High temperature cascade heat pump system with double medium and low temperature heat sources

open access: yesThermal Science, 2023
In response to the call for carbon neutrality and control of CO2 emission, this paper proposes a high temperature cascade heat pump system with double medium and low temperature heat sources. Compared with those with a single heat source, the new system has obvious advantages in energy saving and carbon emission.
