VRF Rejected by the US Military? DoD has placed special requirements on these systems due to their inherent risks.

Three primary risk areas have been identified:

1) VRF systems currently contain proprietary hardware and software in conflict with 10 USC 2867,

2) VRF systems increase the risk of adverse mission impacts due to new EPA leak-rate rules on HFC refrigerant systems (if 50 lbs or greater of refrigerant) and the challenge of locating and repairing a leak in often hard to access areas 

3) VRF systems have uncertain lifecycle costs (LCC) making comparisons with traditional HVAC systems difficult.
