This live podcast focuses squarely on the ASHRAE 34 A2L classification and its implications across HVAC equipment, mechanical spaces, transportation, storage, and building codes. But what exactly are A2L refrigerants?
Named after their ASHRAE safety classification, A2L refrigerants exhibit mild flammability, low toxicity, and a low global warming potential (GWP). This category encompasses hydrofluoroolefins (HFOs) and HFO blends. A2L refrigerants mirror the operational characteristics of legacy refrigerants while presenting a safer profile compared to ammonia and hydrocarbon-based refrigerants.
As the world grapples with climate change, A2L refrigerants have emerged as a substitution for older, high-impact refrigerants such as HFCs and HCFCs in air conditioning and commercial refrigeration setups. A2Ls are pivotal in aiding businesses to meet global objectives outlined in agreements like the Montreal Protocol and the Kigali Amendment, as well as regional regulations such as the U.S. AIM Act, Canada’s ODSHAR, and the targets of the EU Green Deal.

Unlocking Cleanroom HVAC Design: Insights from Bo Coffman of Nortek CleanSpace

In this LIVE episode of The Engineers HVAC Podcast, Grow Room experts Kirk Patton and Chris Adams, PE, share their experience successfully selecting, controlling, and supporting HVAC systems and controls in Grow Room applications.
Indoor grow rooms have revolutionized the cultivation of plants, particularly cannabis, allowing for year-round growth under optimized conditions.
However, creating and maintaining these ideal environments involves navigating a complex interplay of factors, from temperature and humidity to light and air quality. Unlike typical office or commercial spaces, grow rooms require highly specialized HVAC design approaches to meet their unique needs.
The Unique Challenges of Grow Room Climate Control.
The primary challenge in grow room design lies in the precise control required over the environment. Plants are much more sensitive to climate conditions than humans, with specific temperature and humidity ranges needed to maximize growth and yield.
Additionally, transitioning from traditional lighting to energy-efficient LED options has altered the thermal dynamics within grow rooms, affecting heat loads and enabling multi-tier cultivation. This lighting evolution necessitates advanced cooling and dehumidification strategies to handle the reduced heat output and increased plant density.
High humidity presents another significant challenge: plants transpire water into the air, dramatically increasing moisture levels.
Grow rooms require robust dehumidification capabilities to manage this moisture without overcooling the space, especially during light-off periods when plants continue to transpire.
Air quality and circulation also play a critical role in plant health, necessitating the integration of air filtration and purification technologies.
Contaminants, VOCs, and pathogens can adversely affect plant development, making specialized filtration systems, including HEPA filters and UV light sterilization, essential for grow room HVAC systems.
