Ventilation systems on casino boats, cruise ships, yachts and other large vessels have different ventilation requirements depending on the size and amount of people onboard. Casino boats and cruise ships previously relied on filtration systems, but have since switched to “fresh air mix” ventilation, especially in public spaces and staterooms. Mixing fresh air with circulated air reduces costs, but more importantly keeps pathogens from spreading. HVAC systems continuously supply 100% fresh, filtered air from outdoors to all indoor spaces.
In addition to fresh air mix, HEPA filters are applied. The air is also treated with UV-C light to eradicate viruses not caught in the HEPA filter. UV-C light has been proven to kill coronaviruses like COVID-19 (FDA Source).
Most yachts are gasoline powered and are regulated by law to meet ventilation requirements. Fumes from the yacht’s engine can accumulate in the bilge, which increases the chances of explosion if not ventilated properly using heavy-duty marine fans. Then there is the excess heat that is generated by the yacht. The heat not only diminishes the boat’s engine, but reduces alternator output and battery power. Other issues of a poor ventilation system on yachts are damage to belts, hoses and engine components.
Excess heat not only impairs engine performance, but reduces alternator output and battery power, and can damage hoses, belts and other components.
