Heat Pump Systems Use Wastewater to Lower HVAC Costs

摘要

Philadelphia and Chicago both embarked recently on independent programs to test the effectiveness of using the large volume of waste-water at their treatment plants as a heat source in combination with heat pumps to boost performance of heating and cooling systems. The Philadelphia Water Department and Philadelphia-based Nova-Thermal Energy have partnered to be the first site in the United States to deploy a commercial scale geothermal system that provides building heat using domestic wastewater. In mid-April Novathermal Energy partners, City and U.S. Department of Energy officials held a ribbon-cutting and tour at the Southeast Water Pollution Control Plant where the project has been implemented.
