Thermal image of a road that was just repaved
(thelemmy.club)
I could feel the heat coming off it when I stood next to the repaved section. They didn't repave the parking area at the edge. Opened to traffic again, seems firm enough to drive on at 160⁰F.
So, where does that heat go?
Last I checked, a fridge uses the outside air to cool the heat exchanger
Yes, and it cools stuff to cooler than the outside air, right?
Last I checked, my fridge works even when the room is warmer than the fridge.
Compressor heats up coolant, coolant exchanges heat with outside, cools down then evaporator cools it further, heat exchanges with cold loop then goes to be compressed again. It's the same principle that freezers and ac use, with the phase changes of the coolant you force them to move thermal energy in the desired direction.
