HVAC - Accommodation Cooling Load
Accommodation cooling-load estimate from transmission, solar, internal + ventilation gains - the chiller-sizing baseline.
Total cooling load
225kW
Formula, assumptions, and limits
$$\dot Q = Q_{trans} + Q_{solar} + Q_{int} + Q_{vent}$$
Rule-of-thumb 0.35 kW/m² for cruise / passenger, 0.25 kW/m² for cargo. Large cruise ship HVAC 5-8 MW cooling. Chiller + AHU + reheat coils.
