Hello everyone, Just new to the site and have alot of questions. (A) What is the effect of subcooling in relation to part load and full load, low ambient operation with a heli-rotor style or unloading piston compressor. What is the relation to part load, normal ambient operation at part and full load. I would think the load on the evaporator and position of the metering device would have some input on subcooling. Does subcooling rise or drop toward saturation in the condenser. (B) What does the effect of a liquid receiver have to subcooling down stream of the receiver, Would there be subcooling? Or since the reciever would have two phases the receiver/liquid line would be at saturation? Is that why alot of places use LPA pumps after the receiver to make sure subcooled liquid gets to the metering device.
