R134A Running Pressures
Hi
Apologies if this is in the wrong thread!
We have been asked to look at a walk in freezer operating on on R134A i have never been to look at a freezer running on R134A what sort of running pressures should i be looking for to get the freezer down to -18oC? Currently the freezer is only achieving around -8oC
Am i right in thinking the suction should be around 1psig?
Thanks in advance for any help
