Abstract: The present disclosure relates to a method and a system for monitoring health of a refrigeration system. The present disclosure also relates to an Internet Of Things (IOT) enabled method and system for monitoring health of the WIF based on performance parameters like defrost cycle related parameters, defrost cycle duration, schedule and frequency. In one embodiment, the method receives a plurality of real-time temperature data collected by a temperature sensor and determines a steady state value based on the received real-time temperature data. Further, the method computes a plurality of defrost cycle parameter values and generate alarm signals based on deviations of the computed defrost cycle parameters from the respective threshold values. The method generates reports indicating patterns of defrost duration and defrost distribution over a time and provide recommendations to support maintenance of the refrigeration system in response to the deviations.

Abstract: Disclosed herein is method and system for determining energy savings target for distributed sites of an entity. Energy profiles of the distributed sites in a service window are identified. Energy coefficients related to the energy profiles are determined by performing optimization of values of operational parameters of the distributed sites. Energy consumption within the service window is predicted using modular transformation of the energy coefficients. Finally, the energy savings target is determined based on modular transformation of the energy coefficients and current energy savings of the distributed sites. The present disclosure discloses a unique framework for defining a generic set of operational energy savings strategies that are applicable to each type of asset and service window of the distributed sites of an entity.

Abstract: A low noise differential charge amplifier circuit for measuring discrete (e.g., pico coulomb) charges in noisy, elevated temperature and corrosive environments. An input stage of a differential charge amplifier circuit includes a twisted and or untwisted two pair cable with a grounded shield. One twisted and or untwisted pair can be connected to a sensor and a first charge amplifier and a second twisted and or/untwisted pair can be connected to a sensor electrical equivalent impedance circuit and or kept open and a second charge amplifier. The output from the charge amplifiers can be directed to a differential amplifier in order to provide an amplified sensor signal without external noise signal mainly from power supply mains. The differential amplifier and the charge amplifiers can include an auto offset correction circuit to reduce errors due to offsets.

Abstract: A single cell oxygen sensor apparatus and method are disclosed. An yttrium-based stabilized layer having electrical terminals connected to the yttrium-based stabilized layer can be provided on a substrate, wherein the yttrium-based stabilized layer is excitable by a constant current applied to the electrical terminals. A plurality of electrodes are located on a side of the yttrium-based stabilized layer and a plurality of heater elements located on said substrate opposite said yttrium-based stabilized layer. The heater elements can maintain the yttrium-based stabilized layer at a particular temperature. A cavity is formed and located between the yttrium-based stabilized layer and the heater elements. The partial pressure of oxygen can be measured by comparing the partial pressure of oxygen within the cavity with respect to the partial pressure of oxygen in the atmosphere external to the single cell oxygen sensor apparatus.
