Free cooling within air-conditioning systems is a proven method for improving energy efficiency. It makes sense to tap free colder outdoor air to cool the environment inside your building. Free cooling avoids running the compressor while keeping buildings at the right indoor conditions. Whether it’s for a process or comfort, free cooling is more sustainable with lower energy and operating costs.
This session takes a deep dive into different types of free cooling solutions for chilled-water systems including air-side vs water-side economizing and integrated vs standalone options, identifies key strategies for optimizing free cooling in system design including data centers, and explains new developments in free cooling controls that deliver enhanced efficiency to customers today.

Preparing for A2L Refrigerants
Familiar refrigerants, including R-410A, are being phased out in newly manufactured equipment, with next-generation, low global warming (GWP) refrigerants becoming the new reality. These new refrigerants, classified as A2L, have been described as having "lower flammability" characteristics which will impact how systems are designed, installed, and maintained.
