Abstract
A refrigeration system includes a low temperature portion with a primary loop that circulates a refrigerant to temperature-controlled storage devices operating at a low temperature, the primary loop also including a condenser to at least partially condense the refrigerant. The refrigeration system also includes a medium temperature portion having a primary refrigerant loop and a secondary coolant loop, the primary refrigerant loop provides cooling to the secondary coolant loop through a chiller. The secondary coolant loop has a first branch and a second branch, where the first branch circulates coolant to temperature-controlled storage devices operating at a medium temperature, and the second branch circulates coolant to the condenser of the low temperature portion.
Claims23
A refrigeration system, comprising:
- a first portion having a primary loop configured to circulate a refrigerant to one or more temperature-controlled storage devices operating at a first temperature, the primary loop also including a condenser configured to at least partially condense the refrigerant;
- and
- a second portion having a primary refrigerant loop and a secondary coolant loop, the primary refrigerant loop configured to provide cooling to the secondary coolant loop through a chiller, and the secondary coolant loop having a first branch and a second branch, the first branch configured to circulate coolant to one or more temperature-controlled storage devices operating at a second temperature and the second branch configured to circulate coolant to the condenser of the first portion.
A refrigeration system, comprising:
- a first portion having a primary loop and a secondary loop operably coupled by a first chiller, the primary loop configured to circulate a refrigerant through the first chiller to provide cooling to a coolant in the secondary loop, the secondary loop having a supply portion and a return portion, the supply portion configured to circulate the coolant to one or more temperature-controlled storage devices operating at a first temperature;
- and
- a second portion having a primary loop and at least one secondary loop operably coupled by at least one second chiller, the primary loop configured to circulate a refrigerant through the second chiller to provide cooling to coolant in the secondary loop, the secondary loop having a supply portion and a return portion, the supply portion configured to circulate the coolant to one or more temperature-controlled storage devices operating at a second temperature;
- wherein 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.
A refrigeration system, comprising:
- a first portion having a first primary loop and a secondary loop operably coupled by a first chiller, the first primary loop configured to circulate a refrigerant through the first chiller to provide cooling to a coolant in the secondary loop, the secondary loop having a supply portion and a return portion, the supply portion configured to circulate the coolant to one or more temperature-controlled storage devices operating at a first temperature;
- and
- a second portion including at least one modular unit containing a second primary loop and a second chiller, the second portion further including at least one secondary loop operably coupled to the second chiller, the second primary loop configured to circulate a refrigerant through the second chiller to provide cooling to coolant in the secondary loop, the secondary loop having a supply portion and a return portion, the supply portion configured to circulate the coolant to one or more temperature-controlled storage devices operating at a second temperature;
- wherein 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.
A refrigeration system, comprising:
- a primary loop and a secondary loop operably coupled by a chiller;
- the primary loop configured to circulate a refrigerant through the chiller to provide a chilled coolant supply in the secondary loop;
- the secondary loop having a first flow path and a second flow path, the first flow path configured to circulate a first portion of the chilled coolant supply to one or more temperature-controlled storage devices operating at a first temperature and to return unchilled coolant to the chiller, and the second flow path configured to combine a second portion of the chilled coolant supply with a portion of the unchilled coolant for delivery as a combined liquid coolant to one or more temperature-controlled storage devices operating at a second temperature.
