client: Regional Municipality of Sudbury
location: City of Sudbury - Sudbury Sewage Treatment Plant
project description:
R.V. Anderson Associates Limited designed an energy efficient heating system for the Sudbury Plant's new Chlorine Storage and Handling Facility by utilizing the plant's effluent water as a heat source. Filtered effluent water is available 24 hours a day for process use and clean up. Multiple Water Source Heat Pumps are used to extract heat from effluent water by lowering the temperature through a refrigeration cycle and re-using this heat for building heating. By selecting units with reversing valves in the refrigerant system, the pumps provide cooling in the summer by rejecting building heat to the water. The schematic drawing above shows the principal components of the system. When no effluent water is available, the system switches automatically to electric heating. |
