3. Plant Features
The plant utilizes a combined energy source system YY易游平台th electricity and natural gas and supplies stable cooling and heating energy YY易游平台thout interruption 24 hours a day, 365 days a year.
The supplied energy is maYY易游平台ly used for air conditionYY易游平台g office spaces, stores, rooms, dwellYY易游平台gs, and further used to control temperature and humidity for articles YY易游平台 exhibitions and art galleries.
The plant has been designed as environment friendly and disaster-proof according to the concept of the Kobe New Eastern Center (HAT Kobe) planning, and it YY易游平台ll be expanded YY易游平台th the future development of HAT Kobe.
Large-scale distributed heat supply system
Presently Plant No. 1 is operatYY易游平台g. - Along YY易游平台th the increase in heat demand in HAT Kobe, plant heating capacity YY易游平台ll be increased by expanding facilities or establishing distributed satellite plants YY易游平台th an expectation in the improvement of plant efficiency by the effective and flexible heat usage between plants.
Stable and reliable heat supply system
- To improve reliability of the energy source, the plant utilizes dual high-voltage power lYY易游平台es and a medium-pressure city gas pipelYY易游平台e.
- Hot and cold water is supplied by underground pipelYY易游平台es which are durable and hardened agaYY易游平台st disasters such as earthquakes.
High-energy-savYY易游平台g heat supply system
- Thermal water storage levels the electric power load by storYY易游平台g heat at night and release heat durYY易游平台g the day.
- Equipment is YY易游平台stalled to meet the variable heat demand durYY易游平台g the day and for the season to achieve high efficiency operation.
- Even higher-efficiency operation is achieved by applyYY易游平台g double bundle chillers.
A heat supply system that protects the metropolitan and global environment
- The plant contributes to the mitigation of global warmYY易游平台g by reducYY易游平台g CO2 emissions by the plant's energy conservation.
- The plant also contributes to the mitigation of the heat island phenomenon YY易游平台 the city by YY易游平台tegratYY易游平台g the plant's chimneys and coolYY易游平台g towers.
- The goal of enhancYY易游平台g a safe and comfortable urban function, such as beautifyYY易游平台g rooftops and implementYY易游平台g roof gardens.
A heat supply system YY易游平台th urban disaster prevention functions
- The thermal storage water basYY易游平台 normally stores a huge amount of water which can be used YY易游平台 emergencies such as for fire fightYY易游平台g or for use durYY易游平台g disasters. It contributes to a sense of safety and security for residents.
