Re: sight glass
Hi Bernard,
I cant think of a purely technical answer but perhaps its so there is then no possible restriction of liquid from then on till the evaperator. Obvioulsly if the drier was blocked and the sightglass was before it the then drier could show liquid in it but because of a blocked drier the liquid would not get to the coil.
Regards
Raymond.
PS Anyone out there work for Capital Cooling ?

Re: sight glass
Yes seems so obvious now, if the drier was blocked the sight glass would still show full.

Re: sight glass
Hi Bernard,
Sight glass should show the flow and if equipped, also if the liquid is wet or dry.
It is installed after the drier in case the drier is partially blocked,
Then you see the white bubbles but to make sure drier doe's not function right, feel it, if cold = blocked, if warm = sortage of gas.

Hi chemi
Also a blocked condenser for a warm drier.So what is the next oldies then,I have noticed on the old celler cooling units I replaced there is some sort ot oil trap fitted a couple of meters before the evap is this an oldie as the new units don,t need them.

Re: sight glass
Hi Bernard,
Good luck with the supermarket work, you could have picked a better time to go into it though !!!!!. It's not bad work if you have the time, very demanding but the benifits are there for those that stick with it.

Re: sight glass
The Prof, of course, would approve installation of a sightglass/moisture indicator before and after the filter-drier, allowing one to cover all bases...

Re: sight glass
Drier will also keep sightglass clean if before it.
