#hvac #course by authorScriptHvac is the second most energy consumption on ships, special care with sophisticated control systems are to be used to save energy.Fire, smoke and corrosion control are of highest importanceHeat loads: solar , sensible, latent, occupants, lighting, wall/roof gains, electrical equipment, hot piping, Fresh air, infiltration, motors. (ventilation, solar and skins conduction varies to the area of ship operation) Maximum to be allowed.HVAC can be DX, usually for smaller areas and chilled water for large halls but not the rule.Condenser units use sea water with heat exchangers and sometimes air where permissible.Cabins HVAC, FCU units are also used for independent control, some cabins are pre manufactured and then slide in one by one during construction.Diffusers: special attention to diffusers due to low ceilings, not to cause drafts.VAV systems are used for energy control and sometimes dual duct systems are used.AHU sections: Filters, HEPA for crowded spaces (atrium, cinema, dining areas etc...) heat recovery wheels, coils, (heating , cooling) humidifier, sound attenuation. Plus two condensate drains due to ship movement.Ductwork: preferably round due to tight spaces as well protected against fire, attenuation lining.BMS: of highest quality and most advanced systems to save energy and control well the humidity level.Fresh air: to be adjusted with amount of CO2 detection in large areas, atrium, dining, cinema etc...Spares parts: always to be ready on board as the ship is far from land. ex: oil, refrigerant, filters.Coils: copper tubes, fins also exposy coated.Chilled beams are also used to save on energy and space.For more details or consultation please contact www.cfn-hvac.com
