Temp and Rh control year round in northeast
Temp and Rh control year round in northeast
(OP)
I have a 12 X 15 X 12 room that i am trying to control temp to +,- .05°c and +,-5% rh. I have the temp problem undercontrol but the problem i have is reducing the rh in the room and i feel the problem is i cannot get the chilling cold enought to remove enough of the water i am thinking of going with a split system instead of the chilled water system.The problem i have is when winter comes around the head pressure is going to be to high. Is there a system i could chill the compressor coil with water to remove the problem of trying to run in below 20°f.I now use electric heat with constant cooling and the temp controls well. I figure if i could get the coils to remove more of the Rh I could actually get control of the Rh. This is needed to contol the temp and Rh in a dimensional lab. Any suggestions or help would be greatly appericated,Joe

This is not reasonably achievable with conventional chilled water or DX systems. You would need to seek out alternative dehumdification systems - e.g., desiccant dehumidifiers. I don't think Grainger would stock anything for your application because a normal dehumidifier uses a typical refrigeration circuit, which might get a room dewpoint as low as maybe 45°F, not 31-35°F to suit your need.
Search for desiccant (one S, two C's - if the seller can't spell it, it's probably not worth buying from them) and see what you turn up. Regards, -CB
