District Energy System (District heating,
District Cooling) for distributing energy generated in a centralised location. District cooling is cooling generated in special place or plant
instead of each building having its own cooling plant. District cooling is
based on cold water being distributed in a network of pipes in the same simple
ways as district heating. Water is cooled and feed through a network of pipes
to residential buildings, offices, hospitals, industry and used to cool the air
circulating in the properties’ ventilation systems. The same water is then fed
back to the production plant to be cooled again. District heating (also
known as heat networks) is a system for distributing heat generated in a
centralised location for residential and commercial heating requirements such
as space heating and water heating. The heat is often obtained from a
cogeneration plant burning fossil fuels but increasingly also biomass, although
heat-only boiler stations, geothermal heating, heat pumps and central solar
heating are also used, as well as nuclear power. District heating plants can
provide higher efficiencies and better pollution control than localised
boilers.
