I wanted to make a fridge, but there are no elements that make an endothermic reaction. How would you approach this problem, is it even possible?

If not, this is the proposition of the new element "ammonia" (AMMN). We lerned in chemistry that it can be synthesized using two chemicals, with a literally cool side effect. When my teacher gave the bottle to a classmate, he said it's "unreasonably cold".

I'm not sure which chemicals it was, but the formula of ammonia is NH³. Therefore, in PT, the required elements could be HYGN and SMKE. Why SMKE? Because adding a gas form of NICE or LN² would break so many old saves, and you need a hot environment and a spark to trigger the reaction.

Then, to release the stored heat, AMMN needs to be depressurized, making it split up into HYGN and SMKE again. This can be used to create an endless cycle, making coolant systems more realistic and adding more uses to them.

That's exactly what I don't want to do. I want to create a heat pump, which transfers heat from one area to another, especially from a cold area to a hot one. This could finally make that life workaround obsolete. Also it can transfer heat much faster and more efficient than any other option I've seen so far.

 Ambient heat creates more problem than it solves. You can't control it in any way.
