Nice animation of refrigeration cycle

[cool runings]

hi there thanks for the reply, thank u i inderstand it better now so a low hp would hinder the chances of oil returning to the compressor as the differential pressure would become lower?

thanks for the replies guys

Yes and no.

There are different ways of delivering oil to the comp.

If it is directly delivered then the differential pressure need only be 1 bar and it would still flow the oil. Pressure always flows from high to low.

Some more complex systems restrict the pressure through regulating valves and these are set to be about 5 bar above crank pressure.

There are other ways but the pressure will always be higher in the discharge.
