Hello All -
The inside of my shop is approximately 45 degrees F.
I have to go to Florida next week, where it will be 85 degrees F.
Does the 2.2 x to 2.5 x ambient equation work in such a cold shop environment?
If so, do I stop charging at 100 psi to 112 psi on the high side? I have a custom system, so I am unsure the exact weight of the refrigerant required.
Give it a try and record the amount of refrigerant used. It's all going to depend on the amount of hose and the size of the evap and cond? I personally think it is hard to get proper readings in low ambients.
