"temperature control" is a general tool required for lived spaces. Heat and cool the house. Heat water. Cool the fridge and freezer. I suspect that there's a lot of wasted energy pumping heat from your groceries twice. It seems dumb to pump heat to the outside then turning around and running your water heater. What if there were a centralized temperature control distribution hub and pump, so you only needed one for the house that would serve all of these applications?
