Refrigerants

[AKHou]

We are retrofitting our Central Plant.
Two original chillers with R-11 will be accompanied by two new R-134a refrigerant chillers. Should we be concerned with housing these two different refrigerants in a small central plant?

I dont see why. I just know down south here they have code for ventilation of mechanical rooms. The 2 refrigerants shouldnt be a problem as long as the room ventilation is ok.
(you know flammability stuff and ability to support life stuff)
HHmmmm make that commercial mechanical rooms. I dont think residential mech rooms have a spec on that.
