Performance assessment of air-source heat pumps in office buildings

Scientists have analyzed the performances of two air-source heat pumps in two small office buildings in China during the heating season. They identified the instantaneous load of the building as a critical cause of low energy efficiency. A Chinese research team has analyzed the operation and performance of two air-source heat pumps (ASHPs) during the heating season in Shenyang, a city in the cold region of China, in an effort to investigate if heat pumps may help meet increasing heat demand in the country. "To explore the key factors affecting the load characteristics of office buildings, this ...
