Evcon heat pump low temp rise
Posted: Sat Jun 14, 2008 6:12 pm
Hi all,
I was wondering if u could help me with a issue i'm seeing. I installed a new 15 SEER evcon heat pump in my home. I have good cooling but the heat mode is less than to b desired. I checked my pressures and low side is right on. My head is 50-75 psig lower. I have electric supplement heat (2nd stage) I cant seem to get good temp on the suction line.
I went ahead and pulled the R22 from it and did a triple evac on it. (pulled to 500 microns - pressure w/nitrogen and pulled to 500 micron again. 3 times) after this my line temp rose from 109- 120 to 150 - 165. alot better. but i'm worried that the temp rise isn't sufficent. What would a good temp rise for 5 ton system b. what other temps can i look at to b sure. ie amp draw etc. and what do u think the range for those tests should b?
