摘要:
A modular refrigerated structure 10 includes a modular perimeter 12 which defines a refrigerated space 30, a plurality of display openings 24 about the perimeter 12 and at least one personnel access opening 32 for personnel ingress and egress to the refrigerated space 30. Shelves 40 are positioned at each display opening 24 for displaying products. A plurality of roof modules 56 are supported over the perimeter 12 and include a refrigeration module 67, an air passage 60 positioned above a centrally located storage area 38, an air distribution plenum 68 and air outlets 80 positioned adjacent the perimeter 12. The refrigeration module 67 includes refrigeration coils 74 and a fan 72, such that air is moved upwardly by fans 72 from the storage area 38 and into the refrigeration module 67, through the refrigeration coils 74, into the air distribution plenum 68 and laterally outwardly to the air outlets 80 about the perimeter 12 of the structure 10, and then downwardly between the display openings 24 and the shelves 40 for cooling products displayed on the shelves 40.
摘要:
A cooling device with a subcooling system is disclosed, where the cooling device has a closed loop refrigerant cycle containing a refrigerant, including a heat exchanger communicating with the closed loop refrigerant cycle and communicating with a fluid, the heat exchanger configured to selectively receive and cool the refrigerant from the closed loop refrigerant cycle when the refrigerant temperature is greater than the coolant temperature; and a fluid receiving device configured to receive the fluid that is warmed in the heat exchanger. A modular system for providing a refrigerant to a cooling device at an installation location is also disclosed and includes a transportable enclosure having at least one compressor, a condenser and a piping system for conveying the refrigerant in a closed loop cycle, where the piping system includes portions configured to be coupled to the cooling device at the installation location.

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.

摘要:
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.
