One of interesting-if-too-expensive methods I've seen was basically having gas powered heat pumps.
IIRC It was basically using normal gas engine to move the coolant around but it also used heat produced by engine to heat the coils on the cold side so it was getting essentially more than 100% efficiency out of gas.
But it was even more expensive than traditional heat pump.
- seiferteric 3y agoAh sort of co-generation, sounds interesting.
- tomatocracy 3y agoSounds a lot like the idea behind combined cycle gas turbines.
- undersuit 3y agoYou can get refrigerators that will run off of compressed propane. Popular in RVs when you don't have electricity.
- ilyt 3y agoPropane is also used in some new fridges and in heat pumps. I remember some fridge manual where it said minimum room size because they basically did the calculation "if it escapes and room is at least that big, it won't be stoichometric mixture and cause masssive explosion. I also heard rumours people with old cars that had AC running on freon use it as replacement...
- beerandt 3y agoOne of the reasons for natural gas prices increasing is that the compressors that power the system have historically been gas powered, but all federal permits in the last decade or so have required electric compressors, even in remote locations. And not just new installs, but for existing work/ upgrades. It's a 2-for, in that price increases and reliability decreases, since the gas grid now requires the (remote) electric grid to work.
