Hi
I have a Waeco portable fridge (the type that uses gas/12/240V) however the output never seems to be that great.
I believe the unit is a atriple fluid device ammonia/water/hydrogen system that is sealed for life.
I have tried the usual tricks such as turning it upside down and always make sure that it is level.
I have done a bit of research so am fairly comfortable of the basic principles but I have struggled to get the unit to increase its performance.
I have tried increasing the thermal input (by running 12V and 240V elements concurrently)
I have tried increaseing air flow across the rear of the unit (mainly directed at the ammonia condensor).
It appears that there is something more to the technology than I first thought!
Can anyone offer any advise as to how I can increase the thermal cooling capacity of this fridge?
Once the boiler/generator goes above a certain temperature does it not increase the the amount of ammonia boiled off thus the cooling capacity of the system - or does it just increase the overal pressure in the whole system and consequentially increase fluid boiler temperatures which is the limiting factor.....
Any knowledge or advise appreciated.
Thanks in advance
