top of cavity = just under the lid?
>>>yes
MOD = standard fridge with the "coat" you designed? If not what.
>>>modified lid + coat
RC = you appear to have introduced alfoil but the results are worse???
>>>no, the result is better,the alfoil reduces the radiant energy
Do you have the numbers for a non modified fridge?
>>>yes,I have the figures for the original fridge-lid, there is no significant difference between the RC and the my original.
If the thermostat setting was a constant 5 why is it that the minimum temps vary - doesn't a thermostat always bring the temp down to the same level irrespective of outside conditions? I assumed the fridge would just run for longer until the temp setting for 5 was reached
>>>yes, the switching temperature is unchanged, there is a thermal gradient from top to bottom of the fridge.In my unit the pickup for the thermometeris half way up, it indicates -10c on turn-off.The cooling unit is good, it takes about 30minutes to cool down once stabilised.
In the previous posts I think you did something to the bottom of the lid ie inside the fridge - please clarify what was done
>>>the current moded lid
1. alloy inner shell discarded
2. polyurethane block replaced with 40mm Armaflex ( I had an accident with the polyurethane)
3. a piece of corrugated polycarbonate (Danpalon type) 'replaces' the alloy. This is a food-safe product as it is exposed to the cavity.
You say a 24% reduction in amp hours used - is that simply a factor of less "cold escaping" thus the fridge cycles few times over a given period
>>>yes, exactly!
Re the coat - what is ccf?
>>>closed cell foam
