AI Technical Summary

Problems solved by technology

The operation of the heat pump is affected by many factors such as the environment and the weather. Adding the heat pump to the integrated energy system will make the system operation behavior more complicated.

At present, research on the coordinated operation of heat pumps and other units in integrated energy systems is still lacking. Heat pumps are often assumed to work under nominal conditions, and existing research rarely considers the impact of meteorological conditions on the actual energy efficiency of heat pumps.
