  1. OP1>Constructor 1 says NH3 is the best
  2. OP2>Constructor 2 says NH3/CO2 is the best

So our question is which one is the best in your eyes?
1: Energy consumption >OP1
2: Maintance.>OP1
3: Difficulty to control the system> Unknow
4: Environment problems > None
5: Building Difficulty for the constructor >OP2
6: COP : OP1
7: Safety for products and employers. > OP2
8: Durability >OP1
9: Suction or screw compressor : What do you mean?
10: Which system has the best build to upgrade in a later stadium? OP1

Since contractors emit unsubstantiated opinions, I guess my opinions for or against either require no sustain (although facts exist).
I think that the best choices favor the Contractor 1 in 5/2.
