Milwaukee, WI – Grow room operators trying to get tight control of relative humidity and temperature to increase crop yields have a new friend in Desert Aire’s GrowAire™ Systems, on display at AHR Expo 2017, Booth #C1920.
GrowAire™ Systems combine the control of space conditions into one platform. This overcomes the weaknesses of the typical grow room approach. These include conventional air conditioning units and supplemental dehumidifiers fighting each other with limited effectiveness, as air conditioning units cool the space and dehumidifiers add waste heat.
Desert Aire provides engineered solutions to climate control challenges as well as evapotranspiration issues. These solutions help growers prevent the formation of biological contaminants as well as save energy and resources.
Desert Aire configures GrowAire™ Systems to meet specific grow room needs. The systems feature an advanced refrigeration design that can vary sensible heat ratios and adjust room temperatures independently of space dehumidification needs, responding to the significant differences between lights-on versus lights-off modes.
Integral to this design is a modulating hot gas reheat system. The system employs several custom proportional, integral and derivative (PID) control algorithms to adjust actual leaving air temperature, teamed with a zone temperature sensor to create a feedback loop. The system also uses dewpoint sensing to ensure it engages the correct number of stages for dehumidification control. This allows the system to efficiently achieve the exact amount of zone cooling or heating required independently of the demand for dehumidification.
GrowAire™ systems range in size from 1 to 60 nominal tons of refrigeration capacity to serve a wide variety of indoor growing spaces, drying rooms, curing rooms and packaging areas. The systems meet conditions from 65°F to 85°F at 45% to 75% RH.
Desert Aire offers several control choices to integrate GrowAire™ systems with building management networks. More information is available at Desert-Aire.com.
