District Cooling
gPotential of District Cooling in India
Submitted by Jyothish Jacob P121031, PGPM (Energy) GLIM Abstract DCS is a highly energy efficient system that provides air conditioning in various zones of the city. DCS cools multiple users through underground piping network applying environmentally friendly energy sources like central chilling plant. Over the past decade, India’s economy has seen unprecedented growth, which has given rise to an increase in energy demand and greenhouse gas (GHG) emissions. The availability of clean and affordable energy and electricity has become a growing concern for the Government of India (GOI), as well as industrial, commercial and residential end-users. DCS has fundamental cost and space saving advantages with energy efficiency, including load diversity, optimized operations, advanced technologies and better staff economies. It adds on extra floor space and enhances aesthetic sense of the buildings. It reduces capital investment required for additional power generation, transmission and distribution infrastructure. There is currently no district heating in India for climatic reasons; district cooling is as yet not in use but holds promise What is District Cooling? District cooling means the centralized production and distribution of cooling energy. Chilled water is delivered via an underground insulated pipeline to office, industrial and residential buildings to cool the indoor air of the buildings within a district. Specially designed units in each building then use this water to lower the temperature of air passing through the building 's air conditioning system. The output of one cooling plant is enough to meet the cooling-energy demand of dozens of buildings. District cooling can be run on electricity or natural gas, and can use either regular water or seawater. Along with electricity and water, district cooling constitute a new form of energy service. District cooling is measured in refrigeration ton which is equivalent to 12000
