In recent years, demand for energy-saving operation of individual centrifugal chillers has
been increasing in response to growing requests for the improvement of the energy-saving
characteristics of air conditioning facilities. For this reason, the capability of allowing customers to
be aware of the operating state of the chiller in real time remotely from their offices, headquarters
and other places has been an important need. In order to meet this requirement, Mitsubishi Heavy
Industries, Ltd. (MHI) has developed a chiller operating data browsing system that uses the
ubiquitous Internet environment. This paper presents the developed system.
