Suction valve position when set point is reached ?

Thanks for this answers .

I just wanted adder opinions. Some conclusion will be:

1. When it closed, then compressor work less because refrigerant is not emptied from evaporator, but GPLX (PMLX or ICLX) work harder and can break more frequently. Temperature control is more precise.

2. When it open, everything opposite then stated by 1.

to some degree.

if the valve stays open on reached set point, the compressor really wouldn't work any more than it should because the room is at temperature. if you stop the fans there would be no heatload on the cooler.

if you close the valve there is going to be pressure buildup in the cooler and when the valve opens it's going to cause a surge that the compressor can't keep up with, and it's going to have to work harder to get the pressure back down.
as opposed to keeping the suction valve open, there wouldn't be any significant surge when the liquid valve opens, and so the compressor will have an easier task of maintaining the suction pressore.
