Hi Ali

the cooling plate connected to the compressor (the heart of the system)
the compressor compares gas through the pips and the cold plate and by that freeze them. the result is refrigerator.
the system works great for me , a week ago the temps where above 30 c, reaching probably 40 c. and the temps in the terrarium where 17 day 11 night.

I will try to make it more clear tomorrow
