OT - What Is A Good Rule Of Thumb For Charging R22 In My Central A/C?
I have a small leak in my evaporator. So, here comes the cooling
season again, and until I have the money to get the system repaired, I need to add a charge. I've got the gauges hooked up, and measured the ambient temperature at 82 deg F. I remember that I used to just subtract x deg. from the ambient, and add refrigerant until I reached that value on the low-side gauge. However, I don't remember what that value is. IIRC, it was 35 or 40, but the synapses don't fire like they used to. Can anyone help me out here? I fail to understand the superheat/subcool stuff, but the rule-of-thumb has served me well in the past. Joe |
