Anybody have any experience with a Copeland easycool condensing unit??
The unit contains two copeland scrolls with an Emerson EC2 511 controller.
x4 supermarket freezers are fed from this unit.
Basically the freezers are hovering around -15 degrees rather than below the -18 critical temp.
Condenser was quite dirty so I blew out the coils with nitrogen.
Saturation temperature on low side is 15 degrees/2.5bar which seems quite high for a freezer, discharge pressure is around 16bar.
What kind of head pressure/suction pressures does this unit operate under? There is 2 condenser fan motors with only 1 currently running but I am unsure as to the pressure that the second one kicks in.
