When a boat owner moves from a traditional HVAC system to one of the TMD Marine HVAC units, the difference is noticeable. Not just because our units work so well, but because the old issues that boat owners inevitably have to tolerate with other marine AC units; are suddenly gone. Sounds too good to be true? In this article, TMD Marine will explain how traditional units work, and then how TMD Marine AC units work.
Traditional Marine Air Conditioning
Marine AC differs from land-based AC because it tends to use “water cooling” versus “air cooling” technology. This has likely been due to a lack of space (which is usually needed for air-based systems and well, how much water is available. There are typically two types of these “water-based” systems.
- Refrigeration Types; Such as a 110V or 12V system that produces dry, cool air
- Evaporation Style; Usually 12V and delivers cool (damp) air like what one gets on the water.
With a closed loop, the refrigerant system uses the premise of condensing and evaporating “refrigerant” chemical to produce the cool air. This is done with high and low pressure using a compressor to do the work to control the temperature. It is more complicated than that, but that’s a general idea.
With an Evaporation style system, cooling takes place with water or ice. A fan is applied to one of these elements which is then used to cool down a small space.
Some of the most common problems with standard AC units are:
- AC won’t cool
- Produces loud noises
- The fan malfunctions
- Creates repugnant odors
- Can create mold and bacteria
Almost all of these problems are based on “moisture” which is what TMD Marine took head on in creating their product line. Not only are our products designed to tackle the problems listed above, but they also give vessel owners new control over the climate of their cabins, that they haven’t ever had. Here is a look at how one of our HVAC units works.
This is a self-contained system that is built with a titanium condenser and a variable speed compressor. It’s powered by 24 Volt DC energy and produces 16.000 BTUs in cooling status. The unit maximized pressure (145-PSI) which is both safe and eco-friendly. The system is “on demand” meaning the compressor is designed to detect and react to satisfy heat and cooling preferences. It does this through the variable speed compressor.
One of the most unique things about this water cooled unit is that it uses a titanium heat exchanger, which won’t be found in any other HVAC system in the world. This tackles the issue of corrosion that leads to traditional unit’s failing, as titanium is incredibly saltwater resistant.
The system is guided by a microprocessor system that uses advanced controls to monitor and prevent damage due to things like pressure and temperature. This can be all done from a touch-screen device giving the captain full control over troubleshooting and advanced climate control options.
