Problems solved by technology

[0003] Usually in the frequency conversion heat pump system, after the user sets the required target temperature, the compressor frequency of the unit is gradually adjusted through the PID algorithm based on the deviation between the actual outlet water temperature and the set temperature, and the compressor frequency is gradually adjusted to make the compressor reach the user's target temperature. It takes a long time, that is, it takes a long time to reach the target heating or cooling capacity set by the user, and in the process of gradual adjustment, the water temperature will fluctuate, and the compressor will run stably for a long time, which will affect the user experience

Description

technical field [0001] The invention relates to the technical field of heat pump control, in particular to a method, device, equipment and medium for quickly reaching the target capacity of a unit. Background technique [0002] At present, in the cooling and heating mode of the inverter heat pump air conditioner, when the outdoor ambient temperature reaches or approaches the set temperature, due to the reduction of the heat exchange load, and in order to maintain the stability of the outdoor ambient temperature, the maximum operation of the compressor is generally limited in control. The frequency makes the compressor change from high-frequency operation to low-frequency operation, so that the inverter heat pump air conditioner can also achieve energy-saving effects under the condition of meeting the set temperature. [0003] Usually, in the frequency conversion heat pump system, after the user sets the required target temperature, the compressor frequency of the unit is gra...
