Understanding the Advantages of DC Aircon


The success of lithium battery setups with solar power and high capacity battery chargers reduces the reliance on traditional marine generators.  Many boats with no longer need a generator or have substantially reduced the number of hours they run.  Advantages of lithium batteries include less noise (the silent ship), reduced fuel bills and lower maintenance,  Portable Honda type generators can adequately charge batteries and run appliances.

The advent of variable speed DC compressor motors adds a new dimension for air conditioning in boats.  A DC aircon will connect directly to lithium batteries and there is no need for an inverter or generator.     A 10 KWH lithium battery can power a ROTO 12,000 BTU  DC aircon for about 12 hours or more without any charging.  

A traditional AC aircon compressor turns on and off depending on the thermostat setting.     A ROTO DC variable speed aircon continually adjusts its compressor speed based on the temperature setting.  It is a more efficient air conditioning system.

Other advantages of a DC aircon include no overloading of smaller generators and no tripping shore power circuit breakers on marina power posts.  DC aircons provide an off grid solution for marine aircon.

If you are making the change to lithium and need aircon, the ROTO range of DC air conditioners is worth a look.  12, 24 and 48v systems are available.


Case Study:  Replacement of 25 Year Old Cruisair 7BTU Split System

Customer's 7K split systems compressor had seized.  Spare parts and gas for this old R22 compressor are no longer available.  The decision was made to replace the unit with similar new reverse cycle  split aircon.  Steps included were to discharge old R22 gas for storage/disposal, remove old condensor and evaporator, modify copper piping to suit evaporator and condensor hosetails.  Made use of existing AC wiring and installed new wall control.  Total time taken to remove and replace old condensor and evaporator with new and gas system..... 3.5 hours to testing stage.  Of course wiring runs and installation of wall control into woodwork took longer and can were completed by the boat's owner. New simple to read control allows automatic fan speed and temperature setting.
