I've a small Peltier cooler which I used to store some chemical stuffs. So, I recently modded the design to make it more bigger and improve its cooling + insulation.
I've added an aluminium piece plate as the base which is in contact with the cold part of the Peltier, the other four sides are covered with thermocole. I keep it running 24x7 on my atx power supply. I have installed a refrigerator gas expansion thermostat in it to turn-off once it is sufficiently cool inside(-1C to 0C).
My question is how does the cooling change if I stick aluminum tape on the inside of the thermocole insulation (interior of the cooling cabin) and make it reflective? Will it increase the cooling capacity and reduce the power-on time?
Note: I've posted it here since most of the Peltier questions are here. If this is the wrong forum please guide me move it to the appropriate forum.Thanks.
