NH3 Systems
NH3 Systems
(OP)
Hello there,
I am facing to NH3 Systems
I made a lot of research in internet, in the past threads, but I was not able to find an extremely basic issue: I cannot find any reference concerning the systems utilizing NH3.
Are they utilizing a TXV Valve or are they flooded ?
Could anyone kindly suggest me some literature reference to look into ?
Many thanks

RE: NH3 Systems
Or are you looking at NH3 absorption chilllers?
RE: NH3 Systems
I am looking for NH3 boiling chiller.
At the moment absorption is far !
What I'd like to understand is:
if they work as a freon chiller, they can work either in direct expansion - NH3 enters in the evaporator in a mixture gas-liquid and exits superheated - or in a flooded mode -NH3 enters as liquid and then exits at a certain title but not superheated - can't they ?
Many thanks

It then enters the compressor and then the condenser to complete the cycle.
Look up refrigeration cycle to get more information.
