Walter Stark has spent his professional career serving the HVAC industry, and the past thirty years specializing in dehumidification, making him one of the leading experts in the field. He is best known as the inventor of the MSP Dehumidifying Coil, which saves up to 70% energy. He also holds a number of other HVAC-related patents. An award-winning visionary and entrepreneur, Mr. Stark has been the recipient of the Governor’s Award for Energy Excellence in New York, and a grant from the New York State Energy Research and Development Authority. Popular Science magazine has honored his invention among their Best of What’s New. Mr. Stark has served as President of his local chapter of the American Society of Refrigeration Air Conditioning Engineers. His clients include such large firms as Walmart and Hasbro. Mr. Stark’s company, MSP Technology, is active in the field of dehumidification and the emerging field of indoor plant-growing, providing HVAC and dehumidification equipment, design, and project management services.
Hello, This is Walter Stark, ready to take your questions. I’ve attached documents on a case study on Humidity Control in Indoor Agriculture and a Vapor Pressure Deficit Chart with explanation.
Please keep in mind that we are engineers, not horticulturists. Our job is to provide you with the environment you specify to help your plants thrive. That said, when issues fall close to the line between engineering and horticulture, we share our opinion.
In the case of indoor grows, the air is recirculated with introduction of little or no outdoor air. The only load is the envelope which is usually low compared with internal load such as lighting.
What software do you like to use for monitoring and recording climate control data? Do you have your own software platform or do you partner with someone for that?
MSP equipment has only one moving part–a highly reliable beltless fan with EC motor. So, a spare fan or two would be advised. The chiller or refrigeration system should have redundancy. Multiple compressors with multiple circuits can ensure continuous operation during failure,
We have been removing moisture from air for more than 20 years. About 3 years ago we saw the indoor growing opportunity and, after close investigation, discovered a market superior for MSP Technology.
Hi I am Yonatan from DryGair, Thank you Doctor. Great to be part of this discussion.
During the day when lights are on, the plants evaporate 10 times more than during the night.
How do you deal with this high evaporation rate?
