Description

Technical Field

[0001] The present invention relates to the technical field of intelligent control of heating systems, and in particular to an air source heat pump array optimization control method, device and system. Background Art

[0002] Air-source heat pumps (ASHPs) have been widely promoted for their significant advantages, including high efficiency, cleanliness, and low carbon emissions. However, under heating conditions, ASP systems continuously absorb ambient heat, causing a significant drop in surrounding air temperature and creating a "cold island" effect. This phenomenon leads to a continuous deterioration in the thermodynamic conditions of the unit's operating environment, forcing the inlet air temperature to continue to drop. This not only reduces the system's heating performance but also increases the risk of frost on the outdoor heat exchanger surface. Given the same amount of absorbed heat, the smaller the heat pump's air heat absorption range and the higher the absorption density, the more pronounced the "cold island effect" and the more severe the unit's heating performance degradation. Due to limited building space or land, ease of operation and maintenance, and initial investment, ASPs are often deployed in clusters. Simultaneous operation of adjacent ASPs results in overlapping air heat absorption ranges, reducing the range of air heat absorption per unit and increasing its density. This significant "cold island effect" further deteriorates the unit's operating environment. Summary of the Invention

These terms of orientation or positional relationship are merely for the purpose of facilitating the description of the scheme of the present invention or simplifying the description of the specific embodiments to facilitate the rapid understanding of the scheme by technicians, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship, and therefore should not be understood as limiting the present invention.

[0154] Step 9. Reset The operation plan of the air source heat pump is obtained by re-executing steps 2 to 8 to obtain several operation plans and the corresponding air heat energy absorption density.

[0155] Step 10: Use artificial intelligence algorithms to find the minimum air heat absorption density The air source heat pump operation plan is developed and the operation of the heat pump array is controlled based on the plan.

[0156] Since the load on the user side changes in real time, it is necessary to redetermine the user side load and the air source heat pump operation plan at regular intervals and optimize them according to the above method.

[0157] Based on the above technical solution, the present invention combines the operating status of each air-source heat pump in the heat pump array with that of its neighbors to calculate the total air heat energy absorption range of the heat pump array. It further calculates the heat energy absorption density of the heat pump array, dynamically optimizing the operation plan with the goal of minimizing the heat energy absorption density. This prevents multiple heat pumps from excessively competing for air heat in a local area, which could deteriorate the heat pump's operating performance. By optimizing the operation plan of the heat pump array, the present invention effectively improves the operating environment of the heat pumps and promotes improved heat pump performance.
