My wine store needs cooling. It's smoothing out temperature fluctuations, but it's getting to hot during heat waves.
Id like something based around 12v DC so that I can use solar/SLA battery, although 240v is possible.
What approach would you take?
The store is an insulated "box" of about 2m3. The walls are foil backed 40mm polyurethane foam panels (like Celotex/kingspan) so really easy to cut/drill for ducting or pipework.
Im not sure a Peltier device approach is going to be sufficient, so am looking at compressor/condenser approach.
Would an old fridge be usable for parts? or car air conditioning unit? or perhaps a dehumidifier (I have one sitting idle)
bodgers, I need you.
Here's the problem:
