| 20110304466 | Refrigeration System Management and Information Display - Embodiments of the invention provide methods of displaying information associated with a refrigeration system, methods for managing a refrigeration system, refrigeration systems, methods of providing redundancy to a refrigeration system, and injector systems. A refrigeration system and method for displaying information associated with a refrigeration system includes monitoring a temperature associated with the refrigeration system, detecting events associated with the refrigeration system, and displaying the temperature and at least one event associated with the refrigeration system occurring during a predetermined period of time, including displaying the temperature occurring during the predetermined period of time and displaying a user interface element associated with at least one event occurring during the predetermined period of time. | 12-15-2011 |
| 20110302936 | REFRIGERATION SYSTEM HAVING A VARIABLE SPEED COMPRESSOR - A two-stage cascade refrigeration system is provided having a first refrigeration stage and a second refrigeration stage. The first refrigeration stage defines a first fluid circuit for circulating a first refrigerant, and has a first compressor, a condenser, and a first expansion device that is in fluid communication with the first fluid circuit. The second refrigeration stage defines a second fluid circuit for circulating a second refrigerant, with the second refrigeration stage having a second compressor, a second expansion device, and an evaporator that is in fluid communication with the second fluid circuit. A heat exchanger is in fluid communication with the first and second fluid circuits to exchange heat between the first and second refrigerants. At least one of the first or second compressors is a variable speed compressor. | 12-15-2011 |
| 20110259038 | Modular Cabinet For Ultra-Low Temperature Freezer - A storage cabinet ( | 10-27-2011 |
| 20110072837 | REFRIGERATION SYSTEM MOUNTED WITHIN A DECK - A refrigeration system is provided for use with an ultra-low temperature freezer having a deck and a refrigerated cabinet supported above the deck. The system has a first refrigeration stage and a second refrigeration stage. The first stage defines a first fluid circuit for circulating a first refrigerant. The first stage has a first compressor, a condenser and a first expansion device that is in fluid communication with the first fluid circuit. The second stage defines a second fluid circuit for circulating a second refrigerant. The second stage has a second compressor, a second expansion device and an evaporator that is in fluid communication with the second fluid circuit. The system includes an insulated enclosure supported within the deck and a split-flow heat exchanger that is in fluid communication with the first and second fluid circuits and which is located within the insulated enclosure. | 03-31-2011 |
