Impact of variable heating loads on the performance of a return-line integrated heat pump in district heating systems
Heat pumps (HP) are a suitable solution for utilizing low-grade heat sources to meet the heating demands of modern buildings, with the return pipeline of district heating systems (DHS) representing a significant low-temperature energy source. Therefore, this study presents multivariate simulation calculations of a HP s...
