It sounds like you're planning to seal your room at some point. I'm the Farm's resident water chilling evangelist- meaning that I tell people to skip the usual rat race of buying a tiny chiller for your RDWC, then an AC for the room- and then a dehuey because the AC unit doesn't manage humidity very well. All that stuff might be relatively affordable to buy piecemeal, but it adds up to a big number- and worse, that gear all tends to work against one another, making a real mess of your power bill in the process.

The solution, provided you can swallow hard for the initial expense, is to upsize your water chiller purchase to one full Ton (not one 'horsepower', which is a smaller unit of measure) per 4kW of sealed and vented lights, or 3 open or bare thouies. It will then be able to effectively chill your RDWC, cool your room and manage your humidity efficiently because each cooling function happens in symbiosis with the others- allowing you to save up to 75% on your total cooling costs over AC, and regularly 30% or better even over modern minisplit units. The difference is the chiller is an integrated solution. What's more, you could add a second room of the same size on the flip and your chiller would handle it without a hitch- the ability to send water where you want it via hose makes adding another space simple.
