Parallel racks are large refrigerant charge central compressor systems located in a machine room.		These units are smaller parallel compressor systems located in close proximity to the refrigerated loads.
These systems utilize heat transfer fluids that are pumped around the store from the backroom (sometimes called “chillers”).		Condensing units are single compressor systems with a condenser coil, used for individual cases or line-ups of walk-in coolers or freezers.
