zerol ice reducing system capacity
I got a call on a one and a half ton trane split system heat pump, that may be undersized for the space and that was the reason for the call.while I was there I recorded the following readings:
suction-85 discharge-190 sh-20 sc-2 indoor wet bulb-71 outdoor dry bulb-87 indoor dry bulb-81, delta t across evaporator-14 delta t across the condenser- 8
the thing that seemed not right with this system was the low condenser split (condenser coil was clean and the head pressure is normal),and that it took nearly 30 minutes of run time for the superheat to come down and the evaporator to start to produce condensation.
when the system was install someone put zerol ice in the system, and I was wondering if anyone has had experience with this, and was also wondering if this was what took the system so long for the superheat to come down. i have never used this product, and am thinking that this may be effecting this system's performance or am I overlooking something here
