Abstract—In this study, the performance of a wastewater heat pump system, which was designed and installed in Izmir, Turkey, is experimentally assessed. The wastewater temperatures utilized are about 9-14oC and 26-29oC in winter and summer seasons, respectively. It may be concluded that a wastewater source heat pump is more efficient than an air source heat pump in Izmir, Turkey, of which western coast has a Mediterranean climate. According to the results, by using wastewater source heat pump can provide heating and cooling efficiency up to 44% because of lower condensing and higher evaporation temperatures. Also wastewater source heat pump can use bigger portion of theoretical energy potential than air source heat pumps.
Index Terms—Energy efficiency, heat recovery, sustainability, wastewater, wastewater source heat pump.
