Airzone Aidoo Pro Enhances VRF Energy Efficiency

The Olsen Group, based in Boca Raton, Florida, is a national pioneer in HVAC energy optimization. Donald Olsen and his seasoned team of HVAC control specialists have been in business for two decades, integrating energy-saving solutions into over a thousand commercial and large-scale residential projects. In the process, the Olsen Group has become one of North America’s top suppliers of Verdant thermostats. Verdant devices leverage intelligent occupancy sensors and proprietary software to reduce HVAC runtimes by 45 percent on average. HVAC control integration Verdant’s effectiveness, reliability, and broad compatibility have made Verdant the energy management solution of choice for thousands of hotels and MDUs, including multifamily buildings, senior living, and student housing.  The Olsen Group has forged a productive two-way partnership with Verdant. Donald Olsen and his team have made it a priority to share data, customer feedback, and requirements with Verdant – and Verdant, in turn, has come to rely on Olsen when they need to field test a new solution. In May of 2024, Verdant reached out to Olsen for help with a new pilot program aiming to facilitate more effective HVAC control integration, easier service, and deep energy savings for MDU projects around the globe. The Challenge Commercial VRF systems have an extremely attractive set of upsides for hotel operators Inverter (VRF) system design is becoming increasingly common in hospitality settings. Commercial VRF systems have an extremely attractive set of upsides for hotel operators. They are significantly more energy efficient and quieter than traditional VTACs or PTACs; they can provide simultaneous heating and cooling to different zones for optimal guest comfort; and they allow both individual room-level setpoint control and building-level centralized management. However, the majority of VRF units cannot connect directly to a third-party smart thermostat. Because they rely on proprietary manufacturer protocols for variable speed commands and internal diagnostics, VRF units require an external control solution to facilitate bidirectional communication with Verdant thermostats. Installation and commissioning process Every additional component in a system adds complexity and opportunity for human error. In hotels, that complexity is multiplied across hundreds of rooms. “HVAC systems are installed dark for new builds, with no power running to the site,” says Donald Olsen, President and Owner of the Olsen Group. “There’s no way to test as we go. If there are any mistakes during installation, we find out about it when the lights go on after project completion.” And mistakes are nearly inevitable. Some third-party controllers have prominent dipswitches that can be easily snagged or tripped during transportation or installation, altering their configuration and causing them to fail once the system is powered. These switches are often accidentally tripped multiple times throughout the installation and commissioning process, pioneering to a never-ending cycle of errors and service calls. VRF control solutions  Adding to the issue, not all third-party control keys have the ability to retrieve and solve system error codes “Once properly configured and installed, VRF control solutions tend to be incredibly reliable,” says Olsen. “Getting them there is a real challenge, however. Accidents, human error, and repeated recalibrations can drive serious project overruns and client dissatisfaction.” Adding to the problem, not all third-party control solutions have the capability to retrieve and translate system error codes. “If the central management system isn’t getting certified manufacturer control signals from the control device, it may no longer recognize the thermostat. The system will continue to function, but it will always show up in the central manager with an error message,” warns Olsen. Airzone Aidoo Pro control solution These false error reports degrade the overall utility of the central management system, robbing operators of the ability to detect and mitigate problems proactively and requiring onsite testing to diagnose any issues. As VRF systems become the norm for hospitality projects, Verdant needed a solution to reduce the possibility of accidental misconfiguration and improve visibility into system functionality. They called on Olsen to conduct a pilot program, retrofitting sixteen VRF units in the Jacksonville Beach, FL Springhill Suites with the Airzone Aidoo Pro control solution. The Solution For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller The Jacksonville Beach Springhill Suites is a 156-room hotel with a state-of-the-art Daikin VRV rooftop chiller system. The Airzone Aidoo Pro ships preconfigured for the specific HVAC unit model, reducing the possibility for errors during initial installation. For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller. This 1:1 system design simplifies operations and troubleshooting: Any issue can be immediately traced back to a single unit, minimizing the scope and duration or repair downtime. “The Airzone Aidoo Pro offered two key upgrades as a VRV control solution,” says Olsen. “First, the dipswitches are recessed, making them much harder to trip accidentally. Second, Aidoo makes the system much easier to service. We can read error codes, run tests, and diagnose issues remotely, without ever needing to disrupt a guest’s stay.” Airzone’s expansive library This advanced remote management is enabled by Airzone’s expansive library of manufacturer protocols. “Because of our close relationship with HVAC manufacturers, Aidoo Pro can provide the proprietary control signals the central management system is expecting to see,” says Borja Fernandez, Director of OEM Solutions, Airzone. “That preserves all the features of the HVAC unit and thermostat, while also eliminating persistent false error codes. With Aidoo Pro, the central management system can function as a single-pane-of-glass HVAC monitoring and control solution for the building, as intended.” Results and Next Steps The pilot program is expanding to new builds around the globe, including projects in the UK Olsen reports that Springhill Suites is happy with their upgraded VRV system. “They have more visibility into the system and fewer services calls,” says Olsen. “When there is an issue, we can diagnose it remotely for faster resolution and less guest room downtime. It’s a much better customer experience overall.” Verdant is encouraged as well. This pilot program is expanding to several new builds around the globe, including projects in Central America, the Caribbean, the UK, and the EU. HVAC energy savings “There is a massive untapped market for energy-efficient HVAC upgrades in the Caribbean region,” says Olsen. “Energy costs there can exceed a dollar per kilowatt hour. Cost-effective devices like Verdant thermostats and the Airzone Aidoo Pro pay for themselves very easily in that scenario.” Verdant and the Olsen Group have built global brands by helping commercial properties realize significant HVAC energy savings. Through the Airzone Aidoo Pro pilot program, they are continuing to innovate, enabling reliable integration and enterprise-grade control on highly efficient VRF units. “The demand for commercial VRF control is definitely there,” says Olsen. “With Verdant and Airzone, we can deliver it with ease.”

Energetic AHR 2024 Highlights Innovation In The Face Of Regulation

AHR Expo 2024 was abuzz with activity, befitting a dynamic industry in the throes of change.  Industry developments such as electrification and the refrigerant transition render business opportunities on the AHR Expo show floor, where exhibitors display a determination to meet the challenges and thrive in the process. Walking from booth to booth during the three-day show in Chicago, I saw the best the HVAC industry has to offer, up close and personal. Innovation and adaptability are the watchwords as the industry journeys into 2024 and beyond. Refrigerant Transition Top of Mind  Patented R-454B refrigerant enables a simpler transition without redesigning equipment The technology transition is well underway for OEMs seeking to meet a pending AIM Act deadline at the end of the year. OEMs are choosing to embrace either R-32 or R454-B refrigerant to replace legacy R-410A, which is being phased out. Patented R-454B refrigerant enables a simpler transition without redesigning equipment, while R-32 offers advantages such as higher capacity, higher efficiency, and easier cradle-to-cradle management. Arkema Arkema is the only producer of R-32 refrigerant in the United States. The newer refrigerant is being embraced as HVAC OEMs seek to meet the deadline of Jan. 1, 2025, to use lower-GWP (global warming potential) refrigerants in their products. The technology transition is just part of the AIM Act implementation that will also limit allocation and require refrigerant management. Chemours Chemours is a manufacturer of R-454A, R-454B, and R-454C refrigerants. At AHR, they presented hourly education sessions on a variety of subjects. The refrigerant transition will impact everyone in the industry, including refrigerant producers, equipment manufacturers, contractors, and end users. R-454B refrigerant provides identical performance in HVAC systems compared to the previous refrigerant (R-410A). There is less need to redesign equipment; just adding sensors for leak mitigation can address the mild flammability of A2L refrigerants. Because of the 2025 deadline, 2024 will be the “year of new products” in the HVAC market. OEMs pioneering Innovation  Carrier and others are offering smaller footprints, seeking to meet environmental targets Innovation in the HVAC market is led by companies such as Carrier, which has introduced 100 new products each year for the past eight years.

The Blind Spot Of Modern Smart Thermostats

Using air conditioners and electric fans to stay cool accounts for nearly 20% of the total electricity used in buildings around the world, according to a report from the International Energy Agency. hybrid work model As a unique mix of key factors, such as the adoption of the hybrid work model and escalating heatwaves in certain regions of the United States keep people indoors for longer periods, this 20% share represents an increasingly costly line item on household budgets. Those within the market are responding by seeking out products that can help them control climates more efficiently. Smart thermostats and inverters Markets for smart thermostats and inverter HVAC controllers are clear illustrations of in-demand technology Given what the industry is experiencing, the markets for smart thermostats and inverter HVAC controllers, which are clear illustrations of in-demand technology, are experiencing growth. But as they do, are the technologies growing together or growing apart? Rapid Growth in Both Markets  Discounts and incentives The smart thermostat market has expanded steadily in recent years, with that growth projected to continue through the 2020s in part due to savings of up to 8% on energy bills homeowners can recoup with the best smart thermostats. The sleek design and digital interface of modern smart thermostats, coupled with the increased control capabilities provided by mobile applications, seem to offer homeowners unprecedented control over their indoor climate. Moreover, the growing popularity of rebate programs providing discounts and incentives is making these solutions even more attractive. Real-time heating/cooling needs with Inverter/VRF Inverter/VRF HVAC systems are capable of adjusting the frequency of the compressor precisely Concurrently, the market for Inverter/VRF HVAC control systems is also expanding. It is estimated that the global Inverter/VRF market will grow from USD $17.6 billion (2020) to $31.9 billion (2025) at a CAGR of 12.7%, with the US identified as the fastest-growing Inverter/VRF market. Unlike their single-speed system counterparts which operate on an on/off or all-or-nothing dichotomy, Inverter/VRF HVAC systems are capable of adjusting the frequency of the compressor to precisely match the real-time heating/cooling needs of an environment. By regulating the fan speed and airflow, Inverter/VRF systems are extremely efficient at keeping an environment at a precisely set temperature.  Enhanced HVAC system performance or not? Given the rapidly expanding markets, one might think that the easy interface of the current smartest thermostats and the operational efficiency of the best Inverter/VRF HVAC controllers could combine to create an exceptionally comfortable and cost-efficient experience for homeowners, and an easily interoperable install for HVAC pros. However, the question remains: have these devices genuinely enhanced HVAC system performance in terms of accuracy, consistency, and efficiency? More importantly, have they made living spaces more comfortable? Have these growing markets and technological advancements made life easier for industry pros?  Persistent and pervasive incompatibility This communication breakdown leads to issues such as set temperature variance, inefficient operation Many are surprised to discover that the response to these important queries is frequently negative and “no”, due to a persistent and pervasive incompatibility between smart thermostats and Inverter/ VRF HVAC controllers. It is this incompatibility that ultimately negates the advanced features and intelligence of each product. This communication breakdown leads to issues such as set temperature variance, inefficient operation, and energy consumption.  Confronting the Critical Interoperability Challenges Ideally, the current smart thermostats, and the benefits they bring such as user-friendly interfaces, would integrate flawlessly with high-efficiency Inverter/VRF HVAC systems, enhancing comfort and cost-efficiency while simplifying installation for HVAC professionals. Unfortunately, this ideal scenario is elusive. The core problem stems from these technologies developing and evolving separately, and in isolated environments. Inadequate two-way communication While individual support for certain protocols may exist, they fail to communicate complex instructions effectively While individual support for certain protocols may exist, they fail to communicate complex instructions effectively due to inadequate two-way communication. When a smart thermostat is improperly paired with an intelligent Inverter/VRF HVAC system, the resulting communication breakdown forces the HVAC system to revert back to single-speed operations, completely undermining its full potential, and sophisticated features. Inefficiency and discomfort Given its prevalence, what does this incompatibility mean for HVAC professionals and their clients? Consider a scenario where a user desires to adjust the indoor temperature to 68°F via a smart thermostat. Since the Inverter/VRF unit can only be adjusted by means of its own communication protocol, and the output of the smart thermostat is a dry contact closure, the 68°F would never be properly relayed to the air conditioner. In other words, the smart thermostat does not provide information on how hard the system is working or the deviation of the current temperature from the desired set point. As a result, the system cannot modulate its output to precisely match the temperature needs of an environment, and the air handling unit within the system is forced to always operate at high speeds creating inefficiency and discomfort.  On-and-off mode Homeowners miss out on the benefits of their investment, and installers find themselves in the predicament Moreover, this style of operation is quite noisy, as the HVAC system drones on at full capacity every time it is reactivated. This on-and-off mode of operation consumes more energy, comparable to stop-and-start gas-guzzling city driving versus smooth highway cruising. Both homeowners and installers bear the brunt of these drawbacks, homeowners miss out on the benefits of their investment, and installers find themselves in the predicament of either explaining this intricate issue or spending valuable time troubleshooting. What Can Be Done to Address Incompatibility?  While this convergence of technology and home comfort presents significant potential and profound challenges, this situation is not without a solution. The industry’s most advanced smart thermostats and efficient Inverter/VRF HVAC controllers both possess impressive capabilities, but the key to success lies in improving their ability to fluently exchange commands and information.  Translator between smart thermostat and Inverter/VRF These remarkable devices contain the unit's protocols, deftly translating the commands of the smart thermostat Thankfully, there are solutions within the market from industry pioneers that act as a "translator" between the smart thermostat and the Inverter/VRF unit. These remarkable devices contain the unit's protocols, deftly translating the commands of the smart thermostat, creating a seamless conduit of communication. Enhancing interoperability Enhancing interoperability is a prevailing trend across the smart home sector, and it is imperative the HVAC industry works to align with this trend. By embracing such changes, HVAC professionals can offer unparalleled value and functionality to their clients while simultaneously reducing installation complexities. This paradigm shift offers a unique opportunity to alleviate their challenges while providing customers with extraordinary value and performance from their HVAC systems.
