This is an extract of an article in the latest ACHR news.
‘…Often a receiver bypass will be used so the subcooled liquid will not sit in the receiver and lose it’s subcooling. This bypass simply bypasses liquid around the receiver and directly to the liquid line and filterdrier. A thermostat with a sensing bulb on the condenser outlet senses liquid temperature coming to the SV. If the liquid is pre-cooled to a predetermined temperature, it will be bypasses around the receiver..”’

My comment on this: ‘Often a bypass will be used…’ I never saw this in my life and read never of it in books. What will happen if the system has long lines and the TEV’s closes partially due to reduced load? The liquid will build up in the condenser.

Second comment: you can’t measure subcooling with only a thermostat. You need at least two thermostats or even better a press-stat and a thermostat.

What do you guys think of this?
