Fault Detection and Diagnostics for Commercial Coolers and Freezers
نویسندگان
چکیده
Most of the previous diagnostics research for vapor compression equipment has been performed for packaged air conditioners and chillers. This paper describes application of a decoupling-based diagnostic technique that was originally developed for air conditioners to equipment used in walk-in coolers and freezers. Testing was performed on a small, restaurant-style walk-in cooler and a small walk-in freezer for faulted and un-faulted conditions. The data was then used to characterize how the fault features respond to faults and to evaluate the performance of the decoupling-based diagnostic technique.
