Question about refrigerant charge
Hi All,
Would you please someone let me know :
Why when temp. of evaporator is low we must charge system with more refrigerant.
For example if a system working on air-conditioning system we must charge system with less refrigerant instead if that system works for example on -15C evaporator temperature.
Sincerely yours.

I'm not sure what's the science behind it, but I've been always told to do so.
Re: Question about refrigerant charge
Any system, high temp (A/C) or low temp should be charged to the correct suction superheat.
Different types or sized systems will have different charge amounts
Re: Question about refrigerant charge
AC system will not operate well in low evaporating temp. You need a low temp compressor for that.
