What size aircon do I need for 60m2?

Generally speaking, you’ll need roughly about 0.15 kilowatts per square metre. For example, a smaller room that measures 20 square metres would need an air con around 3kW, while a 60 square metre room would need a device capable of delivering around 9kW.

Can I use a portable air conditioner on a boat?

Unlike a window unit, the entire AC is inside, and the duct allows the hot air to vent outside. NOTE: A portable air conditioner is NOT the same thing as an “evaporative cooler” (also known as a swamp cooler). Evaporative coolers just don’t do much in places with high humidity and thus are unsuitable for most boats.

Do boats have AC?

What is reverse cycle air conditioning on a boat?

Most Cruisair, Marine Air and Dometic AC Systems have a reverse-cycle mode, which changes the flow of refrigerant and turns your AC system into a heat pump. The compressor pumps hot, pressurized refrigerant into the air handler where it transfers its heat to the cabin via the flow of cool cabin air over the coils.

How bad are portable air conditioners?
