hey fellas been working on a system but want to give you fellas a few figures and see what you guys think! Model number as above and on R407c,4.3kg

Heat mode

Discharge pressure=16 bar
Suction pressure=2.5bar
Air on evap= 17.0
Air off evap=30.5
Air on condenser=2
Air off condenser= 0
Temp going into evap=56 deg c
Temp out of evap= 24 deg c
Temp going into expansion valve=24 deg c
Temp out of expansion valve=7 deg c
Temp into condenser=7 deg c
Temp out of condensor= 2 deg c
Suction into compressor= 3 deg c


cooling mode

Discharge pressure=12 bar
Suction pressure=3 bar
Air on evap=18 deg c
Air off evap=6
Air on condenser=20 deg c
Temp going into evap= -2 deg c
Temp out of evap= 5
Temp goin into expansion valve= 27 deg c
Temp out of expansion valve= -2 deg c
Temp into condenser=57 deg c
Temp out of condenser=27 deg c
Suction into compressor=9 deg c

much appreciated

What do you want to know?

[TRASH101]

You got a lot of superheat at the comp suction in cooling mode are you sure that the system was in stable operation when you took the measurements

Airconadam,

Does the unit have a fan speed controller option installed? The min operating range (ambient temp) in cooling is 20 C without HPC.

hi yes the outdoor did have a fan speed controller but was only coming on every 10 secs and then stopping and continue to do so,I thought due to the low head pressure? it was set to the auto position.We have been having problems with this unit with it going off on hp but only on heating? I think possibly an airflow problem. thanks alot
