I just got one of those last week. I have it cooling a room with a FrankenJup and an S1. The room now stays at a chilly 85f, lol. But at least the home A/C can now switch off once in awhile. It was running 24/7 otherwise.
I am not sure about the thermodynamics of it. Where does the heat exhaust go? In other words, does it have windows exhaust? Heat has to be transferred somewhere.
