Location: Hotel – Fort Lauderdale, Florida  Overview: A 6-year-old York YCAV air-cooled chiller serving a hotel experienced premature condenser coil failure. Out of 10 total coils, 4 had already failed (40%), with the remaining coils showing active corrosion. The unit operates continuously, making reliability critical for guest comfort

New refrigerant requirements from EPA mandates aimed at reducing greenhouse gas emissions are shaking up the HVAC industry. These requirements are causing a shift from R-410A refrigerant to A2L refrigerants R-454B and R-32. A2L refrigerants are low in toxicity and flammability. The shift is based around a metric called GWP, standing for Global Warming Potential, which measures how much heat a gas traps in the atmosphere compared to carbon dioxide. R-410A has a GWP of around 2,088, which means that 1 pound of R-410A released into the atmosphere has the same warming effect of 2,088 pounds of CO2.

Increasing demand for AI, high performance computing, along with hyperscale data center expansion are creating a massive new market for HVAC. The shift is in cooling, as data center cooling is moving beyond incremental airflow optimization, and towards liquid cooling in order to support AI and its specific cooling needs. Because of this, the data center liquid cooling market is projected to expand from 6.6 billion dollars to 38.4 billion dollars by 2033. North America is the current hotspot for this investment as it hosts the largest concentration of AI training clusters globally. Historically, data centers have relied on air-based systems for their cooling, which includes CRAHs, chilled water systems, and precision cooling equipment. Because AI servers are now generating higher heat loads than previously (Modern AI racks can exceed 100 kW per rack compared to the traditional 5-15 kW loads of the past), facilities need heavier duty cooling, sparking the transition to liquid cooling solutions. This transition to liquid cooling is not removing HVAC systems and instead restructures their role within AI facilities. Removing building heat, maintaining environmental conditions, and supporting chilled water distribution systems are all issues that HVAC remains a critical solution to. As a result of this, specialized coils, such as the ones HeatEX produces are growing in demand along with cooling towers, heat exchangers, and other thermal regulation components necessary for dealing with high heat rejection requirements. This trend to support AI with Liquid cooling brings new challenges with infrastructure and compatibility for projects, as operators prioritize power usage effectiveness reduction and carbon footprint optimization. Ensuring coolant compatibility with diverse server architectures, leak prevention, and aligning cooling with rapidly advancing cycles are a few of these challenges. Operators are looking for companies that can specialize towards their plants and customize them to their need.
