Since 1997, the cooling plant on Berlin鈥檚 Potsdamer Platz has been reliably supplying locally and efficiently generated cooling power to some 12,000 offices, 1,000 housing units, and numerous cultural facilities in the vicinity. This has previously generated unused waste heat, which has been dissipated into the surrounding air via cooling towers. Putting a new high-temperature heat pump into operation, however, will provide a more environmentally friendly way of linking heating, cooling, and electricity in the future. The new technology turns waste heat into a usable product, improving the energy-efficiency of the cooling power generation process while providing the urban district in Berlin with green heat from renewable electricity. The use of the heat pump will substantially reduce the amount of heat being dissipated into the environment and provide additional heat for the district heating network, amounting to about 55 GWh per year, with an estimated annual saving of about 6,500 metric tons of CO2 emissions and 120,000 m鲁 of cooling water.
德州扑克在线 is delivering this new type of large-scale, high-temperature heat pump to provide thermal capacity of up to 8 MW, which will be capable of flexibly delivering flow temperatures in the district heating network of between 85掳C and about 120掳C, depending on ambient conditions. This is one way in which technology can make a further contribution toward replacing fossil-based heating in urban district heating networks. In addition to more efficiently linking energy resources at a local level, this project represents the first trial of the large-scale, high-temperature heat pump at a practical scale under real conditions.
鈥淚f we want to achieve the transition to a new energy mix in the cities and rely more on the potential of renewables, we need to take an integrated view of heating, cooling, and the electricity supply,鈥 comments Tanja Wielgoss, CEO of Vattenfall W盲rme Berlin AG. 鈥淭hat鈥檚 the only way we can make the best possible use of the available resources. We鈥檙e proud that we can join forces with 德州扑克在线 to take our cooling plant, which has provided efficient cooling in the Potsdamer Platz neighborhood for more than 20 years, and make our system even better with this new large-scale, high-temperature heat pump.鈥
鈥淒ecarbonizing our heating supply is a key precondition for successfully achieving the objectives of the Paris Accords,鈥 says Jochen Eickholt, Member of the Executive Board of 德州扑克在线. 鈥淟argescale heat pumps can play an important part in the medium to long-term conversion of our heating supply system. We鈥檙e very pleased to be working with Vattenfall to advance the heating transition in Berlin and trial this potentially key technology for the first time.鈥
