The Fridge was adopted from a cabin
up in Shawnigan. The donated 'Hudson Bay' company fridge
had put in its time and was lucky to move onto such a prestigious
honour as becoming the ultimate drink fridge.
The fridge started of as a stand alone circa 1960’s
Hudson Bay harvest gold refrigerator/freezer. Sir Mix-A-Lot
did not require a sub zero operating temperature – in
fact this would be detrimental to some of the liquids
inside, due to freezing. Sir Mix-A-Lot also required
a substantial amount of room. The constraint led us to
removing the barrier between the fridge and the freezer.
The vegetable crisper at the bottom of the fridge was
also removed to increase the usable area inside the fridge.
Hole in Bottom of Fridge
Sir Mix-A-Lot requires access for communication and
supplies. To keep that aesthetics of the fridge, it was
decided to route these lines through the bottom of the
fridge. This allowed us to connect the pumps to the external
circuitry, as well as supply power to the carbonator.
The carbonator also required a pressurized water inlet
as well as a CO2 line. The only other thing
that needed to be routed though the hole was the connection
LCD mounted in the freezer door.
The insulation was changed from a fiberglass to Styrospan
This was done for two reasons: safety and thermal reasons.
The Styrospan was safer to handle and manipulate that
the fiberglass since there where no glass partials. The
Styrospan also hand a higher thermal temperature coefficient.
After changing the insulation inside the fridge doors
the back covers to the doors where changed to aluminum
sheeting. This gave the fridge a cleaner look when the
doors where open.
The fridge was also painted a flat black for esthetic
reasons. This was done using spray paint due to its ease
in covering an area such as the outside of a fridge.
Spray paint also has a fairly decent look when it has
been done correctly.
The LCD needed to be mounted at a height such that it
was easy to use. It was decided that mounting the LCD
in the freezer door would get this result. It would be
directly at eye level so that it was easy to read. This
also was right put the user right in front of where the
drink would be dispensed.
The LCD required that a hole be cut in to the front
of the door of the freezer. After this was done the LCD
still needed to be mounted in such a way that people
would be able to press on it with a substantial force
with out moving it or breaking it. This needed to be
done inside the freezer door. Two vertical bars where
mounted on the back of the LCD and then the bars where
attached to the edge of the freezer door.
Moisture is a concern when ever working with expensive
electronics. The cords from the LCD needed to be run
inside the fridge and out through the hole in the bottom
of the fridge. This meant that there was a hole through
the flashing on the back of the freezer door. This could
potentially allow moisture to condense on the LCD – damaging
it. To solve this problem a vapor barrier was created
between the inside of the fridge and the LCD.
