Re: Is a Fridge Colder on AC or DC ?

Agreed, refrigerators are as cold as where you set the thermostat.

Are you meaning to ask if AC or DC motors are more efficient or if AC or DC power is more efficient?

Re: Is a Fridge Colder on AC or DC ?

I have a Waeco portable refrigerator/freezer and it is considerably colder on AC than on DC. The normal setting when used on DC is 4. When plugged directly into AC it freezes the contents. The temperature drop has been measured at 38 degrees F on DC and 32 degrees on AC. The thermostat setting has nothing to do with the power change.

Strange. I have an old Engel which works exactly the same on either AC or DC. In fact I believe that it has a transformer/rectifier built in, so in reality it is always running on DC regardless of where it's plugged in.

Other way around, but precisely.
