The system pumps cold water around the building for airconditioning.
Inside the compressor looks like a jet engine. Large turbine blades etc..
The total pressure of the system is - 10 psi. Yes, negative pressure. If the evaporator or compressor were to rupture, it would actually suck air in for awhile, then start leaking refrigerant.
R-123 is still a liquid around room temperature, so it must be heated before it can be used in the phase change process.. Weird.
If there ever was a situation were a leak occured and someone was present in the room, the refrigerant would displace all the oxygen and the only way to save th person would be to turn them upside down the let the refrigerant fall from their lungs..
Interesting.
