Why not cheap refrig components?

If insulation is really the key to a good ice box to refrig mod, and given that the cost of most marine kits are from 600 - 1000 or more. Why not rig up a way to use a small cheap frig as the source of components and replace the parts every year or two or three.

Meaning, how many $80 refrigerators does it take to equal a $1000.00 kit?

Am I missing something?

Thoughts?

I'm about to go down this path, and maybe post the pics as well...

Re: Why not cheap refrig components?

The $80 refrigerators operate on 110 volts AC. The $600 to $1000 conversion kits operate on 12 to 24 volts DC and pull maybe 3 to 5 amps. The small AC refrigerators pull about 1.25 amps at 110 vac for 137 watts (about depending on power factor) AND then power consumption of the inverter needed to convert 12 VDC to 110 VAC. You are paying for efficiency.

Re: Why not cheap refrig components?

Is that 137 watts per hour, on the AC components?

Plus the power it takes to run the inverter. I don't know how long the cheap
refrigerators run, it depends on the insulation, temperature settings outside and inside in the frig.


"Is that 137 watts per hour,"
Yes if the frig ran for an hour and the inverter was 100% efficient.

Re: Why not cheap refrig components?

I did post recently about how I adapted a $60.00 fridge into my box
I think was " cheap project, let's see them"
Works fine for me since now 4 years

That's on my list. I have some old dorm-style refrigerators in my basement.
