Project: District heating and cooling for the Olympic Village
Comission: System design
Client: Beijing Tianyin Geothermal Development Co, Ltd
Year: 2005, commissioned summer 2007
Capacity: 30 MW cooling, 20 MW heating
Our first commission in China was a system design, including investment budget estimation, of a centralized heating and cooling system for the Olympic Village in Beijing. The task was to create an economic system characterized by an environmental profile.
We have designed the system with heat pumps using treated sewage water as a low-temperature energy source. The sewage water is taken at 3 km distance from the Village and distributed by a newly built pump station. The production plant in the middle of the Village delivers heating and cooling energy to apartments. During summer one heat pump is used for covering hot-tap water load, and the others – only cooling. The sewage water is utilized as a heat sink in this case, i.e. it removes condensers waste heat.
The project pre-design was quite detailed and included the whole thermal energy system: pump station and sewage water piping, production plant, distribution networks and also terminals in the apartments.
The system was in operation before summer 2007 in order to be tested well in advance before the summer Olympic Games 2008.
