Abstract
A refrigeration system includes a first portion having a primary loop and a secondary loop operably coupled by a first chiller, The primary loop circulates a refrigerant through the first chiller to provide cooling to a coolant in the secondary loop. The secondary loop has a supply portion and a return portion, the supply portion circulates the coolant to one or more temperature-controlled storage devices operating at a first temperature. A second portion has a primary loop and at least one secondary loop operably coupled by the second chiller. The primary loop circulates a refrigerant through the second chiller to provide cooling to coolant in the secondary loop. The secondary loop has a supply portion and a return portion, the supply portion circulates the coolant to one or more temperature-controlled storage devices operating at a second temperature. The return portion of the secondary loop of the first portion and the return portion of the secondary loop of the second portion share a common return header.
