Energy Efficient Pumps and Pump Solutions for District Cooling PROVEN TECHNOLOGY DESMI

District cooling follows a simple process: • Water is chilled at a central cooling plant (or taken from the sea). • Chilled water is pumped through a network of underground pre-insulated pipes to customers’ buildings. • An air-conditioning water system inside the customers’ building circulates the chilled water. • Air is then pumped through the chilled water piping of the airconditioning system producing cold air. District Cooling is 40% - 60% more energy efficient than conventional systems – and reduces CO2 emissions. If District Cooling were to expand to 25% of the cooling in Europe,...

District Cooling District Cooling is an efficient and environmentally friendly utility service, which provides chilled water from a centralized cooling plant (or cold water from the sea) through a network of pipes to multiple residential, industrial and commercial buildings for air conditioning purposes. District Cooling is simple and clean. It creates a cool, efficient indoor climate, without the need for bulky refrigeration equipment and noise in or near residences. The supply is assured year-round with minimal maintenance needed, which is reflected in reduced operating costs and lower...

Copenhagen, Denmark - Case Story HOFOR has the English name “Greater Copenhagen pumps due to supplying marine pumps for moer Utility”. than 100 years. District cooling concepts with HOFOR: • In the winter months, production of cooling is by seawater, which is brought into the cooling system by a pipeline from the harbour. Production is totally free of CO2 emission and is called free cooling. • The seawater is not cold enough in the summer months to cover the whole cooling demand. Therefore, surplus heat is used to produce cooling as well. This method is called absorption cooling. • A...

NUON Energy - Case Story Nuon, part of Vattenfall, is a leading energy company that generates electricity and produces gas, heating and cooling, which it supplies to approximately 2.2 million households, companies and organizations in the Netherlands. In 2009 DESMI supplied some of our energy efficient pumps to Nuon for a district cooling project in the south area of Amsterdam. Capital Cooling from Sweden did the engineering. The DESMI pumps supplied (NSL 300/525/A02-I complete with 630 kW 3 x 690 Volts 1800 rpm e-motors) are used to distribute lake water to the heat exchangers in the...
