Ulaanbaatar - the coldest capital in the world - is home to half of Mongolia's population, much of which uses coal for household heating, contributing to high wintertime air pollution. We piloted two-stage air-to-air heat pumps in 2017, when temperatures dropped to -39 °C. These heat pumps were reliable and efficient, with an average coefficient of performance of 1.86 on the coldest days. Heat pumps' recurrent costs were similar to those of coal stoves and lower than those of resistive heaters.
乌兰巴托——世界上最冷的首都——容纳了蒙古国一半的人口，其中大部分家庭依靠煤炭取暖，导致冬季空气污染严重。2017 年，当气温降至-39°C 时，我们试点了两级空气到空气热泵。这些热泵非常可靠且高效，在最冷的日子里，平均性能系数达到 1.86。热泵的经常性成本与煤炭炉相当，低于电阻式加热器。
