HVAC Cooling Load (Sum of Components)
Total sensible + latent cooling load - sum of solar gain, transmission, infiltration, occupants, lighting, equipment, fresh-air make-up.
Raw load
30.50kW
Sized load (with margin)
33.55kW
Formula, assumptions, and limits
Sensible + latent combined. For proper HVAC sizing split sensible and latent and run a coil-selection program (sensible heat ratio matters for dehumidification). Shipboard AC typically sized at 10–15 % margin.
