Description

technical field [0001] The invention relates to the technical field of thermal energy equipment, in particular to a structure of a hot water device in which solar energy and thermal energy equipment are linked. Background technique [0002] Although the heating capacity and heating effect of solar energy are lower than that of heat pumps, solar energy is a renewable energy source, and the efficient use of solar energy is conducive to energy saving. If the solar energy and the heat pump heat the closed water tank at the same time, the heating capacity of the heat pump is high, the temperature is high, and the temperature of the solar energy heating is low, the heating effect that the solar energy can play will be weakened, so the expected energy saving effect cannot be achieved. The heating equipment is to connect the solar energy and the heat pump to the water tank at the same time to heat it. The position of the solar heating coil and the heat pump heating coil in the exist...
