May 2025 Chapter Meeting

Hydronics as a solution to achieve Electrification and Decarbonization

Presentation Abstract:  Refrigerant transition towards low GWP and A2L class refrigerants is a key topic in HVAC market today. This presentation will explore a system-wide approach for application of centralized heating/cooling plants, centralized ventilation and terminal units leveraging low-temperature heating and high-temperature cooling to achieve a comfortable low-carbon HVAC system.  An overview on chilled beams will be provided, highlighting how they can be leveraged to optimize efficiency of overall hydronic system and improving thermal comfort and IAQ, and how integrated design with respect to the ventilation system and central heating/cooling plant must be considered.  The presentation will conclude with a case study project where low-temperature heating and high-temperature cooling was leveraged to provide a low-carbon design without sacrificing indoor air quality, thermal comfort or energy efficiency.
