摘要： The present application relates to the field of heat pump control technologies, and provides a control method, control apparatus and control device for a heat pump system and a storage medium, so as to improve the water heating efficiency of the heat pump system. The control method for the heat pump system includes: obtaining a system requirement value of a current period and a historical level of a previous period, and performing level prediction for the current period based on the system requirement value to obtain a candidate level; comparing the candidate level with the historical level to obtain a target level; and controlling one or more heat pumps in the heat pump system to be turned on or off based on the target level.

摘要： The present invention relates to the field of heat pump water heating regulation technologies, and discloses a control method, apparatus and device for frequency regulation, and a storage medium, to improve heating efficiency of a heat pump unit. The control method for frequency regulation includes: obtaining a first heat pump outlet water temperature and a first water tank temperature, where the first heat pump outlet water temperature is used to represent a temperature of hot water produced by the heat pump unit, and the first water tank temperature is used to represent a temperature of water in the water tank after heat exchange; calculating a temperature difference between the first heat pump outlet water temperature and the first water tank temperature if the first heat pump outlet water temperature is greater than or equal to a first preset value in a first preset time period; controlling, if the temperature difference is greater than or equal to a first threshold, a compressor to perform a frequency limiting operation, and obtaining a second heat pump outlet water temperature, where the second heat pump outlet water temperature is used to represent a temperature of hot water produced by the heat pump unit after the frequency limiting operation; and controlling the compressor to stop the frequency limiting operation if the second heat pump outlet water temperature meets a first preset condition.
