Hi everybody,
I have a project for freezing foods
this are the loads:
660 kW at -45 ºC evaporating temperature
600 kW at -28 ºC evaporating temperature
No load for -10 ºC
I was thinking first about two separate 2 stage systems with ammonia 4:1 (cold rooms).
But I was told that this could be afford with some screws and economizer, only one stage compressors? :confused:(If I remember).
I have seen some drawings in different threads (thank you Josip and US Iceman):D
But I have problems to adapt them to my needs.:cool:
I know that cascade nh3/co2 could be a good option but I prefer think about it later.
My question is if someone could give some explanations or drawings for a system that could achieve this with good technical aspects (optimization, reduced electric consumption...) and without a too large initial cost
Thank you in advance!
There's so long way to come...
