On a 90 degree DAY,should the discharge air from condenser fan be 30 degrees above ambient temp.(120)Anything less would mean dirty outside coil?

True or not. | The more dirty the coil is the higher the temperature will be. 20 degree rise is considered ideal. |  02-21-2012, 08:57 PM | Professional Member | | Join Date: Jan 2001 Location: Nebraska Posts: 270 | | Chart that I Use.

I use my pressure to let me know if my coil is dirty __________________ Life would be a lot easier with honest co-workers and without back stabbing!

Is to go by how the unit is running, SH, DT, pressures. If the unit is running as designed based on the running specs. cleaning a coil will not make it run any better. but as a rule 10 to 20 Diff. is what i have used as a quick check |  02-22-2012, 07:23 AM | Regular Guest | | Join Date: Feb 2012 Posts: 9 | | 30* for r22 and 20* r410a? |  02-22-2012, 07:27 AM |  | AOP Committee/Professional Member* | | Join Date: Sep 2008 Location: somewhere between Raising He*l and Amazing Grace Posts: 14,298 | | Quote: Originally Posted by alex13177 30* for r22 and 20* r410a? | Refrigerant doesn't matter. |  02-22-2012, 07:50 AM | Regular Guest | | Join Date: Feb 2012 Posts: 9 | | Quote: Originally Posted by jpsmith1cm Refrigerant doesn't matter. | you are right, I was thinking something else.

Also low air flow (dirty coil, filter blocked return, blower running too slow) can cause the OD coil to bee cooler than expected. | Thread Tools | | Display Modes | Linear Mode | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | |
