We live in a fairly humid coastal area.
I bought a dehumidifier for my 10x8 outdoor grow shed but am finding that when it’s warm outside the dehumidifier plus 900 actual Watts of LEDs heats things up a bit too much during the day but it’s perfect at night with just the dehumidifier running. I run a 90CFM exhaust fan only when the lights are on.
Im thinking of switching it for a portable air conditioner so that I can redirect a percentage of the heat from the units warm air discharge duct back inside.
I could use some kind of temperature controlled diverter vane to regulate the warm return air.
I think this could work unless these portable units try to reject humidity through the discharge so there is less condensate water to get rid of. This would completely defeat my plan.
I’m wondering if this would use more power than a regular dehumidifier also as this is not the intended use for an A/C unit.
Has anyone experimented with using A/C for dehumidification? I would be interested in hearing what works.
