District Energy System (District heating, District Cooling) for distributing energy generated in a centralised location (1).

District cooling (2) 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 (3) (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.
