DC Refrigeration
Off-Grid Direct Current (DC)
refrigeration does not require external venting as does propane fuelled
refrigeration. Refrigeration units with DC powered compressors are smaller in physical size because
they do not need the cooling apparatus behind a propane fuelled fridge. Less
heat is generated inside with DC refrigeration. Most people tend to leave their DC
refrigerator running when they leave their cabin or camp. This is because
most with LPG fuelled refrigeration are concerned about running out of propane
fuel when they are gone.
When first turned on DC
compressor based refrigeration cools down faster than propane fuelled refrigeration. A
propane fridge or freezer takes from 4 to 6 hours to come to operational temperature.
Cottagers with solar power and DC refrigeration tend to leave their refrigeration units on all
the time because they don't have to concern themselves with the cost of propane
or running out of propane especially when away from cottage/camp for a week or
more.
You
require a solar system and the associated cost to support DC refrigeration which can be avoided when you
use propane to fuel refrigeration.
