Let’s Worry More About Refrigerant Leaks, Less About Metrics

When I first started writing about the HVACR industry more than 25 years ago, the term used to describe the harmful effects of refrigerant emissions in the atmosphere was ODP. After scientists discovered the hole in the ozone layer, they determined that it was caused by the chlorine in chemical compounds like CFCs, which were widely used in aerosols and refrigerants. They needed a measurement to describe the amount of ozone depletion caused by various substances, thus the term ODP was born.

On Demand As AI workloads and high-density computing push traditional cooling methods to their limits, the data center industry is accelerating the adoption of next-generation HVAC technologies.

In this session, we will cover how to design VRF systems for the U.S. market using new A2L refrigerants. These systems provide an advanced zoning solution by using inverter technology to deliver precise heating and cooling control across multiple zones and spaces.
