How Are Marine Air Conditioners Different from Traditional Air Conditioners?

Most people prefer to use a traditional air conditioner system, similar to what we use in our homes, offices, etc., in their boat as well. However, there are specific air conditioning units designed for marine use which are much better.

Unlike ordinary air conditioners, the marine-specific AC units also dehumidify the surrounding apart from heating/cooling the area, thus reducing the temperature and keeping the boat dry. A dry cabin will help in avoiding any foul smell and protects the onboard systems and electronics from being damaged or corroded.

There are several other differences that make marine air conditioning systems more efficient. In this article, we will be taking a look at how marine air conditioners are different from traditional air conditioners.

How Marine Air Conditioners Differ from Traditional Air Conditioners?

Better Power Efficiency

Traditional air conditioners are power-hungry. Drawing such amount of energy from the boat’s power supply can affect the electric supply to other vital equipment and systems within the boat.

TMD modern marine HVAC units come with features and technologies that reduce power consumption.

Variable frequency drive (VFD) technology used in modern marine HVAC systems starts the compressor smoothly without drawing all the necessary power at once, thus avoiding any power surge issues when the air conditioner is switched ON.

Similarly, when the marine HVAC system is switched OFF, instead of abruptly terminating the power supply, it is gradually reduced and then cut off.

Apart from that, the advancements in technology and electric circuitry ensures that a minimal amount of power consumption occurs when the air conditioner is functioning.

Models Suitable for Every Boat Type

Companies offering marine air conditioning systems have different types of units available suitable for different kinds of boats.

There are different types of marine air conditioning systems, such as air-cooled or water-cooled systems that customers can choose depending on the size and capacity of their boat.

Choosing the correct type and size of the marine air conditioning unit ensures that it takes up less space and is power efficient. Moreover, such a unit will provide efficient heating/cooling in the cabin at all times.

Evaporative Air Conditioners for Smaller Boats

There are two main types of marine air conditioners: refrigerant marine HVAC and evaporative marine HVAC.

The refrigerant type air conditioners work similarly to the AC or refrigerator that we use in our homes. There will be a refrigerant gas that runs through the AC unit in a closed loop. Within the loop, there will be high-pressure and low-pressure sides.

When the fluid reaches the high-pressure side, its temperature rises due to compression of the loop. The hot refrigerant gas is then cooled and turned to liquid form with the help of the condenser. Now, the hot refrigerant in its liquid form is passed back to the low-pressure side where it is heated and evaporated back to the gaseous form. The heat to evaporate the refrigerant is taken from the temperature in the surrounding. Thus the room becomes cooler.

Evaporative air conditioners, on the other hand, use water or ice for the cooling process. Water passes through a system containing a high-speed fan that blows out cold air into the surrounding, thus reducing the temperature.

Evaporative marine air conditioners are best for boats having a smaller area. Moreover, they also consume way less power than refrigerative air conditioners.

Final Words

It is very evident from this article that marine air conditioners are a better choice for boats and ships that traditional air conditioners. While choosing an air conditioner for your vessel, make sure to pick a marine HVAC unit that works best with its size and capacity for better results.
