It's called R-290 [0], but yes this is the same as in "propane grill."
I'm a "consumer," but the technicians I talk to about replacing a residential HVAC have mentioned that consumer HVAC systems need new fire detection (maybe also suppresion?) systems on the A/C side just because of the new ingredient.
Again, not propane for the heating side, but for cooling. Crazy.

- SoftTalker 2y agoI wonder why they don't just put the whole chilling unit outside and use a chilled water loop into the interior air handler.
- tristor 2y agoYou could do that, but you'd need to build a heavily insulated place to have the A-coil/evap head, as it stands right now the efficiency loss would be too much. Additionally, the current HVAC model also acts as a rudimentary de-humidification system for buildings which helps reduce the "felt" temperature and maintain humidity levels beyond just cooling.
