AI Technical Summary
In existing heat pump system control schemes, the number of units is poorly matched with the load demand, resulting in poor system stability and comfort, and is prone to water bypass and mixing phenomena.
The system adopts a dynamic grouping design, which divides the heat pump units into three grouping types. The groups are dynamically grouped according to the load rate ratio, and the target output scheme is selected by real-time load rate. The corresponding groups are turned on or off. Combined with the fixed frequency and variable frequency control of the water pump, the water pump frequency is adjusted to match the load demand.
This achieves a high degree of matching between the heat pump system and the building load, reduces water bypass and mixing phenomena, improves system stability and comfort, reduces water pump energy consumption, and enhances the overall energy efficiency of the system.
