Centrifugal chillers are mainly used as heat sources for factory air conditioning and district heating and cooling system. As with residential air conditioners, the electricity costs account for a large portion of their operating costs, so energy saving is important. However, it is not easy for customers to correctly monitor the equipment status and improve energy efficiency on their own. Furthermore, As the machine ages, it is more difficult to keep track of maintenance records, which makes it even harder to perform effective maintenance. To solve these problems, Mitsubishi Heavy Industries Thermal Systems, Ltd. (MTH) has launched a portal site which helps our customer s to easily access to machine specifications, recommended maintenance plans and records, as well as real time chiller operation status when necessary. In addition, by integrating the portal site with the introduction of IoT to centrifugal chillers, MTH have visualized energy efficiency and loss, and have started to provide solutions for realizing data-based energy saving.
