There is a strongly growing interest for wastewater heat recovery (WWHR) in Sweden and elsewhere, but a lack of adequate tools to determine downstream impacts due to the associated temperature drop. The heat recovery potential and associated temperature drop after heat recovery on a building level is modelled for a case study in Linköping, Sweden. The maximum temperature drop reaches 4.2 °C, with an annual recovered heat of 0.65 kWh · person · day. Wastewater temperature out from the heat exchanger was 18.0 °C in winter at the lowest. The drinking water source type can be an important factor when considering wastewater heat recovery.
瑞典和其他地方对废水热回收（WWHR）的兴趣日益浓厚，但由于相关的温度下降，缺乏足够的工具来确定下游影响。对瑞典林雪平的一个案例研究进行了建筑物层面的热回收的热回收潜力和相关的温度下降建模。最大的温度下降达到 4.2°C，每年回收的热量为 0.65 kWh·人·天。在冬季，热交换器排出的废水温度最低可达 18.0°C。在考虑废水热回收时，饮用水源类型可能是一个重要因素。
