THE ACTUAL OPERATIONAL SITUATION OF HEAT SOURCE FACILITIES THAT UTILIZED HIGH EFFICIENCY HEAT PUMPS AND THERMAL STORAGE


The Tokyo Electric Power Company’s thermal storage contract service, using
high-efficiency heat pumps and thermal storage, provides for the construction, operation,
management and maintenance of heat source facilities of customer-owned thermal storage
air-conditioning systems. To operate a thermal storage air-conditioning system properly, data
measurement and monitoring are critical for the accurate assessment of operational
situations which will change on a daily basis. Our thermal storage contract service uses
information technology (IT) to acquire operational data, which is subsequently used for
analysis from various perspectives and visualization through graphic representation. Based
on information acquired from analysis and visualization processes, the validity of heat source
facilities is checked daily, and if required, collective measures are taken to achieve optimal
operation. There are many advantages in combining high efficiency heat pumps and thermal
storage, which, when maximized and combined with optimal operation and maintenance
based on operation data, are an essential and effective means of realizing a “Low-Carbon
World” in future.
