After reading another thread here I became intrigued with the idea of cooling a terrarium to give a more natural drop in night time temperatures. I thought I'd start with items I had and experiment with them. I have a complete peltier unit with cold and hot side heat sinks and fans. I also have an unused terrarium I bought on Kijiji some time ago. I'm aware that cooling the air will not bring down the temperature an acceptable amount. So while I wait the 6-8 weeks for a water block and other parts to come from China I thought I'd play around.
Here's my terrarium with some weatherstripping added.
I had some extra 6mm baltic birch plywood so that will become my top for now. A Google search tells me the R value is about 0.3.
I had an extra 10A power supply in my parts bin so that was wired up.
Hi Dave - Sorry to hear of your results. Don't worry though, that sounds about right from my experience as well. I always want thermometric cooling to work better than it does. I love the precision of your data collection though. That's really awesome!!!
