Hi
hope you can help. I would like to learn about NH3 systems.
can anybody point me in the right direction to some 'typical' system designs and maybe a not too heavy paper on the basic differences between NH3 and HFC or CO2 systems? i've never had to/wanted to work on a system yet but i've seen the rapid growth of CO2 over the last few years and now everybody tells me that NH3/CO2 cascade is the best possible solution for the future.
Any help would be great
