Hi effieciency dx units
Hi effieciency dx units
(OP)
Could someone please explain how a hi effieciency dx split system is designed? Does a 4 ton 10 seer remove the same amount of latent and sensible as a 4 ton 13 seer? Is the volume of air the same for both units (2000 cfm).If I am considering replaceing my 4 ton unit with a higher efficiency unit will I have humidity problems? I know higher efficiency means the same 4 tons cost less to operate, but what is the sacrifice or is there any?
Thank you
Thank you

Generally scroll compressors consume less power when compared to recips and most of the high EER(or SEER) units have these. Further, a 4 row coil condenser unit gives better performance at higher ambient temperatures and the compressor discharge pressures are lower when compared to a 2 row coil.

Not so the evaporator side...Humidity is going to be effected, a large evaporator will operate at a higher suction with the same airflow, which without getting into copious detail will be accompanied by a lower dew point depression and that is largely the need in a HH A/C System
There are some who opt for 6-ton units on a 3-ton load...Effectively, the unit cycles such that it only operates 50% of the time even when its hot & humid...The interior space then goes from humid, to just a little less humid, and back to humid...And people then set the T-Stat for 64 so the damn thing has a chance to dry out the space.
And you SEER don't mean much if your unit is running 100% of the time and your living room is cold enough to age steaks...
