Dear friends,

I have a doubt regarding the capacity of compressor and the fixing of suction temperature. If we are having a plus temperature (say 1 degree celsius as suction) system with an economizer in it , the system is normal.

If we have to make it for negative application say -10 deg C then what is the procedure simply adding a Expansion valve in between the exact place of the system give you the temperature or any other changes has to be made.
