I need help with selecting air cooling-heating equipment for a high humidity environment within a new insulated outdoor chamber for a test laboratory in Florida.
A new 20' L x 10' W x 10' H chamber with 4" styrene insulation in aluminum panels forming walls and ceiling will contain those samples and a nozzle-free axial fan that can atomize ordinary water and propel a misty-fog stream up to 20 feet away.
The chamber has been installed on a concrete slab on grade with two floor drains.
Many material samples (5" diameter x 12" length) should be kept very wet and within a temperature range of 70 to 77 F degrees.
Those will be located in floor-to-ceiling racks that allow free circulation of humid air all around them.
My rough first idea has been to install an outdoor air-cooled heat pump for cooling-heating of very humid air, combined with an indoor air handler unit able to operate within that humid environment without inducing too much condensation (walking cooler type).
The internal insulation, blower motor and electrical heater elements of a regular AC air handler unit seem not to be suitable for managing saturated humid air.
Walking cooler condenser units seem unable to keep only the required temperature range of 70 to 77 F degrees.
Do you have experience with those, or simply a better idea or approach?
Thank you.
