Heat pump compressor frequency regulation and control method, device and equipment and storage medium

The embodiment of the invention discloses a heat pump compressor frequency regulation and control method and device, equipment and a storage medium. According to the technical scheme, the water inlet temperature of the heat pump unit is periodically detected, and the first temperature difference is determined according to the difference value between the water inlet temperature and the preset target temperature; determining a temperature difference change rate according to a difference value between the first temperature difference and a second temperature difference, wherein the second temperature difference is the first temperature difference determined in the previous period; determining a target frequency modulation parameter according to the first temperature difference, the temperature difference change rate and a preset contrast relationship; frequency adjustment is conducted on a compressor of the heat pump unit according to the target frequency adjustment parameter, so that the water inlet temperatur
