Hitachi Appliances Launches Exiida Remote Monitoring Service

2018-04-29
At the end of February 2018, Hitachi Appliances announced that intends to provide customers with a valuable new service called Exiida by accumulating, analyzing and utilizing operating data, such as refrigerant pressure, temperature, electric cur-rent, etc. obtained from commercial air conditioning and refrigeration equipment, as well as various other data, such as environmental information, other machines, etc. obtained through the use of the Internet of Things (IoT) technology.
 
The company’s remote monitoring system that has already been provided as a service solution is such that operating data on the equipment is monitored and when problems with the equipment are encountered, the equipment owner or the facilities control office is notified. This time, for refrigeration equipment and chilling units, a sign-diagnosing function is added as an option to the Exiida remote monitoring service, and will be provided as of April 2, 2018. The sign-diagnosing function detects changes leading to problems or breakdown by obtaining normal operating data for a certain period of time based on the operating data collected and comparing them with the operating data of the covered refrigeration equipment and chilling units using local a sub-space classifier (LSC), part of the data analysis technology. With this service, problems or breakdown relating to the refrigeration cycle can be prevented by keeping the equipment in good condition.

Combining know-how and technologies that have been developed from the cocreative project by Hitachi and NTT, Hitachi Appliances along with NTT Data is considering detecting abrasion of bearings used for screw compressors by analyzing operating noise of refrigeration equipment and chilling units, with a view to adding abrasion detection to the Exiida remote monitoring service as a next option.
