Main Presentation - 6:45 pm - Selection of HVAC Equipment for Controlled Environment Agriculture

Main Presentation Highlights: Dan Dettmers

Controlled Environment Agriculture (CEA) is a term used to describe the production of plants in a facility that is partially or fully enclosed from the elements.  This allows fruits, vegetables and other food to be grown out of season or in locations where they would never grow in the first place.  Originally, CEA primarily meant growing in a greenhouse.  As the industry progressed, it evolved into hybrid greenhouses and into completely enclosed indoor horticulture with artificial light and a full HVAC system.  The fully enclosed system has been dramatically pushed along by recent legalization of the cannabis industry.

In this presentation, Dan will present some of the challenges of conditioning an indoor grow facility, including cooling loads as high as 25 ft2/ton, latent cooling load that rival the sensible loads and amazing filtration requirements for both supply air and exhaust air.   He will touch on the space requirements, cooling loads, latent loads and “watch-outs” for greenhouse tomatoes, vertical farm lettuce and…yes…cannabis.  Likewise he will provide details on many of the prevalent myths in selecting HVAC equipment for CEA and the reality of how the equipment performs in the field…or the indoor field, such as it is.
