor, enabling lower power consumption – operating at a partial load as Innovation is alive and well in the HVAC marketLG opposed to a full load. For example, an inverter system may use only 20 amps compared to 90 amps for traditional systems. The systems are quieter, too. There are also now inverter systems for ducted systems – "the space in between that nobody is talking about". New "hydro kits" can also extend the benefits of the systems, providing radiant floor heat or the ability to melt snow from a driveway. LG Electronics also introduced a new line of IP-based controls, aimed at the 97% of commercial buildings that are 100,000 square feet or less, many of which don't have building automation systems. The controller can be used in lieu of integrating with third party systems, which can add costs. They also are introducing predictive analytics that can consider multiple conditions over time and then predict things that may happen, such as maintenance requirements. The company also emphasized the benefit of LG as part of a range of products the company provides for the home, from OLED televisions to appliances to robotic vacuum cleaners. There is an opportunity for all the devices to be connected to an LG panel and "drive the experience." Monitoring Indoor Air Quality Airthings was a new exhibitor at AHR Expo, located off the beaten path among the high-numbered booths. Even so, the company had a great show with “enormous interest,” said Oyvind Birkenes, CEO. Airthings has an indoor air quality monitoring system, with a battery-operated, wireless sensor as the main component. There Some new products on display demonstrated genuine ingenuityare actually seven sensors inside the device, monitoring radon gas, CO2 level, temperature, humidity, VOC levels, pressure and ambient light. The device can be easily mounted on the wall and provides data every 5 minutes, which is sent to the cloud to be analyzed. The cloud system provides an overview of data, which is customizable. Users can set notification levels and/or download air quality reports. The system can also be integrated with building management systems (BMS) or other dashboard displays. A hub can manage up to 50 of the sensors for larger systems, in effect, a fully independent local network. Birkenes said the device provides a “disruptive” upsell opportunity for various platforms. Cooling Towers Making a Comeback A new era of cooling towers includes products that are modular and built on a smaller scale for tighter locations, says Neal Walsh, HVAC Business Manager, Baltimore Aircoil Company. “We’re turning the concept of cooling towers on its head,” said Walsh. The new concept leverages the energy efficiency advantages of cooling towers, while opening new applications to the technology. The modules of the product can be put in place by a forklift, and it is less than half the size of a traditional cooling tower. Up to six of the devices can be installed in A new era of cooling towers includes products that are modular and built on a smaller scale for tighter locationsa row with a control panel. Low water usage enables the system to be flushed and refilled once a day – no expensive water treatment needed. In all, it is less expensive to install and maintain, and could be installed inside a building, on a roof or anywhere there is space. The product is popular with school districts, which seek to avoid refrigerants. The new design is driving a “resurgence in popularity” in the market, said Walsh. Plastic Pipes with Easy Waterproof Sealing Uponor displayed pipe systems made of PEXA (cross-linked polyethylene) plastic, featuring “crosslinking thermal memory.” The pipe returns to its original shape when heated. It is available in ½-in. to 4-in diameters for residential or commercial installations. A special tool can be used to expand the pipe to accept a fitting, and then the pipe returns to its original shape when heated to create a water-tight seal without glue or solvents. The pipes can be used for radiant heating applications, and Uponor offers “roll-out” mats (pre-assembled configurations of pipes) for easy installation. Through a partnership with a Serbian company, the company also now offers polypropylene pipe for larger applications. There was plenty to see and appreciate at AHR Expo in Orlando SPVU Systems with Greater Efficiency Bard offers “single-package vertical units” for commercial applications in space-confined systems, whether the application is equipment cooling or “creature Many products demonstrated at AHR are also big in the education marketcomfort,” said Paul Quigley, Senior Vice President, Sales and Marketing. The factory-sealed systems ensure greater durability for mission-critical applications, such as telecommunications, data centers, etc. Bard’s products are also big in the education market (especially portable classrooms). Their line has been completely redesigned and reconfigured by Bard’s engineers; they have replaced nine major product families (and 10 million product iterations) with just two categories. The new models meet the Department of Energy’s 11EER minimum energy conservation standards for Single Package Vertical Unit (SPVU) air conditioners and heat pumps – a 22 percent increase in efficiency. They can also remove 35% more humidity than other units. The new systems use recycled denim for insulation (instead of fiberglass). Leveraging the Benefits of UV-C UV Resources highlighted the use of UV-C spectrum light for HVAC applications. They have a germicidal lamp system that uses UV-C to penetrate the HVAC coil to eliminate microbial buildup. It keeps coil surfaces, drain pans, air filters and ducts free of organic buildup and works better than pressure washing or chemical treatment. The company also displayed a germicidal UV fixture that can be wall-mounted at 7 feet or higher in a room. Special louvers direct “germicidal irradiation” at an upward and outward angle and create a zone of UV-C to kill germs and minimizes the dosage in the lower area of the room. It's useful in doctors’ offices, public buildings, etc. LG Components’ New Compressor LG Components launched a new product – a fusion compressor (hybrid) that merges the best of rotary systems and of scroll technology. Durability-improving innovations include a more sensitive vacuum prevention device and a stronger, stress-tested discharge reed valve that withstands the harsh operating conditions posed by refrigeration applications and limits excessive sound levels. It is compatible with multiple refrigerants, including R-404A, R-507, R-407A, R-407C, R-448A and R-449A; the compressor has a capacity range of 1-6 HP Catch up on our Day One Review here. or our Day Two Review here.
Technologies such as machine learning and the internet of things (IoT) are taking their place alongside more traditional products at AHR Expo in Orlando this week. Performance of the industry’s historic product mix continues to improve from the standpoint of efficiency and sustainability, and elements of the industry’s “digitization” are making it even better. The “smart building” has finally arrived in earnest. “Our world is changing,” said Jenny Stentz, Area Vice President, Building Solutions, North America, for Johnson Controls. “Our customers are talking about it everywhere we go. They are demanding more control over the environment they occupy, and that is driving change.” Collaborating With Customers For Efficient Solutions In the case of Johnson Controls, the changes are being implemented in the context of a collaborative relationship with customers; in effect, they are working Changes are being implemented in the context of a collaborative relationship with customerstogether with customers in the co-development of solutions that deploy the latest technologies. The massive amount of data available from today’s systems, when analyzed using new artificial intelligence (AI) and machine learning tools, yields opportunities for more efficient systems for customers. Johnson Controls offered a panel discussion on “Changing Customer Demands” to kick off the AHR Expo. The deployment of “digital assets” alongside JCI’s product mix can have a practical impact on energy usage, saving in the range of 20 to 40% of the costs of operating a system, says the company. “Together, they drive the outcomes our customers are looking for,” said George Oliver, Johnson Controls’ Chairman and Chief Executive Officer. Oliver added: “We try to put the customer at the center of all that we do. We try to understand the questions and be ahead of the curve.” Pushing The Digital Message JCI is continuing to invest to improve its product mix — in the range of $650 to $700 million in the last year. Investments include development of a state-of-the-art facility in Norman, Okla. There is also a training center, and the company continues to invest in the Navigator platform. “We have truly focused on being a products company, which really focuses our investment,” said Mike Ellis, Executive Vice President, Chief Customer and Digital Officer, Johnson Controls. “It all depends on our ability to leverage what is right in front of us.” JCI positions itself as a “pure-play” buildings company that is IoT-aware. There were other companies pushing a digital message on the first day of AHR Expo, too. For example, Delta showcased a comprehensive suite of building automation technologies built around the theme “Smarter Buildings, Smarter Cities.” Their booth showcased the ability to improve operating efficiency and reduce energy usage by combining various Delta products, including building automation solutions from Delta Controls Inc. and LOYTEC. Panasonic highlighted new technologies, including a system that suppresses pollutants and odors using nano-sized electrostatic atomized water particles. Delta’s O3 Sensor Hub combines multiple temperature and occupancy inputs with audio and detection accuracy enhanced by machine learning to provide more precise temperature reading and better control of other systems. Digital-era Machine Learning Armstrong Fluid Technology highlighted Active Performance Management based on digital-era machine learning. The system optimizes the operation of equipment and makes recommendations about how operators can make the equipment work even better. The system operates on three levels. First, the Design Envelope intelligent devices (such as pumps and booster systems) send alerts and warnings about operation. Second, a systems optimization level considers data from a number of devices together; third, all the data is brought up into the cloud. The suite of solutions ensures that equipment runs at optimal condition. It prevents performance drift; furthermore, from population learning, the system improves the performance of a building over time. The system continues to learn by analyzing data from the population of assets connected to the cloud, including the large installed base of Design Envelope products. Exciting New Product Innovations Panasonic is highlighting the ClimaPure XE wall-mounted heat pump for cold climates. The ductless system features “nanoeX,” a built-in air and surface purification There were many companies pushing a digital message on the first day of AHR Expotechnology that reduces pollutants and odors. Nano-sized electrostatic atomized water particles are rich in hydroxyl (OH) radicals, which are effective at suppressing pollutants and odors. Friedrich highlighted the VRP Variable Refrigerant Packaged Heat Pumps, which provide VRF performance with single package simplicity. The “VRF in a box” solves more design problems than complex systems like VRF and 4-pipe systems. The product offers best-in-class cooling performance, super-efficient heating, true humidity control, and conditioned fresh air to help building owners achieve ASHRAE 62.1 compliance for commercial buildings and 62.2 compliance for residential buildings. Bradford White is showing the AeroTherm Series Heat Pump Water Heater that provides hot water more efficiently using technology to transfer heat from the air into the tank. The yearly energy savings is around $304 versus an electric tank. The pump can quickly pay for itself. Read our review of Day Two of the show here.
Smart homes are a key focus at CES 2020, the world’s largest technology event, January 7-10 in Las Vegas. The giant show features more than 170,000 attendees, 4,500 exhibitors and 1,100 industry thought-leaders featured on the CES stage. A range of technologies will be on display, from artificial intelligence (AI) to 5G, vehicle technology to AR/VR (augmented and virtual reality), robotics to home automation. smart home environment The role of intelligent HVAC systems in the smart home will be featured at the show, and the impact of the Internet of Things (IoT) on HVAC systems (among other technologies) will be prominent. HVAC is an element that provides measurable value in the smart home environment. The Nest intelligent thermostat is almost a decade old. In the years since its introduction, HVAC has become even more intrinsically integrated into the intelligent home. “Market players are looking to expand beyond established smart home devices like smart thermostats and networked cameras to products like smart water leak detectors, smart pet feeders, and smart air purifiers,” says Elizabeth Parks, President, Parks Associates. Electronic door lock approach The Resideo T-Series smart thermostats support wireless Smart Room Sensors “For the smart home market at CES this year, we expect to see numerous announcements regarding home awareness,” says Blake Kozak, Senior Principal Analyst at IHS Markit. “The impact of this [event] for the smart home could be about delivering home analytics and enhancing privacy through cloudless architectures and new electronic door lock approaches,” he adds. An example of home analytics is the Resideo Home app, introduced in December, which will make whole-home monitoring possible for four critical networks of the home – water, air, energy and security. Resideo promises a “simplified and integrated smart home experience.” The Resideo T-Series smart thermostats support wireless Smart Room Sensors to balance and prioritize temperatures in the home. air management controller Daikin North America will be showing the Daikin One+ smart thermostat, an intelligent home air management controller. Beyond a typical smart thermostat, it is a controller for a full professional HVAC system with a growing ecosystem of air quality modules to give consumers more control over the air they breathe and a premium HVAC experience. OxiCool is launching HomeCool, a clean and resilient AC technology. It is designed to provide clean and silent air-conditioning for the home. The product can be configured to operate off solar thermal, natural gas, propane or electricity. It uses no harmful refrigerant and only four natural elements—earth, water, fire and air. The clean technology uses molecular sieves in vacuum-sealed units made from stainless steel and uses zero GWP water as its refrigerant. unified solution to consumers “Consumers who already own smart home products are buying more devices,” says Parks. “A key issue to address though is the lack of purchases occurring with the non-owners of these devices. Despite purchase intentions being high, consumers are not making the purchase to move adoption of products. After 10 years of being in the market, smart thermostats still only have about 11-13% adoption rate in the U.S." "In 2020, we will see companies working to provide a unified solution to consumers through professional installation and also continue to see the single-point solution pushed to get consumers in the door with a single product and expand from there.”
When Pine Valley Ranch, a Spencerville, Ohio-based egg-breaking facility was looking for an energy efficient way to wash 600 cases of eggs an hour they turned to Consolidated Hunter, a local heating contractor, and Pickrel Brothers, a provider of industrial heating supplies to help present options. Their recommendation? Install six Weil-McLain SlimFit 750 commercial high-efficiency hot water boilers. “We’re an egg-breaking plant,” explains Evan Fleck, an owner of Pine Valley Ranch. “Our eggs come straight from the barn and are immediately washed. Then they are broken, separated and chilled. Once this is done, they are loaded into liquid tankers and shipped to be pasteurized. Every step of the process is important, especially the washing of the eggs. We need plenty of hot water for that, as well as for other daily operations.” Efficient production process The 4.5 million BTU/hour Pine Valley heating system supports seven individual heating zones The 4.5 million BTU/hour Pine Valley heating system supports seven individual heating zones. The first three zones are dedicated to the egg washing machines and supported with 750 BTU/hour boilers. The fourth and fifth zones support the clean-in-place equipment (990,000 BTU/hour heat exchangers) while the two remaining zones are for the indirect fired water heater and the on-site plant mixing station. “Every zone is critical to ensuring a high-quality, efficient production process,” says Fleck. “We have more than 900,000 chickens at this facility and they produce a lot of eggs. The Weil-McLain boiler systems provides a consistent source of hot water to accommodate this large number.” Wide range of commercial installations SlimFit boilers have been serving the heating industry since 2009 with rugged, cast horizontal heat exchanger sections that provide thermal efficiencies up to 95.8% (SlimFit 1000 & 1500 models). The boilers feature a low pressure drop design, with large water passageways to accommodate a wide range of commercial installations, including retrofit and replacement applications with older water systems. Other standard features include a composite condensate tray for heat exchanger longevity The larger SlimFit 1000-2000 models feature a narrow ‘door-fit’ profile and integrated roller casters for improved installation maneuverability in confined spaces and weight restricted areas, saving contractors time and money. Other standard features include a composite condensate tray for heat exchanger longevity, customizable control mounting location (front or side) and leveling legs, which mitigate the need for a concrete service pad. Typical heating operation conditions Control features include a setup wizard that guides the installer through the start-up process and 10 preset typical heating operation conditions. The SlimFit also features zone stacking up to 24 programmable zones without the need for additional external panels and 0-10 VDC analog output signal for easy integration with a lag boiler in a hybrid system. “We really appreciate how the Weil-McLain boiler-system enhances our operation,” says Fleck. “The equipment was installed when the facility was built so they’ve been part of our production process from the beginning. Running a plant of this size always presents challenges, but our hot water needs are not one of them.”
Fort Worth's historic downtown art-deco Sinclair building, now a Marriott Autograph Collection hotel, boasts its new variable refrigerant flow (VRF) HVAC system which raised the first-floor ceilings and cleared the roof for a new bar. Baird, Hampton & Brown (BHB) provided civil, electrical, and mechanical/plumbing engineering design services to make the building one of the most technologically advanced hotels in the world. Variable refrigerant flow (VRF) system As part of the renovation, BHB's mechanical engineers were tasked with replacing the building's traditional hydronic heating and cooling system with the increasingly popular variable refrigerant flow (VRF). VRF is a type of air-conditioning system that adjusts refrigerant flow to different areas of a building as needed, instead of distributing large quantities of refrigerant at all times. This technique creates practical zoning, giving occupants the ability to adjust their space temperature to their preferred comfort level. An added advantage is that VRF is one of the most sustainable systems on the market. "The VRF system helps The Sinclair be a more efficient and smarter building. A hotel room's AC unit will respond to the person who walks in and automatically know what set-point temperature they are looking for," stated Gibran Michel, BHB Associate and Senior Mechanical Designer. VRF outdoor units BHB's design of the hotel's VRF system was the firm's largest to date. Since VRF does not require as much ductwork and space as a traditional HVAC system, the team was able to raise the ceiling heights and bring in ornate windows on the lobby level. In addition, the VRF outdoor units were placed in the alleyway instead of the roof, which made room for a rooftop bar. The Sinclair held its grand opening in January 2020 and now offers a unique and modern experience while maintaining its stylish look and feel, thanks in part to its advanced VRF HVAC system.
A construction project in Calgary, Canada, called Cube, features several firsts. It’s the city’s first office-to-residential space conversion and real estate developer Strategic Group’s first re-purposing project. It’s also the first building in Canada to feature the latest advancement in condensing boiler heating technology from Weil-McLain. The Cube – a 52,000 square-foot, seven-story building in Calgary’s Beltline neighborhood –features 65 one and two bedroom residential rental units and is just a short walk from the city’s downtown area. Once the aging Stephenson office building, the 38-year-old building was converted to new residential and rental units in 2019. Latest Boiler Technology Cities like Calgary have seen office building vacancy rates as high as 27% in the past few years" The building’s developer, Ash Mahmoud, Managing Director of Calgary-based Strategic Builders Inc (SBI), the construction arm of Strategic Group, which owns, manages and develops office, retail and apartment properties across Canada, oversaw the conversion project. “Cities like Calgary have seen office building vacancy rates as high as 27% in the past few years,” said Mahmoud. “Rather than let downtown buildings go unused, it has been one of our core missions to convert them into residential.” In addition to incorporating contemporary designs and styling finishes, Mahmoud also sought the latest in boiler technology to heat the new development. High Efficiency Boiler System To conduct the HVAC overhaul, Mahmoud turned to Nu-Mun Contracting, a Calgary-based HVAC company offering commercial and residential plumbing, heating, and air-conditioning services. Working with SBI and the project engineer, David Muncaster, owner of Nu-Mun Contracting, devised a strategy to convert the building to a high efficiency boiler system and recommended specification of the latest advancement in condensing boiler technology: the Stainless Vertical Firetube (SVF) from Weil-McLain. Eric Cameron, project manager with Nu-Mun Contracting, oversaw the boiler installation at the building. “We have a long standing relationship with Weil-McLain, and we trust the quality of their boilers,” said Cameron. “The SVF boilers were the perfect match for the space.” Simplify Installation And Operation The SVF also meets all market-driven bid specifications, and is designed for most heating needsTo meet the building’s heating style and load, the team installed two SVF 1100 MBH high-efficiency condensing gas boilers in the building. The SVF boilers features thermal efficiencies up to 97.1%, a clover-shaped stainless steel fire tube heat exchanger for corrosion resistance, and the intuitive and user-friendly Unity™ control system to simplify installation and operation. “With superior thermal efficiencies, the SVF line offers cost savings and energy efficiencies that could allow owners to qualify for local utility rebates, if available,” said Craig Demaray, National Sales Manager with Weil-McLain Canada. “The SVF also meets all market-driven bid specifications, and is designed for most heating needs including applications in schools and other educational facilities, public institutions, healthcare buildings, offices, hotels, multi-family, churches and more.” Multiple Boiler System The high-water content design of SVF heat exchanger means a low loss header is not required providing cost savings so the boilers can simply be piped in a primary-secondary design. The on-board Unity™ control system allowed the boilers to communicate with each other in a Multiple Boiler System (MBS). A master boiler controls the modulation and sequencing of the boilers on the network In this configuration, a master boiler controls the modulation and sequencing of the boilers on the network to achieve the desired system supply temperature. “With the automatic sequencing feature, the boilers communicate directly with one another so they sequence themselves and rotate as needed,” said Cameron. “They operate to optimize energy use and efficiencies. When heat is required, the boilers will stage on as needed.” Time-Saving Installation The Cube conversion project was completed in 12 months and more than two-thirds of the building is already leased to residents. Mahmoud praised the experience with Nu-Mun Contracting. “Working together with Nu-Mun was a seamless operation,” said Mahmoud. “It was a really great relationship and, as a result, the job was a complete success.” The start-up and installation progressed smoothly in part due to the way these boilers are designed" “The start-up and installation progressed smoothly in part due to the way these boilers are designed,” said Cameron. “The SVF boilers offers time-saving installation features that include heavy-duty roller casters for improved maneuverability in confined spaces, industrial-grade leveling legs, and an end-shot burner design requiring only 18 inches overhead space.” Low Operating Costs Mahmoud appreciates the ease of maintenance that the boilers offer for the building staff “The boilers are really user friendly,” said Mahmoud. “We can even conduct the annual maintenance on the units ourselves to keep them in tip-top shape.” In addition to offering class leading serviceability, the new boilers also offer low operating costs and are expected to bring energy savings and a reduction in gas usage to the facility. But most important, Mahmoud reported that tenants are extremely pleased with the climate and comfort of the building.
