12. Industrial Refrigeration Control Development

13. Initial offering involved stand alone units

15. Sales meeting with another large corporation

16. They indicated that they were satisfied with the operation of their PLC based controls.

17. At that time, we had a system that was best suited for systems without viable automatic controls.

18. We agreed that a system that combined their PLCs with our algorithms might be a good platform.

19. We were given a relatively new plant in Maine to use for TC I prototype development along with their technical assistance.

46. TCI does not replace the existing system, it complements it.

47. The PLC still provides basic control, the TCI provide the optimization.

48. Why can’t the PLC design be upgraded to perform the TCI tasks?

49. The TCI provides control algorithms and speed that is not possible within the PLC environment.

54. To allow each controls component to operate where it fits bestThe PLC to do the basic house work and alarming. The TCI to determine the higher end control and to indicate the results to the PLC for final I/O (Input/Output) control.

56. TCI’s Energy Consumption Advantages Compressor Optimization Control

58. For this reason, when a variable speed device is available, it is prudent to operate it as the trimming machine as much as is possible.

59. TCI will accommodate this by determining which compressors (based on capacity) should be turned on and off in order to attempt to keep the variable speed compressor within its 50% to 100% range.
