Abstract: A system includes a compressor temperature sensor that generates a compressor discharge temperature signal corresponding to a compressor of a refrigeration system, a compressor pressure sensor that generates a compressor discharge pressure signal corresponding to the compressor, and a controller processing the signals over a predetermined time period. The processing includes calculating a discharge saturation temperature based on the compressor discharge pressure signal, calculating compressor superheat data based on the compressor discharge temperature signal and the discharge saturation temperature, accumulating the compressor superheat data over the predetermined time period, and comparing the accumulated compressor superheat data to a predetermined threshold. The controller generates an alarm indicating a compressor fault based on the comparing.

Abstract: A system is provided for monitoring the food product of a remote food product retailer. The system includes a management center in communication with the remote food product retailer via a communication network. The communication network is accessible via a user interface that may be located at any of the management center, the remote location or some other location. The management center gathers food product temperature information and uses that information to determine whether the shelved food product is within acceptable food safety and quality limits. If the food product exceeds these limits, an alarm is sounded at either the management center and the remote location. The user interface is operable to monitor the status of the food product via a selection of screens and remotely respond to the alarms.

Abstract: A controller comprises a first input that receives a signal indicating an energy consumption value of a compressor, a second input that receives a signal indicating an energy consumption value of a condenser fan, and an output that provides a control signal to the condenser fan. The controller also comprises a memory that stores a condenser set point, and a processor in communication with the input, output and memory and that modulates the condenser set-point to minimize energy consumption and controls the condenser fan based on the condenser set-point.
