Why did you "figure" that? Black paint doesn't make things "dissipate heat".
As noted all hermetic compressors are cooled by the refrigerant. Any cooling of the small steel case of the compressor...

I'm not sure why you are arguing. What you are talking about is in no way helpful or relevant to air conditioning a "van" or a Jeep. There is nowhere to store ice, and even if there was you would...

There are some newly available small DC compressors mostly from chinese sources for things like this. Much of it is 24v but I'm pretty sure they make 48v compressors too. From there I would rather...

That's a problem I wrestle with a lot. I don't plan on living in this house the rest of my life, so I have to think hard about how much these upgrades are worth. I'm glad the previous owner put in...

I'm not talking about what the window unit is actually "rated", but rather measurements I have taken myself. I've never seen it go over something like 412w on a hot day, though I have not done...

I disagree.
First, the particular unit I have makes 5,000BTU at about 350-400 watts depending on temperatures. This gives a COP of roughly 3.75. No, not as good as a mini split, but not...

I think it might be better (cheaper/easier) to use a non pressurized tank with a pressurized copper coil heat exchanger inside. You could use a stainless steel 55 gallon drum for this, or probably...

Converting vehicle A/C from R134A to propane?
I have a 1998 Jeep and the air conditioning has a very slow leak. It's not a big deal, I only have to top it off about every 6 months. With that said, I'm interested in converting it to use propane...
