Breaking HVAC News: EPA Grants One-Year Extension for VRF Systems Using High-GWP HFCsHey everyone, Tony Mormino here with some important news for the HVAC community.The Environmental Protection Agency (EPA) has proposed a rule that could significantly impact our industry. This new rule, titled “Phasedown of Hydrofluorocarbons: Restrictions on the Use of HFCs under the AIM Act in the Variable Refrigerant Flow (VRF) Air Conditioning Subsector,” offers a crucial extension for the installation of new VRF systems using high-GWP HFCs (with a GWP of 700 or more).Here’s the deal: The EPA’s proposed rule would grant an additional year, extending the deadline to January 1, 2027. This extension is only applicable if the VRF components were manufactured in the U.S. or imported before January 1, 2026. This move is designed to address concerns about unsold inventory and help our industry transition more smoothly to environmentally friendly alternatives.This development is significant for all of us working with VRF systems. It gives us more time to adjust and ensures that we’re not left with stranded assets due to regulatory changes. I’ll be keeping a close eye on this proposal and its potential impacts on our work. Stay tuned for more updates as we navigate these changes together.Thanks for reading, and let’s keep pushing forward!Best,Tony

Hey there! Just a little reminder about the importance of staying in your lane. It's like when a plumber sticks to plumbing and not HVAC work. Sticking to what you know best helps you work more efficiently and with greater expertise. This leads to fewer mistakes and higher productivity. Plus, it helps to build your brand and customer loyalty. When you really focus on what you do best, you'll use your resources more effectively and avoid unnecessary costs and risks.In other words, "The riches are in the niches."

Understanding HVLS Fans and Their ApplicationsWhat is an HVLS Fan?High-Volume, Low-Speed (HVLS) fans are large industrial fans designed to move a significant amount of air at low rotational speeds. Typically, HVLS fans have diameters ranging from 7 feet to 24 feet and operate at slow speeds to create a gentle, yet highly effective airflow. These fans are typically ceiling-mounted and are used in a variety of commercial and industrial settings.Key Features of HVLS Fans:1.Size and Design: HVLS fans are large, with blades designed to move air efficiently. Their size allows them to circulate a substantial volume of air over a wide area.2.Energy Efficiency: They use less energy compared to traditional high-speed fans because they operate at lower speeds while still providing effective air movement.3.Quiet Operation: Due to their low-speed operation, HVLS fans generate less noise, making them suitable for environments where noise reduction is important.4.Comfort and Air Quality: By moving large volumes of air, HVLS fans help to maintain consistent temperatures and improve air quality, reducing the perceived temperature and helping to control humidity levels.When to Use HVLS Fans:1.Large Spaces: HVLS fans are ideal for large open areas such as warehouses, factories, gymnasiums, agricultural facilities, and hangars. Their wide coverage reduces the need for multiple smaller fans, simplifying installation and maintenance.2.Energy Savings: In facilities looking to reduce heating and cooling costs, HVLS fans can be integrated with HVAC systems to distribute conditioned air more evenly, reducing the load on the system.3.Employee Comfort: In workspaces where maintaining a comfortable environment is crucial for productivity and safety, HVLS fans provide a consistent airflow that can help regulate temperature and improve worker comfort.4.Humidity Control: HVLS fans are effective in assisting HVAC systems in managing humidity levels, which is essential in environments where moisture control is necessary, such as food processing plants and greenhouses.5.Air Destratification: In tall buildings, HVLS fans can help destratify air, breaking up layers of hot air near the ceiling and mixing it with cooler air at ground level, thus maintaining a more consistent temperature throughout the space.Conclusion:For mechanical engineers and mechanical contractors, incorporating HVLS fans into your designs and installations can provide significant benefits in terms of energy efficiency, air quality, and occupant comfort. Whether you’re working on a new build or retrofitting an existing facility, HVLS fans offer a practical solution for improving air circulation in large spaces.Matthew Spink, P.E.

CounterFlow vs CrossFlow Cooling TowersWhen selecting cooling towers, it's essential to consider the specifics of the job requirements. Smaller tonnages below 750 tons may benefit from counter flow designs, though for capacities above 750 tons, cross flow towers typically require an additional module, forming a double-decker setup.Evaluating each project’s unique needs rather than relying on a one-size-fits-all answer is crucial. While it’s tempting to seek straightforward answers, the correct solution often depends on various parameters, a nuance learned early in the industry.In addressing system optimization, particularly from an energy and water efficiency standpoint, one common question is why choose evaporative cooling over dry cooling. Dry cooling can simplify operations by eliminating the need for water management and the risk of freezing, but it sacrifices energy efficiency due to its reliance on sensible cooling alone.For instance, cooling one pound of water by one degree Fahrenheit removes only one BTU, whereas evaporating the same amount of water removes nearly 1,000 BTUs. This significant difference underscores why, despite the complexities, evaporative cooling often remains the preferred choice in terms of energy efficiency.SPX Cooling Tech, LLC
