[tiger1]

need to list in a logical sequence an efficient diagnosis and repair of a fault on a contaminated system in a cold room (forced draft evaporator mounted at height in a cold room with a semi hermetic compressor/condenser unit mounted external to the cold room)
I work with airconditioning and never have i done maintenance on coldrooms:rolleyes: but college insists i gotta do this....

How would you diagnose and repair a fault in an air conditioning system?

It is basic fridge and you need to stop thinking air cond just refrigeration....

Air cond is just refrigeration with bells on :p

So ask yourself :-

What would happen to a system (fridge or air cond) if it was contaminated?

How did it get contaminated in the first place and can that be put right?

How to treat the contamination (does the gas need pulling and replacing,
do dryers need changing, is the comp burnt out, what state is the oil in??? )?

Then HOW do you stop it happening again??

Questions to your quetion but, start right at the begining and work through

What
When
Where
Why
and Who

All the best
