District heating
A system where various types of heat source equipment produce heat transfer media such as chilled water, hot water, and steam, and this equipment is centrally managed from a heat supply plant. The plant supplies the heat transfer media to buildings within a specific area using local pipelines, providing services such as cooling, heating, and hot water supply. Since there is no need for each building to have its own heat source equipment, the system allows for high-efficiency operation. It also enables the use of renewable energy sources that are difficult to utilize in individual buildings, thus achieving energy savings and reducing environmental impact.
