when the temperature in the charging box is higher than a first preset temperature and the illumination intensity is between a second intensity value and the first intensity value, or when the temperature in the charging box is lower than or equal to a first preset temperature and the illumination intensity is higher than or equal to the second intensity value, simultaneously starting the solar heating part and the air-energy heat pump heating part; the second intensity value is less than the first intensity value;
and when the illumination intensity is smaller than the second intensity value, only the air energy heat pump heating part is started.
9. The control method according to claim 8, characterized by further comprising:
detecting the ambient temperature and the temperature of the heat carrier in the storage tank;
when the temperature in the feeding box is higher than a first preset temperature, the temperature of the heat carrier in the storage box is higher than a second preset temperature, and when the illumination intensity is higher than a first intensity value and the environmental temperature is higher than a third preset temperature, the second valve assembly is controlled to enable a heating outlet of the solar heating part to be communicated with an inlet of the heat exchange pipeline, so that the heat carrier heated by the solar heating part firstly flows through the heat storage device for heat storage and then enters the storage box;
when the temperature in the feeding box is higher than a first preset temperature, the temperature of the heat carrier in the storage box is higher than a second preset temperature, the illumination intensity is between a second intensity value and the first intensity value, and the environment temperature is higher than a fourth preset temperature, the first valve assembly is controlled to enable a heating outlet of the air-energy heat pump heating part to be communicated with an inlet of the heat exchange pipeline, so that the heat carrier heated by the air-energy heat pump heating part flows through the heat storage device for heat storage firstly and then enters the storage box; the fourth preset temperature is lower than the third preset temperature;
when the illumination intensity is lower than the second intensity value, controlling the first valve assembly to enable a heating outlet of the air-energy heat pump heating part to be communicated with the second inlet, and when the ambient temperature is lower than a fifth preset temperature, or when the temperature of a heat carrier in the storage box is lower than or equal to a second preset temperature, or when the temperature in the feeding box is lower than or equal to a first preset temperature, controlling the third valve assembly to enable an inlet of a heat exchange pipeline to be communicated with an outlet of the circulating pipe; the fifth preset temperature is less than the fourth preset temperature.
