Heat pump water heater control method, heat pump water heater and storage medium

The invention belongs to the technical field of household appliances, particularly relates to a heat-pump water heater control method, a heat-pump water heater and a storage medium, and aims to solve the technical problem that an existing heat-pump water heater lacks operation frequency control of a compressor in different working modes. The heat pump water heater control method comprises the steps that the initial target frequency of a compressor of the heat pump water heater is determined according to the outdoor environment temperature and the working mode of the heat pump water heater; the working frequency of the compressor is determined according to the initial target frequency of the compressor, the compressor is controlled to work at the working frequency, and the working frequency is smaller than the highest working frequency of the compressor. It can be ensured that the unit of the heat pump water heater can operate safely and efficiently in various working modes. 本申请属于家用电器技术领域，具体涉及一种热泵热水器控制方法、热泵热水器
