⚠️ ASHRAE 15 / 34 RCL Safety (26 Lbs / 1,000 Cu Ft for R-410A), Leak Safety Shutoff

ASHRAE 15 VRF Refrigerant Concentration Calculator

Model life safety compliance for commercial VRF systems under ASHRAE Standard 15 & 34: calculate smallest occupied room volume (Cubic Feet), verify maximum allowable total system refrigerant charge (RCL limit = 26 lbs / 1,000 cu ft for R-410A or 13 lbs / 1,000 cu ft for R-32), integrate automated refrigerant leak detection sensors, and safety margins.
